Randomized Controlled Trial Comparative Study Clinical TrialPostoperative epidural morphine, but not epidural bupivacaine, delays gastric emptying on the first day after cholecystectomy.
Gastric emptying is delayed during the first days after abdominal surgery. Studies with volunteers have shown that epidural morphine delays gastric emptying but epidural analgesia with bupivacaine does not. The aim of this study was to evaluate whether these differences in healthy volunteers are also found after cholecystectomy when epidural morphine or epidural bupivacaine is used for postoperative pain relief. ⋯ Postoperative gastric emptying was significantly delayed after epidural analgesia with morphine compared to thoracic epidural bupivacaine. Compared to the control situation, epidural bupivacaine did not influence gastric emptying.

Though cervical paratracheal injections for the purpose of sympathetic block are customarily referred to as stellate ganglion blocks, there is no documentation of the actual site of local anesthetic action. The objective of this study is to test whether solution travels to the stellate ganglion during injections commonly used to anesthetize it. ⋯ The findings suggest that sympathetic neural block during stellate ganglion block may take place at sites other than the stellate ganglion.

Randomized Controlled Trial Comparative Study Clinical TrialAn evaluation of epidural bupivacaine with and without meperidine in labor.
One aim of epidural analgesia during childbirth is to provide satisfactory pain relief with minimal side effects. We hypothesized that a combination of opioid and local anesthetic would better achieve this aim than either drug alone. This study compared the efficacy and side effects of epidural meperidine and bupivacaine combined to those of meperidine and bupivacaine alone. ⋯ The low-dose combination of meperidine and bupivacaine used in this trial proved a satisfactory preparation for epidural administration during the early stages of labor.
