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 Comparative Study Clinical TrialSubarachnoid sufentanil versus lidocaine spinal anesthesia for extracorporeal shock wave lithotripsy.
Anesthetic techniques that reduce the time required for postoperative care can significantly reduce the cost of procedures. This study was designed to discover whether the use of subarachnoid sufentanil for extracorporeal shock wave lithotripsy (ESWL) would enable patients to be discharged more rapidly following surgery as compared with subarachnoid lidocaine, while providing equivalent efficacy. ⋯ Subarachnoid sufentanil provides acceptable analgesia for ESWL and offers the advantages of more rapid discharge for female patients and better hemodynamic stability as compared with lidocaine spinal anesthesia.

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.

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 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.
