Spinal/epidural block as an alternative to general anesthesia for laparoscopic appendectomy: a prospective randomized clinical study.

UNASSIGNED

Laparoscopic appendectomy (LA) has been generally performed under general anesthesia. Laparoscopic appendectomy is rarely performed under regional anesthesia because of pneumoperitoneum-related problems.

UNASSIGNED

To compare spinal/epidural anesthesia (SEA) and general anesthesia (GA) during LA with respect to perioperative and postoperative adverse events and postoperative pain.

UNASSIGNED

Fifty patients, aged 18-65, who underwent LA, were randomly allocated to two groups: the GA (n = 25) and SEA (n = 25) groups. Perioperative and postoperative adverse events, postoperative pain level, and patient satisfaction were compared between the groups.

UNASSIGNED

None of the patients needed conversion to an open procedure or conversion from SEA to GA. In the SEA group we encountered shoulder pain in 6 (24%) patients, abdominal discomfort/pain in 4 (16%) patients, anxiety in 4 (16%) patients, and hypotension in 2 (8%) patients intraoperatively. Also, post-spinal headache was observed in 5 (20%) patients in the SEA group. Postoperative right shoulder pain was significantly higher in the GA group compared to the SEA group (32% vs. 8%; p = 0.037). In the SEA group the incidence of urinary retention and in the GA group the incidence of postoperative nausea and vomiting (PONV) were higher, but these differences were not statistically significant. The postoperative surgical pain level was significantly lower in the SEA group (p < 0.001).

UNASSIGNED

Spinal/epidural anesthesia is effective and safe in ASA I healthy patients undergoing LA. Less postoperative pain, PONV and shoulder pain are the advantages of SEA compared to GA.
