Abstract

The study aimed to investigate the effects of spinal anaesthesia on patients with hypotension and bradycardia. The procedure was uneventful, with no conversions from spinal to general anaesthesia. The study found significant variations in pulse rate after spinal and during GB handling in group S, which may be due to vagal stimulation or hemodynamic response to laryngoscopy and intubation. Bradycardia was an expected side effect due to rapid peritoneal stretch and vagal stimulation in laparoscopic cholecystectomy operations. The incidence of bradycardia was 11.43% and 2.86% in group S and group G, respectively. Aim and objectives: Hypotension and bradycardia were easily managed with inj. Mephentermine and inj. Atropine, respectively. Pre-anaesthetic hydration with 10ml/kg of ringer lactate prevented repeated hypotension occurrences. The decrease in pulse rate and BP in group S was due to the residual analgesic effect of local anaesthetic in subarachnoid space. Methods: Shore tip pain was a significant intraoperative problem caused by the irritation of the subdiaphragmatic area with CO2. Previous studies have shown that maintaining intra-abdominal pressure below 10 mmHg reduces right shoulder pain and respiratory distress due to diaphragm irritation. However, the study's high intraabdominal pressure created during pneumoperitoneum affected hemodynamic values negatively and contributed to shoulder pain. Results: The surgical team was satisfied with sufficient abdominal relaxation during the operation in spinal anaesthesia. However, further studies with a larger sample size may be conducted to support observations. All patients in the spinal anaesthesia group remained awake and oriented at the end of surgery, with a smooth transition of pain in the postoperative period. Avoidance of GA and opioids contributed to the lack of deterioration in cognitive function.
