Review Randomized Controlled Trial Comparative Study Clinical Trial
Circumcision anesthesia: a study of nursing implications for dorsal penile nerve block.
To compare responses to circumcision between a group of unanesthetized newborn males and a group having dorsal penile nerve block (DPNB). ⋯ The unanesthetized subjects displayed stress reactions that have implications for nursing care.

Randomized Controlled Trial Comparative Study Clinical Trial[Pain therapy after thoracotomies--systemic patient-controlled analgesia (PCA) with opioid versus intercostal block and interpleural analgesia].
Both regional analgesia and systemic opioid therapy (e.g. PCA) are commonly used for pain relief following thoracic surgery. Many anaesthesiologists are reluctant to use thoracic epidural analgesia on general surgical wards. ⋯ Intercostal blocks and interpleural analgesia significantly reduce opioid demand following thoracotomy and are effective means of postoperative pain management. Nevertheless, in contrast to epidural analgesia, both methods have to be supplemented by, or combined with, systemic analgesics in most patients. On the other hand, compared to epidural analgesia, ICB and IPA are less invasive and easier to manage on general surgical wards.

Randomized Controlled Trial Clinical TrialTenoxicam does not enhance the spread of sensory block produced by intrathecal lidocaine.
Systemic opioids enhance the spread of spinal analgesia. This study was designed to determine whether i.v. tenoxicam, a nonsteroidal anti-inflammatory drug (NSAID), affects the spread of sensory block produced by lidocaine. Sixty patients undergoing transurethral procedures were randomly assigned in a double blind design to receive i.v. either 3 ml normal saline (N/S group, n = 20), or 150 micrograms fentanyl (F group, n = 20), or 40 mg tenoxicam (T group, n = 20), 20 minutes after spinal anesthesia. ⋯ The overall change in the level of sensory block 15 minutes after i.v. treatment was -4.6 +/- 6.3 cm in the N/S group, 2.4 +/- 6.0 cm in the F group, and -1.6 +/- 5.8 cm in the T group. The F group differed from the N/S group (P < 0.01). Intravenous administration of tenoxicam does not enhance the level of spinal analgesia produced by lidocaine.

Randomized Controlled Trial Clinical TrialDifferential sensory block after spinal bupivacaine in volunteers.
We performed this study to determine whether differential sensory block to touch, pinprick, and cold after spinal bupivacaine could be used to predict the dermatomal level of block to transcutaneous electrical stimulation (TES) equivalent to surgical stimulation, onset of tourniquet pain, or magnitude of hemodynamic depression. Eight subjects per group were randomized to receive 3.75, 7.5, or 11.25 mg of 0.75% bupivacaine with 8.25% dextrose in a double-blind fashion. Sensory block was assessed with touch, pinprick, cold, TES at T-12, L-2, S-1, and thigh tourniquet pain. ⋯ However, the extent of differential sensory block to touch, pinprick, and cold varied up to 10 dermatomes (2 SD) cephalad to block to TES and up to 7 dermatomes (2 SD) cephalad to the thigh tourniquet at the time of intolerable tourniquet pain. Sensory block to cold did not correlate with hemodynamic depression. Differential sensory block occurs after bupivacaine spinal anesthesia, but is a poor predictor for surgical anesthesia, tourniquet pain, and hemodynamic depression.
