Randomized Controlled Trial Comparative Study Clinical TrialComparison of postanesthetic sequelae after clinical use of 27-gauge cutting and noncutting spinal needles.
The tips of the bevels of thin spinal needles may be easily damaged by bony contact during puncture attempts. In this respect and also because they are less traumatic by design, noncutting, pencil-point-tip needles may be beneficial. A prospective clinical comparison of postanesthetic effects of the use of 27G Quincke-type and pencil-point spinal needles was therefore performed. ⋯ Postanesthetic sequelae, including postdural puncture headache (overall incidence 2.5%), were not related to the shape of the spinal needles or to the damage of the Quincke-type needles.

Randomized Controlled Trial Clinical TrialPostoperative analgesia and antiemetic efficacy after intrathecal neostigmine in patients undergoing abdominal hysterectomy during spinal anesthesia.
Postoperative analgesia and antiemetic efficacy after intrathecal neostigmine were investigated in a randomized, double-blind, placebo-controlled trial of 100 patients undergoing abdominal hysterectomy. ⋯ Intrathecal neostigmine (100 microg) was ineffective for postoperative analgesia after abdominal hysterectomy due to side effects of nausea and vomiting.

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.

Spinal anesthesia is used for ambulatory surgical procedures. We provide an overview of the use of local anesthetics, use of continuous techniques, and use of adjuncts for optimization of spinal anesthesia for ambulatory surgery. ⋯ Ambulatory spinal anesthesia may be optimized by selection of dose, concentration, and baricity of local anesthetic. Use of a continuous technique or an intrathecal adjunct may also be valuable means to optimize spinal anesthesia for ambulatory surgery.

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.
