Abstract
L
aparoscopic cholecystectomy is the procedure of choice in treatment of the symptomatic cholelithiasis, an expanding trend to render this procedure an ambulatory procedure.
Segmental thoracic spinal provides tense relaxation with relatively better postoperative analgesia in comparison to general anesthesia.
In this study, 40 patients were divided in to 2 groups:
Group (I): 20 patients undergone laparoscopic cholecystectomy using segmental thoracic spinal anesthesia.
Group (II): 20 patients undergone laparoscopic cholecystectomy using general anesthesia.
The following measurements were taken intra operatively and postoperatively:
• Hemodynamics (heart rate, mean arterial blood pressure).
• The pain score and the sedation score in the first 24 hours postoperatively.
• The total amount of supplemental analgesics given postoperatively and the time to the first analgesic dose.
The results of the statistically analyzed data obtained can be summarized as the following:
There were statically significant differences between the 2 groups as regard pain score and the time of the first analgesic dose.
There was no statically significant between the 2 groups as regard the sedation score except at the 2 hours postoperatively
There was a significant reduction in the total analgesic supplementation in the first 24 hours postoperatively.
It was concluded from the results that segmental thoracic anesthesia is a safe technique and provides a better analgesia and a lower incidence of postoperative nausea and vomiting and no significant difference in the sedation score and there was less analgesic consumption in the first 24 hours and free of complication.
