ReviewDoes epidural analgesia during labor affect the incidence of cesarean delivery?
There is substantial evidence that there is an increased incidence of cesarean delivery among patients who receive epidural analgesia during labor. The controversy as to whether there is a causal relationship between epidural analgesia and cesarean delivery. Two prospective, randomized studies suggest that epidural analgesia may increase the incidence of operative delivery in laboring women. ⋯ It is important to consider the impact of epidural analgesia on the total population of obstetric patients. Maternal-fetal factors and obstetric management, not epidural analgesia, are the most important determinants of the cesarean delivery rate. Finally, physicians should remember that pain relief is itself a worthy goal.

Randomized Controlled Trial Clinical TrialA low-dose hypobaric bupivacaine spinal anesthesia for knee arthroscopies.
Ambulatory surgery requires anesthesia methods that allow rapid recovery and safe discharge of the patient. Spinal anesthesia is easy and quick to perform, and the use of noncutting small gauge needles reduces the occurrence of postdural puncture headache. For minimal hemodynamic consequences and faster recovery and discharge it would be optimal to limit the spread of spinal anesthesia only to the area which is necessary for surgery. In this study, the possibility in achieving unilateral spinal anesthesia with 0.18% hypobaric bupivacaine was studied. ⋯ Approximately three and a half milliliters hypobaric 0.18% bupivacaine (6.12 mg) provides a predominantly unilateral spinal block. Thirty minutes spent in the lateral position does not provide benefits over 20 minutes. The main advantages of our method are the hemodynamic stability and the patient satisfaction.

Randomized Controlled Trial Comparative Study Clinical TrialIncidence of genitofemoral nerve block during lumbar sympathetic block: comparison of two lumbar injection sites.
Genitofemoral nerve (GFN) block is a known side effect of a lumbar sympathetic block (LSB), although the incidence has not been well documented. Furthermore, genitofemoral neuralgia can occur following neurolytic LSB. Because the level at which the GFN exits the psoas sheath varies, this study was designed to identify differences in the incidence of GFN block following LSB at the level of the second versus the fourth lumbar vertebrae. ⋯ The GFN is less likely to be blocked when the LSB is performed near the second lumbar vertebra as compared with the fourth lumbar vertebra.

Randomized Controlled Trial Clinical TrialSingle-shot spinal anesthesia with small doses of bupivacaine.
The potential risks of spinal lidocaine have generated interest in an alternative local anesthetic solution. Features of anesthetic block were therefore assessed in a double-blind randomized prospective study following administration of spinal bupivacaine in small doses. ⋯ Hyperbaric bupivacaine 6-8 mg provides a suitable alternative to spinal lidocaine for surgical procedures of short duration.
