Loss of sensation to pinprick and cold are commonly used to test the extent of epidural anesthesia. To see what difference exists between the level of epidural block determined by various sensory modalities, we performed this study in ten volunteers using epidural anesthesia with plain 3% chloroprocaine hydrochloride. ⋯ This study establishes the existence of a differential epidural anesthesia during high thoracic block with chloroprocaine and suggests that the intensity of block diminishes as distance from site of injection increases.

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.

Randomized Controlled Trial Comparative Study Clinical TrialContinuous pleural infusion of bupivacaine offers better postoperative pain relief than does bolus administration.
To determine whether continuous pleural analgesia offers better postoperative pain relief than does bolus administration in postcholecystectomy patients. ⋯ Continuous pleural analgesia offers better postoperative pain relief than does bolus administration. Pneumothorax was observed in two patients during the study.

Randomized Controlled Trial Clinical TrialEffect of subarachnoid morphine on the incidence of spinal headache.
The addition of fentanyl to hyperbaric local anesthetics has been shown to reduce the incidence of post dural puncture headache in the obstetric patient. This study was undertaken to evaluate the effects of subarachnoid morphine on the incidence of headache. ⋯ It is concluded from our study that subarachnoid morphine did not decrease the incidence of post dural puncture headache in the obstetric patient.

Comparative StudySprotte needle for obstetric anesthesia: decreased incidence of post dural puncture headache.
Reports have emphasized the importance of spinal needle tip configuration in the development of post dural puncture headache (PDPH). ⋯ Our data indicate that the Sprotte spinal needle, with its non-cutting tip, results in a significantly lower (p less than 0.05) incidence of PDPH than Quincke cutting-tip needles of smaller gauge.
