Paravertebral somatic nerve block compared with peripheral nerve blocks for outpatient inguinal herniorrhaphy

摘要: Background Inguinal herniorrhaphy (IH) is a common outpatient procedure, yet postoperative pain and anesthetic side effects remain problem. Paravertebral somatic nerve blocks (PVB) have the potential to offer unilateral abdominal wall anesthesia long-lasting relief with minimal effects. We compared PVB peripheral neural for IH. Methods Forty-six patients scheduled IH were entered into this prospective, single-blind study. All underwent standardized general anesthetic. Patients randomly assigned receive (levels T10-L2) preoperatively (n = 24) or an intraoperative block (PB) by surgeon 22), using 0.5% ropivacaine (40 mL). Opioid use, verbal analog scores, documented 72 hours. Results The use of opioids during surgery was less group 162 ± 70 mg than PB group, 210 60 (P .02). Need in PACU (39%) (61%) .002). Time until first after discharge not different between groups, 312 446 minutes 425 384 .12). Of patients, 29% used no at all 18% Mean time oxycodone similar 303 469 295 225 .18). Oxycodone also similar; 35 34 versus 49 42 .30). More (50%) required antiemetic treatment postanesthesia care unit (21%) Conclusions This study shows that provides analgesia equivalent extensive inguinal herniorrhaphy, offering alternative method management perhaps fewer
