Case Reports Randomized Controlled Trial Clinical TrialDirection of catheter insertion and incidence of paresthesias and failure rate in continuous epidural anesthesia: a comparison of cephalad and caudad catheter insertion.
Paresthesias and unblocked segments during continuous epidural anesthesia--sometimes leading to higher doses of local anesthetics--can increase the risk of this technique. A cephalad insertion of the epidural catheter might decrease the incidence of these problems, but this has not been evaluated before in a controlled study. ⋯ Our results support the contention that the catheter should be directed cephalad during insertion for continuous epidural anesthesia.

Randomized Controlled Trial Clinical TrialLack of effect of sphenopalatine ganglion block with intranasal lidocaine on submaximal effort tourniquet test pain.
The present study examined whether sphenopalatine ganglion block (SPGB) causes a reduction in the response to acute nociceptive input that may account for the SPGB-induced relief reported by many patients with chronic pain. ⋯ SPGB does not lessen acute extremity pain to a significant degree and is not in and of itself an effective means of analgesia for acute pain. Its potential impact on nociceptive stimuli that elicit a "strong sensation" (i.e., a score of 5-7 in the present study) should be evaluated in hyperpathic pain states and in states with exaggerated aversive responses.

Comparative StudyPlasma alcohol concentrations after celiac plexus block in gastric and pancreatic cancer.
The objective of this study was to compare the plasma alcohol concentrations after celiac plexus block in different types of cancer. The authors studied the consecutive changes of plasma alcohol concentrations after celiac plexus block in a gastric cancer group (group 1, n = 6) and a pancreatic cancer group (group 2, n = 5). ⋯ Plasma alcohol concentrations after celiac plexus block showed different patterns according to the site of cancer and the type of operation performed.

Randomized Controlled Trial Comparative Study Clinical TrialThoracic versus lumbar administration of epidural morphine for postoperative analgesia after thoracotomy.
The purpose of this study was to compare the effects of thoracic and lumbar epidural morphine on pulmonary function and analgesia after thoracotomy for pulmonary resection. ⋯ The authors conclude that thoracic epidural morphine administration in patients after thoracotomy results in decreased morphine requirements and the same degree of analgesia as does lumbar administration.
