Comparative Study Clinical Trial
[Assessment of postoperative pain using face scale judged by nurses: comparison between hepatectomy and esophagectomy].
The agreement between scores for observer-reported face scale (FS) and the self-reported visual analog scale (VAS) in postoperative pain assessment has not been compared for different types of surgery and for different times in the postoperative course. Five grade FS (1-5) judged by a nurse was compared with VAS (0-100 mm) reported by patients who had undergone hepatectomy (group H, n = 60) or esophageal cancer surgery by a thoracoabdominal procedure (group E, n = 50). Postoperative analgesia was mainly achieved by epidural morphine administration combined with lidocaine or bupivacaine in both groups. ⋯ A fair degree of agreement was found between VAS and FS scores in group H at ICU admission and one hour later (weighted kappa values = 0.29 and 0.28, respectively); on the other hand, good agreement between these two scores was found in group E thirty minutes and one hour after tracheal extubation (weighted kappa values = 0.67 and 0.62, respectively). Weighted kappa values decreased thereafter in group E, but did not change in group H over the postoperative course. We conclude that postoperative pain assessment based on facial expression is more useful early after extubation for patients who have undergone esophagectomy than for those who have undergone hepatectomy.

We report a patient in whom urinary retention as a transient neurologic symptoms (TNS) developed after accidental total spinal anesthesia with mepivacaine hydrochloride. Mepivacaine, an amide local anesthetic, has been used for spinal anesthesia and considered one of the best for spinal anesthesia for its low incidence of TNS. However, we suggest that TNS associated with mepivacaine might not be a rare complication in spinal anesthesia.

We reported anesthetic management combined with hypothermia for carotid endarterectomy under somatosensory evoked potential monitoring. Anesthesia was induced by propofol, fentanyl and ketamine, and maintained by infusion of propofol and ketamine and intermittent injections of fentanyl. Perioperative hypothermia was induced by gradually reducing the temperature of a circulating water mattress underneath the body to 15 degrees C. ⋯ No neurological deficits were observed following recovery from anesthesia. Total intravenous anesthesia with propofol, fentanyl and ketamine may be useful for carotid endarterectomy under hypothermia and somatosensory evoked potential monitoring. This method may provide neuronal protection against ischemia injuries induced by cross-clamping of the carotid artery.
