A COMPARATIVE STUDY ON HEMODYNAMIC CHANGES IN CONVENTIONAL AND UNILATERAL SPINAL ANESTHESIA

Aim: The aim of the study was to compare hemodynamic changes in unilateral and conventional spinal anesthesia. Study design: A quasi-experimental study. Location and duration of surgery: This study was performed in the Surgical Unit-I and Anesthesia Unit-II of Jinnah Hospital, Lahore for six-months duration from March 2020 to August 2020. Patients and Methods: In this study, one hundred patients who were on the list of operating rooms for an inguinal hernia were divided into two groups. Group I (n = 50) received spinal anesthesia in a sitting position, and group II (n = 50) received spinal anesthesia in the lateral position of the pressure ulcer depending on the operative side. There was no significant difference in the age and weight of the patients. Data from patients were recorded on the proforma. The comparison was made between group I and group II. Changes in heart rate, systolic and diastolic blood pressure at different time intervals were compared. Result: For 100 patients; 70 patients were ASA-I and 30 patients were ASAII. The comparison was made between group I and group II. Changes in heart rate, systolic and diastolic blood pressure at 10 minutes, 20 minutes, 30 minutes, 50 minutes, and 80 minutes after the baseline readings were compared. Baseline readings were not statistically significantly different. Mean heart rate and systolic and diastolic blood pressure were significantly reduced from baseline in both groups, but these changes in variables were insignificant in both groups. Conclusion: The hemodynamic stability is slightly better with unilateral spinal anesthesia, but the results are statistically insignificant.
