Article Analysis of the Effect of Perioperative Magnesium Sulphate on Minimal Alveolar Concentration of Desflurane Using Bispectral Index Monitoring(John Libbey Eurotext Ltd, 2011) Tomak, Yakup; Tekin, Murat; Kati, Ismail; Belenli, Ceyda; Aydogmus, MeltemBackground. In this study we aimed to analyze the effect of perioperative magnesium sulphate (MgSO4) on minimal alveolar concentration (MAC) of desflurane using bispectral index (BIS) monitoring. Patients and methods. Sixty patients undergoing abdominal surgery under general anesthesia were randomized into two groups: Mg - receiving perioperative MgSO4 supplementation and C - control. Anesthesia was titrated to maintain the BIS value between 45-55. Results. MAC values, tachycardia and hypertension during intubation was found to be lower in group Mg compared to group C (p<0.001). Time to extubation, verbal cooperation and eye opening was longer in patients receiving infusion of MgSO4 (p<0.001). Conclusion. We concluded that perioperative MgSO4 infusion may be used as an adjunct as it decreases MAC of desflurane and suppresses the hemodynamic response to intubation.Article Anesthetic Management of Patients With Melkersson Rosenthal Syndrome(Springer Tokyo, 2008) Tekin, Murat; Kati, IsmailMelkersson Rosenthal Syndrome (MRS) is a rare disorder characterized by relapsing facial paralysis, persistent or recurrent orofacial edema, and lingua plicata. It may cause difficult airway, drug allergy, and angioedema. In our anesthetic management of two patients with MRS, preanesthetic immunological blood examination and skin tests for hypersensitivity to anesthetic drugs were applied. Because the principal goal is to avoid all factors that may stimulate, an allergic reaction, anesthetic drugs known to trigger urticaria were avoided. Body and operating room temperatures, changes of which may trigger allergic reactions, were kept constant during the perioperative period. Emergency precautions were taken for probable angioedema. MRS is a rare syndrome, and if its manifestations are misunderstood as simple facial paralysis, it may be overlooked by anesthesiologists. Anesthesiologists must be careful of several problems in patients with MRS.Article The Axon Number of the Rat Sciatic Nerve: a Stereological Study(Kafkas Univ, veteriner Fakultesi dergisi, 2013) Ragbetli, Cennet; Yalama, Mustafa; Kati, Ismail; Ulkay, Muzaffer Basak; Esener, Osman Burak; Bozkurt, Hasan Hakan; Ragbetli, Murat CetinThis study was designed to determine with stereological methods the number of axons in the sciatic nerve as a result of peripheral nerve blockage following injection of lidocaine and prilocaine into hind limb muscle. Nine adult female Sprague-Dawley rats weighted 150-200 g were used in the study. Ketamine was employed intraperitoneal to the rats as 50 mg/kg. The prilocaine and lidocaine were equally (5 mg/ml) injected to the left and right limbs of the 4 rats. As a control group, isotonic sodium chloride (0.9%) was performed as 0.2 ml into the extremities of the remaining 5 rats. When the application completed, surrounding muscles and soft tissues as well as sciatic nerve were dissected as 0.5x1.0 cm length. In order to determine neurotoxic effects of lidocaine and prilocaine on sciatic nerve, the number of axons was computed by unbiased stereological method. Following of the square root transformation, Mann-Whitney U test was performed to compare groups. When the unbiased comparisons were executed to both groups, the effects of lidocaine and prilocaine on sciatic nerve were found statistically non-significant.Article Comparing Effects of Low and High-Flow Anesthesia on Hemorheology and Coagulation Factors(Professional Medical Publications, 2015) Binici, Orhan; Kati, Ismail; Goktas, Ugur; Soyaral, Lokman; Aytekin, Osman CagatayObjectives: In the current study, we compared the effects of low- and high-flow anesthesia techniques on hemorheology and coagulation parameters in patients who received sevofluran. Methods: Forty patients classified as Risk Group I-II according to American Society of Anesthesiologists' (ASA) guidelines who were scheduled to undergo general anesthesia were randomly assigned to one of two groups. Low-flow anesthesia was administered to the first group, and high-flow anesthesia was used in the second group. Blood samples were obtained in the preoperative and peroperative periods (at 60 and 120 min) for determination of blood and plasma viscosity, plasma oncotic pressure, international normalized ratio (INR), phorotrombin time (PT), activated partial phorotrombin time (aPTT) and fibrinogen. Blood was also drawn for analysis of factor VIII (FVIII) activity, which was measured in the preoperative period and at postoperative six hour. Results: The peroperative plasma viscosity was significantly low in Group 1 relative to Group 2. aPTT was significantly elevated at 60 minutes in Group 1 relative to Group 2, but the increase at 120 minutes was not significant. Conclusion: The effects of low-flow anesthesia on hemorheology were greater than those of high-flow anesthesia.Article Comparison of the Effects of Room Air and N2o + O2 Used for Proseal Lma Cuff Inflation on Cuff Pressure and Oropharyngeal Structure(Springer Tokyo, 2008) Tekin, Murat; Kati, Ismail; Tomak, Yakup; Yuca, KoksalThis study aimed to evaluate the effects of different inflating gases used for ProSeal LMA (PLMA) cuff inflation on cuff pressure, oropharyngeal structure, and the incidence of sore throat. Eighty patients (American Society of Anesthesiologists; ASA I-II) were randomly divided into two groups. PLMA cuff inflation was achieved with appropriate volumes of 50% N(2)O + 50% O(2) in group I and room air in group II, respectively. When the PLMA was removed, oropharyngeal examination was carried out immediately, using a rigid optical telescope. Patients were asked about sore throat symptoms postoperatively. Cuff pressures were significantly lower in group I, except at the initial pressure measurement. Cuff pressure was positively correlated with the length of the operation in group II, and negatively correlated in group I. PLMA cuff inflation with room air led to increased cuff pressure during the operation, possibly due to the diffusion of N(2)O into the cuff. We consider that a PLMA cuff inflated with an N(2)O-O(2) mixture is convenient, especially in operations in which N(2)O has been used.Article Cylothorax Developing Due To Thrombosis in the Subclavian Vein(Modestum Ltd, 2013) Isik, Yasemin; Goktas, Ugur; Binici, Orhan; Kati, IsmailChylothorax, which is a rare complication of central venous catheterization, is an accumulation of lymphatic fluid in the pleural space as a result of impairment of the integrity of ductus thoracicus. In this case report, we will look over chylothorax related to thrombus developing following subclavian vein catheterization.Article The Differences in Cerebral Oxygenation Among Patients Undergoing Thyroidectomy in Different Positions and Comparison of Their Effects on Nausea-Vomiting(Drunpp-sarajevo, 2012) Gunes, Haci Yusuf; Goktas, Ugur; Kati, Ismail; Yuce, Hasan Husnu; Bartin, SerapBackground: Hyperextension of the patient's neck associated with distortion and vasospasm of the vertebral and internal carotid arteries intra-operatively. In this study we aimed to investigation of whether there is effects of supine, slight neck hyperextension and semi-seated and neck hyperextension positions of patients on postoperative nausea and vomiting (PONV) via regional cerebral oxygen saturation (rSO(2)). Methods: ASA I-II group of 40 adult patients for whom elective thyroid operations under general anesthesia (GA) were planned, were divided into 2 randomized groups. The patients in the Group 1 were positioned in the hyperextension of the neck at 45 degrees semi-seated position and in the Group 2 patients were positioned in the supine position. Results: The heart rate (HR), and mean arterial pressure (MAP) values were found to be statistically significantly higher in the first group than the second group in a few values (p<0.05). There were no significant differences between the groups when they were compared for left and right cerebral oxygen saturation (p>0.05). No correlation was determined between the cerebral arterial desaturation and rates of PONV. Conclusions: It was concluded that cardiovascular changes due to hyperextension of the neck in a semi-seated position during surgery under general anesthesia, despite a cerebral desaturation in rSO(2) that remained within the cerebral auto-regulation range and there is no correlation of PONV with either neck hyperextension in the semi-seated position or desaturation conditions with less than a 20% decrease in rSO(2).Letter Difficult Airway Management in Lymphangiomatos Macroglossia(Blackwell Publishing, 2008) Goktas, Ugur; Tekin, Murat; Kati, Ismail; Toprak, Kemal; Yuece, Hasan HuesnueArticle Effect of Dexmedetomidine Iv on the Duration of Spinal Anesthesia With Prilocaine: a Double-Blind, Prospective Study in Adult Surgical Patients(Elsevier Science inc, 2007) Tekin, Murat; Kati, Ismail; Tomak, Yakup; Kisli, ErolBackground: The duration of spinal anesthesia with prilocaine has been poorly documented and no English-language study has been published regarding the effects of dexmedetomidine on the duration of anesthesia with spinal prilocaine. Objective: The aim of this study was to assess the effects of dexmedetomidine IV on the duration of action of prilocaine and its associated adverse events (AEs) in spinal anesthesia. Methods: In this double-blind, prospective study, patients classified as American Society of Anesthesiologists grade I to 11 who were to undergo lower abdominal, anorectal, or extremity surgery with a spinal anesthetic were assigned to I of 2 groups. All patients were administered prilocaine 2% for spinal anesthesia. Within 10 minutes after spinal anesthesia was initiated, group I received a loading dose of dexmedetomidine 1 mu g/kg IV, followed by a maintenance dose of 0.4 mu g/kg - h for 50 minutes; group 2 (control) received the same amount of physiologic saline in the same time frame. Mean arterial pressure (MAP), heart rate (HR), duration of sensory and motor blockade, and sedation scores were tracked. Patients were observed for 4.5 hours after surgery, with follow-ups occurring up to 96 hours after surgery. Results: Eighty-three patients were assessed for study inclusion, 23 of whom were excluded. Sixty patients (42 men, 18 women; mean [SD] age, 40.56 [16.861 years) were included in the study. MAP was similar in the 2 groups throughout the study. Mean (SD) HR was significantly lower in group I compared with group 2 at 20 minutes (70.43 [19.28] vs 77.63 [18.14] beats per minute, respectively; P = 0.02). The mean (SD) duration of the persistence of sensory anesthesia (ie, the time required for the maximal level of anesthesia to regress 2 dermatomes) was significantly longer in group I compared with group 2 (148.33 [21.18] vs 122.83 [18.73] minutes; P < 0.001). The mean (SD) time to complete abolishment of motor blockade was also significantly longer in group I than in group 2 (215.16 [25.10] vs; 190.83 [18.57] minutes; P < 0.001). The average sedation score in group I was significantly higher than in group 2 (P < 0.001) during anesthesia. Significantly more patients in group I required atropine than those in group 2 (9 vs 2 patients; P < 0.001) to treat bradycardia. There was no significant between-group difference in the number of patients who received ephedrine to treat hypotension. One patient in each group reported waist and back pain; 2 patients in each group reported nausea. Shivering occurred in 0 and 5 patients in groups I and 2, respectively; the between-group difference in AEs was not statistically significant. Paresthesia, postdural puncture headache, allergic reactions, total spinal anesthesia, urinary retention, or vomiting-AEs commonly associated with spinal anesthesia-were not observed or reported by either group. Conclusions: The results of this study suggest that dexmedetomidine IV significantly prolonged the duration of spinal anesthesia and provided a significantly higher level of sedation compared to placebo in this group of adult surgical patients. The treatment was generally well tolerated in all patients.Conference Object The Effect of Magnesium Sulfate on Uncontrollable Contractions in a Tetanus Case(Lippincott Williams & Wilkins, 2012) Kati, Ismail; Goktas, Ugur; Cagan, Eren; Guzel, Abdulmenap; Bartin, SerapTetanus is a rare disease caused by the exotoxins of Clostridium tetani. Higher mortality rates have been reported among the elderly and in the newborn. In this report of a tetanus case, the treatment and prognosis of contractions resistant to diazepam, midazolam, and atracurium infusion has been evaluated.Article Effects of Fentanyl With Levobupivacaine on Cognitive Functions and Cerebral Oxygenation(Modestum Ltd, 2013) Cegin, Muhammet B.; Goktas, Ugur; Kati, Ismail; Guzel, Abdulmenap; Binici, OrhanPreoperative risk assessment may fail in most patients who may be exposed to postoperative neurological sequelae. The aim of this study was to assess the effects of Fentanyl added to epidural levobupivacaine on cerebral oxygenation and cognitive functions. There was a negative correlation between age and MMT, and a positive correlation between SpO(2) and MMT. MMT scores of Group 2 at postoperative first hour and fifth hours were lower than those of Group 1. It was concluded that while fentanyl added to epidural local anesthetic had no effect on hemodynamic parameters, SpO(2), and right-left cerebral oxygen saturation, and although it may have caused a decrease in MMT scores in the early postoperative period, it did not cause impairment in cognitive functions.Article The Effects of Intravenous Dexmedetomidine on Spinal Hyperbaric Ropivacaine Anesthesia(Springer Japan Kk, 2010) Elcicek, Kamuran; Tekin, Murat; Kati, IsmailIn this study we investigated the effects of intravenously administered dexmedetomidine on the duration of hyperbaric ropivacaine in spinal anesthesia, and the side effects. In a prospective, double-blind study, sixty ASA I-II patients were randomized to two groups of 30 individuals. All patients were administered hyperbaric ropivacaine (22.5 mg) for spinal anesthesia. Intravenous dexmedetomidine was administered in group I for 60 min, physiological saline at the same amount and duration was infused in group II. Measurements of mean blood pressure before and after the procedure revealed significant decreases in group I compared with group II after 20, 25, and 30 min. The times for two dermatomes regression of the blockade and complete resolution of motor blockade were significantly prolonged in group I. The sedation score in the dexmedetomidine group was significantly increased compared with controls. Atropine requirement was found to be significantly higher in group I than in group II. Our results show that intravenously administered dexmedetomidine prolonged the duration of spinal anesthesia, provided sufficient sedation, and had few side effects. Therefore, dexmedetomidine is appropriate during spinal anesthesia, if the anesthesiologist is alert for development of bradycardia.Article Effects of Lidocaine Infiltration on Cost of Rhinoplasty Made Under General Anesthesia(Lippincott Williams & Wilkins, 2011) Goktas, Ugur; Isik, Daghan; Kati, Ismail; Atik, Bekir; Soyoral, LokmanThis study aimed to compare the effects of combined and noncombined lidocaine with adrenaline infiltration in general anesthesia (GA) procedures, in which the standard anesthesia depth is monitored by Bispectral Index monitoring, on minimum alveolar concentration (MAC) levels and the costs. Following approval by the local ethics committee, an American Society of Anesthesiologists physical status I-II group of 40 adult patients for whom elective rhinoplasties under GA were planned was divided into 2 double-blind randomized groups. In group 1, GA and lidocaine + adrenaline were administered, whereas in group 2, only GA and adrenaline were administered. All the patients who had been taken to the operation room underwent electrocardiography and measurements of the peripheral oxygen saturation, end-tidal carbon dioxide, heart rate, mean blood pressure, and Bispectral Index monitoring. Using the operation time and the MAC% values, the total consumed inhalation agent amounts were calculated, and the cost difference was determined. The mean blood pressure values were lower in group 1 (P < 0.05). In group 1, the MAC% was 20.83% lower than that of group 2; the consumed desflurane amount was 20.29%, and the cost was 20.29% lower than that of group 2 (P G 0.05). In rhinoplasties under GA, the lidocaine + adrenaline combination infiltration not only decreased inhaled anesthetic requirement and cost but also supported the hemodynamic stability. In addition, surgical satisfaction increased in the lidocaine + adrenaline group because of small number of agitated patients during the recovery period.Article Effects of Sugammadex and Neostigmine on Renal Biomarkers(int Scientific information, inc, 2016) Isik, Yasemin; Palabiyik, Onur; Cegin, Bilal Muhammed; Goktas, Ugur; Kati, IsmailBackground: Neostigmine, the currently commonly used agent for reversal of neuromuscular blockade. Sugammadex is a novel and unique compound designed as an antagonist of steroidal neuromuscular blockers. In this study, we evaluated the effects of sugammadex or neostigmine on kidney functions in patients scheduled for elective surgery. Material/Methods: Patients scheduled for a surgical procedure under desflurane/opioid anesthesia received an intubating dose rocuronium. Patients were divided into 2 groups receiving either sugammadex or neostigmine atropine to reverse neuromuscular blockade. Cystatin C, creatinine, urea, blood urea nitrogen, sodium, potassium, and calcium levels in the blood and alpha(1)microglobulin, beta(2)microglobulin, and microalbumin levels in the urine were measured. Results: There was no significant difference between the groups with regard to the demographic data. In the Neostigmine Group, although beta(2)microglobulin and microalbumin were similar, a significant increase was found in the postoperative alpha(1)microglobulin and cystatin C values. In the Sugammadex Group, although beta(2)-microglobulin and cystatin C were similar, a significant increase was found in the postoperative alpha(1)-microglobulin and microalbumin values. The only significant difference was cystatin C value variation in the Neostigmine Group compared to the Sugammadex Group. Conclusions: We believe that the use of more specific and sensitive new-generation markers like cystatin C to evaluate kidney function will provide a better understanding and interpretation of our results. Sugammadex has more tolerable effects on kidney function in patients than does neostigmine. However, when compared to preoperative values, there is a negative alteration of postoperative values. Neostigmine and sugammadex do not cause renal failure but they may affect kidney function.Article Effects of Theophylline With Methylprednisolone Combination Therapy on Biomechanics and Histopathology in Diaphragm Muscles of Rats(Springer/plenum Publishers, 2016) Yuzkat, Nureddin; Kati, Ismail; Isik, Yasemin; Kavak, Servet; Goktas, Ugur; Cengiz, NurettinThe purpose of this study was to investigate the effects of theophylline and methylprednisolone on the mechanical response and histopathology of hemidiaphragm muscle in rats. In the current study, we aimed to investigate the effects of theophylline and methylprednisolone, which are frequently used in clinics and which have different effects on the respiratory system and on the biomechanics and histopathology of the diaphragm muscle. The study included four groups of rats. Group T received 1 mg/kg of intraperitoneal theophylline, group M received 2 mg/kg of intraperitoneal methylprednisolone, group TM received 1 mg/kg of intraperitoneal theophylline plus 2 mg/kg of intraperitoneal methylprednisolone, and group K received of 1 mL intraperitoneal isotonic solution (of 0.9 % NaCl). The medications were continued for 7 days in each group. The rats underwent cervical dislocation under anesthesia on the eighth day, and their diaphragm samples were extracted. The left hemidiaphragm was used for the investigation of biomechanical parameters, and the right hemidiaphragm was used for the histopathological evaluation. It was observed that the medication administered in group T increased the contraction strength and duration compared with that in group M. Additionally, the duration of semi-relaxation was prolonged in group T compared with group M. The highest contraction strength and the longest contraction period among all of the groups were observed in group TM. It was concluded that the combined use of theophylline and methylprednisolone had positive effects on the contraction strength and the durations of contraction and semi-relaxation of the diaphragm muscle. In addition, both drugs had synergistic effects on each other.Article Efficiency of Hematocrit, Lymphocyte, C-Reactive Protein and Transferrin Levels in Predicting Mortality in Intensive Care Unit Patients(Modestum Ltd, 2015) Palabiyik, Onur; Isik, Yasemin; Cegin, Muhammed Bilal; Goktas, Ugur; Kati, IsmailThe effectiveness of many physiological parameters and laboratory tests was investigated in predicting mortality. In this study, we investigated hematocrit, C-reactive protein, transferrin and total lymphocyte count along with Acute Physiology and Chronic Health Evaluation II and Glasgow Coma Scores of patients who were hospitalized in the intensive care unit. The data were retrospectively analyzed from hospital information management system, doctors' records and nurse observing forms. The mortality rate was 42.6%. The Acute Physiology and Chronic Health Evaluation II scores were significantly higher in cases with mortality compared to those without mortality. The admission and discharge Glasgow Coma Scores were significantly lower in patients who showed mortality compared with patients without mortality. Admission and discharge hematocrit and transferrin values were significantly lower in cases with mortality compared to those without mortality. Discharge C-reactive protein values were significantly higher in cases with mortality compared to those without mortality. Discharge total lymphocyte count values were significantly lower in cases with mortality compared to those without mortality. Consequently, we believe that hematocrit and transferrin values at the time of admission to the intensive care unit and total lymphocyte count and C-reactive protein at the time of discharge from the intensive care unit can be effective in predicting mortality.Article Evaluation of Nosocomial Infections.and Antibiotic Resistance Profiles in the Anesthesiology Intensive Care Unit(Galenos Yayincilik, 2010) Goktas, Ugur; Yaman, Gorkem; Karahocagil, Mustafa Kasim; Bilici, Adnan; Kati, Ismail; Berktas, Mustafa; Akdeniz, HayrettinObjective: We aimed to determine the etiological agents of nosocomial infections and susceptibility patterns in our intensive care unit (ICU). Materials and methods: The study included 341 patients (mean age 47.8-122.7 years) who were admitted to our ICU longer than 72 hours between May 2007 and July 2008. All the patients were followed-up daily together with infectious disease specialists. Nosocomial infections were defined according to the CDC criteria (Centers for Disease Control and Prevention). Blood cultures and cultures from infectious foci were taken from patients who were thought to have a nosocomial infection. Results: A total of 141 episodes of nosocomial infection developed in 57 patients (16.7%), including ventilator-associated pneumonia (74 episodes, 52.5%), primary bacteremia (n=49, 34.8%), urinary system infections (n=15, 10.6%), and surgical site infections (n=3, 2.1%). Isolated bacteria were as follows: S. aureus (22%), P. aeruginosa (15.6%), Acinetobacter spp. (14.2%), E. coli (14.2%), Klebsiella spp (11.4%), coagulase-negative staphylococcus (CNS) (7.8%), Enterococcus spp. (5%), Enterobacter spp. (4.3%), S. pneumoniae (2.8%), and S. maltophilia (2.1%). Resistance rates to oxacillin were 90.3% in S. aureus and 81.8% in CNS isolates. In Enterococcus spp., resistance to ampicillin was 71.4%, high-level aminoglycoside resistance was 85.7%, with no resistance to vancomycin. Extended-spectrum beta-lactamase-positive strains accounted for 70% for E. coil and 93.7% for Klebsiella species. Conclusion: Monitoring of nosocomial infections and infectious agents together with resistance rates in the ICU has great importance in both the prevention of infections and rational antibiotic use.Article Fibre-Optic Bronchoscopy-Assisted Percutaneous Dilatational Tracheostomy by Guidewire Dilating Forceps in Intensive Care Unit Patients(B C decker inc, 2008) Yuca, Koeksal; Kati, Ismail; Tekin, Murat; Yilmaz, Nebi; Tomak, Yakup; Cankaya, HakanObjective: The purpose of this study was to prospectively analyze intensive care unit patients with fibre-optic bronchoscopy assisted percutaneous dilatational tracheostomy by guidewire dilating forceps (GWDF; Griggs percutaneous tracheostomy). Design: Prospective study. Setting: A tertiary care centre. Materials and Methods: Fifty-two critically ill patients (32 men and 20 women), aged 16 to 84 years (mean +/- 6 SD 42 +/- 1.6 years) who required endotracheal intubation for longer than 15 days were consecutively selected to undergo tracheostomy by the GWDF technique. The diagnoses of the patients and intraoperative and postoperative complications were recorded. Results: The patients were mechanically ventilated for an average of 14.8 +/- 1.2 days. The duration of the GWDF technique was 4.9 +/- 1.7/min. Intraoperative complications occurred in 10 (19.2%) patients: hemorrhage in 3 cases, puncture of the tracheal tube in 2 cases, difficult cannulation in 2 cases, difficult dilatation in 1 case, false passage in 1 case, and inadvertent extubation in 1 case. Postoperative complications occurred in three (5.7%) patients, stomal cellulitis in one case, subcutaneous emphysema in one case, and difficult recannulation in the remaining case. Conclusions: Fibre-optic bronchoscopy-assisted percutaneous dilatational tracheostomy by GWDF is a simple and fast technique for inserting a tracheal cannula.Article Glutamine Supplemented Parenteral Nutrition To Preventventilator-Associated Pneumonia in the Intensive Care Unit(Galenos Publ House, 2012) Aydogmus, Meltem Turkay; Tomak, Yakup; Tekin, Murat; Kati, Ismail; Huseyinoglu, UrfettinObjective: Ventilator-associated pneumonia (VAP) is a form of nosocomial pneumonia that increases patient morbidity and mortality, length of-hospital stay, and healthcare costs. Glutamine preserves the intestinal mucosal structure, increases immune function, and reduces harmful changes in gut permeability in patients receiving total parenteral nutrition (TPN). We hypothesized that TPN supplemented by glutamine might prevent the development of VAP in patients on mechanical ventilator support in the intensive care unit (ICU). Material and Methods: With the approval of the ethics committee and informed consent from relatives, 60 patients who were followed in the ICU with mechanical ventilator support were included in our study. Patients were divided into three groups. The first group received enteral nutrition (n=20), and the second was prescribed TPN (n=20) while the third group was given glutamine-supplemented TPN (n=20). C-reactive protein (CRP), sedimentation rate, body temperature, development of purulent secretions, increase in the amount of secretions, changes in the characteristics of secretions and an increase in requirement of deep tracheal aspiration were monitored for seven days by daily examination and radiographs. Results: No statistically significant difference was found among groups in terms of development of VAP (p=0.622). Conclusion: Although VAP developed at a lower rate in the glutamine-supplemented TPN group, no statistically significant difference was found among any of the groups. Glutamine-supplemented TPN may have no superiority over unsupplemented enteral and TPN in preventing VAP.Article Guillain-Barre Syndrome Following Spinal Anaesthesia(Coll Physicians & Surgeons Pakistan, 2013) Sayin, Refah; Kati, Ismail; Isik, Yasemin; Gunes, MustafaGuillain-Barre Syndrome (GBS) is the most common disease resulting in acute diffuse flaccid paralysis. It is an autoimmune disease that can occur at any age. The clinical course is characterized by weakness in the arms and legs, areflexia and the progression of muscle weakness from the lower limbs to the upper limbs. The most common causes of GBS include infections, vaccinations, surgery and some medicines. We present the case of a 48 years old male patient, who developed GBS after undergoing surgery for renal calculus, under spinal anaesthesia. In this case report, we presented a rather rare case of GBS occurring following spinal anaesthesia.
