Background/Objectives: According to Watson's Human Care Theory, an improved environment influences patients' care processes. The purpose of this study was to examine the effect of an improved environment, according to Watson's Human Care Theory, on sleep quality, anxiety, and depression in patients undergoing open heart surgery. Methods: Upon admission to the ward from the postoperative intensive care unit, the experimental group underwent environmental remediation for three days. The environmental arrangements ensured that the patient's room maintained an appropriate temperature range of 18-26 degrees C and humidity values of 30-50%. Monitoring took place at 21:00, 22:00, and 23:00 on Days 1, 2, and 3, at which times, the brightness of the patient rooms gradually decreased. On the morning of the fourth day, the patients were interviewed face to face, and research questionnaires were filled out (ClinicalTrials.gov identifier of the manuscript: NCT06744023). Results: After the implementation of an improved environment in accordance with Watson's Human Care Theory, the sleep duration of the patients in the experimental group (5.91 h) was higher than that of the control group (4.1 h). At the same time, the mean sleep quality score was measured as 300 +/- 15.33 in the experimental group and 116.33 +/- 14.94 in the control group. In addition, anxiety and depression levels were lower in the experimental group (5.63 +/- 0.59; 4.53 +/- 0.42) compared with the control group (12.03 +/- 0.85; 10.03 +/- 0.82). Conclusions: We recommend implementing improved environmental arrangements in accordance with Watson's Human Care Theory to improve sleep quality and reduce anxiety and depression levels in patients undergoing open heart surgery.
The Effect of Local Anaesthetic Agents on Opioid Use and Recovery in Patients Undergoing Open Heart Surgery: a Randomized Controlled Study
(Bmc, 2025) Azizoglu, Hatice; Asam, Mehmet; Gurkan, Zeynep; Bozkurt, Yasemin; Demir, Canan
BackgroundAfter open heart surgery, patients experience high levels of pain at the sternotomy incision site and around the chest tube(s), affecting their recovery. This study was conducted to determine the effects of local anesthetic application around the sternotomy incision site and chest tube(s) on the amount of opioids used and recovery after surgery in patients undergoing open heart surgery.MethodsThis randomized controlled experimental study was conducted with a total of 60 patients, with 30 patients in the experimental group and 30 patients in the control group. In the experimental group, LIDOFAST 40 mg/2 ml + 0.025 mg/2 ml, a local anesthetic agent, was applied to the postoperative sternotomy incision site and around the chest tube(s) in addition to routine treatment. Patients in the control group received only routine treatment. Data were collected using the "Descriptive Characteristics Form" and the "Postoperative Recovery Index".ResultsIt was observed that postoperative pain started later, opioid consumption decreased, and postoperative recovery was faster in the experimental group. As the number of chest tubes increased, recovery was delayed in all groups, and as the number of opioids used increased, postoperative recovery was negatively affected in the control group.ConclusionsIn this study, local anesthetic application to the sternotomy incision site and around the chest tubes after open heart surgery was found to reduce postoperative opioid consumption and positively affect recovery.Trial registrationCurrent Controlled Trials NCT06642077 (Retrospectively registered).
