Randomized Controlled Trial Clinical TrialThe interaction effect of perioperative cotreatment with dextromethorphan and intravenous lidocaine on pain relief and recovery of bowel function after laparoscopic cholecystectomy.
Both dextromethorphan (DM) and IV lidocaine improve postoperative pain relief. In the present study, we evaluated the interaction of DM and IV lidocaine on pain management after laparoscopic cholecystectomy (LC). One-hundred ASA physical status I or II patients scheduled for LC were randomized into four equal groups to receive either: (a) chlorpheniramine maleate (CPM) intramuscular injection (IM) 20 mg and IV normal saline (N/S) (group C); (b) DM 40 mg IM and IV N/S (group DM); (c) CPM 20 mg IM and IV lidocaine 3 mg . kg(-1) . h(-1) (group L); or (d) DM 40 mg IM and IV lidocaine (group DM+L). ⋯ Patients of the DM+L group exhibited the best pain relief and fastest recovery of bowel function among groups. Patients in the DM and L groups had significantly better pain relief than those in the C group. The results showed an additional effect on pain relief and a synergistic effect on recovery of bowel function when DM was combined with IV lidocaine after LC.

Randomized Controlled Trial Comparative Study Clinical TrialSpinal 2-chloroprocaine: a comparison with small-dose bupivacaine in volunteers.
Ambulatory surgery continues to increase nationwide. Because spinal lidocaine is associated with transient neurologic symptoms, many clinicians have switched to small-dose bupivacaine for outpatient spinal anesthesia. However, bupivacaine often produces inadequate surgical anesthesia and has an unpredictable duration. ⋯ However, time to simulated discharge (including time to complete block regression, ambulation, and spontaneous voiding) was significantly longer with bupivacaine (2-CP 113 +/- 14, bupivacaine 191 +/- 30 min, P = 0.0009). No subjects reported transient neurologic symptoms or other side effects. We conclude that spinal 2-CP provides adequate duration and density of block for ambulatory surgical procedures, and has significantly faster resolution of block and return to ambulation compared with 7.5 mg of bupivacaine.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialThe cyclooxygenase-2-specific inhibitor parecoxib sodium is as effective as 12 mg of morphine administered intramuscularly for treating pain after gynecologic laparotomy surgery.
Parecoxib sodium, the injectable prodrug of valdecoxib, is a cyclooxygenase-2-specific inhibitor that is effective in the treatment of postoperative pain. In this randomized, double-blind, placebo-controlled study, we compared the efficacy of a single dose of parecoxib sodium 40 mg IM with single doses of morphine 6 and 12 mg IM in treating postoperative pain after gynecologic surgery requiring a laparotomy incision. ⋯ The incidence of adverse events in the active treatment groups was similar to that observed with placebo. Parecoxib sodium, 40 mg IM, has been shown to be as effective as clinically relevant doses of morphine in patients after gynecologic laparotomy surgery.
