Postoperative sore throat and hoarseness are common and disturbing complications following endotracheal intubation, and women are more frequently affected by these symptoms. This study explores risk factors associated with postoperative sore throat and hoarseness in women following intubation. In this prospective cross-sectional study, 97 patients undergoing elective ear, nose, and throat surgery or plastic surgery were included. ⋯ Three variables were found to be significant risk factors for postoperative sore throat: age greater than 60 years (P = .01), the use of a throat pack (P = .04), and endotracheal tube No. 7.0 (size 7 mm; P = .02). The only risk factor found to be significantly associated with developing hoarseness was an endotracheal cuff pressure below 20 centimeters of water (P = .04). Larger studies are needed to confirm these risk factors.

Despite compelling evidence for the safety and efficacy of intrathecal hydromorphone, the use of this opioid intrathecally for the pain management of patients undergoing cesarean delivery has not been widely accepted. The purpose of this retrospective study was to compare the reported efficacy and safety of pain management in women who received intrathecal hydromorphone (100 microg) vs in women who received intrathecal fentanyl (25 microg) or a local anesthetic for their cesarean delivery. The author hypothesized that intrathecal hydromorphone because of its known pharmacodynamics would provide better postoperative analgesia within the first 24 hours after cesarean delivery. ⋯ Traditionally, intrathecal morphine was the opioid of choice for prolonged pain management during cesarean deliveries in which spinal anesthesia was selected. However, intrathecal hydromorphone was shown to be an effective and possibly even better substitute. Further research on intrathecal hydromorphone is needed.

Peripheral nerve blocks are common and effective means for anesthesia for limb surgery. The evaluation of the success of a peripheral blockade is based on the loss of sensation, with no objective means of detecting a successful block. The autonomic innervation to the upper extremity, which controls both the vascular tone and the activity of sweat glands, is supplied by nerve fibers accompanying the somatic nerve fibers. ⋯ The electrical resistance of the skin on the palmar aspect of the forearm was continuously recorded on the block arm and on the contralateral arm using a commercial skin resistance monitor. No statistically significant change in the electrical resistance of the skin was observed during 20 minutes after placement of the block. These results strongly suggest that the electrical resistance of the skin cannot be used to predict a successful infraclavicular block.

Placement of an epidural catheter in parturients can be challenging because the anatomic changes of pregnancy may make it difficult to palpate an ideal insertion point or detect loss of resistance. Preprocedural ultrasonography (U/S-P) is reported to facilitate placement of epidural catheters in parturients. ⋯ The purposes of this course are to describe the technique, systematically review the literature, and discuss techniques for integrating U/S-P into practice. It provides evidence demonstrating that U/S-P is a useful adjunct for placement of epidural catheters in obstetrical patients, especially patients with presumed "difficult backs" or obesity.

Clinical Trial
Implementation of an evidence-based extubation checklist to reduce extubation failure in patients with trauma: a pilot study.
This prospective, case-controlled observational study assessed whether an evidence-based extubation checklist would increase anesthesia providers' documentation of standardized extubation criteria and reduce the occurrence of preventable extubation failures in the early postoperative period. The sample consisted of 622 ASA Physical Status I to IV patients, aged 10 to 100 years but primarily adults, who underwent elective and emergency surgeries at a university-based adult trauma teaching hospital. Before the study, all anesthesia and postanesthesia care unit staff received an in-service on adherence to an evidence-based extubation checklist, followed by implementation of the checklist for 12 weeks. ⋯ Following use of the extubation checklist, documentation of patient readiness for extubation increased from 54% to 92.5%, and extubation failures decreased from 2.5 per month to 7.2 per month. This study confirmed that extubation failure occurred less frequently when the extubation checklist was used (P = .001, Fisher exact test). Study results indicate that an extubation checklist may positively influence provider documentation of evidence-based criteria for extubation and can reduce the occurrence of preventable extubation failures.
