Case Reports
Real-time measurement of blood pressure with Nexfin in a patient with thalidomide-related phocomelia.
We report the novel application of photoplethysmographic technology with the Nexfin HD monitor for real-time measurement of blood pressure (BP) in a patient with tetraamelia. The patient was a 58-year-old man with tetraamelia secondary to thalidomide exposure in utero, who presented for surgical excision of a maxillary schwannoma. Because difficulty of cuff use on rudimentary limbs and failure to gain invasive arterial access due to abnormalities of limb vasculature, this population is known to pose some unique challenges for BP measurement. Nexfin may offer an alternative noninvasive method to detect BP in patients with phocomelia during the perioperative period.

Back injuries are a highly reported category of occupational injury in the health care setting. The daily clinical activities of an anesthesia provider, including lifting, pushing stretchers, transferring patients, and bending for procedures, are risk factors for developing low back pain. The purpose of this study is to investigate the prevalence of work related low back pain in anesthesia providers. ⋯ Nearly half of all anesthesia providers sampled suffer from low back pain subjectively attributed to their clinical practice. This leads to changes in work flow and missed days of work. The results of this study suggest a deficiency in the effectiveness of anesthesia training programs in teaching proper techniques to prevent musculoskeletal injuries.

Comparative Study Observational Study
Effect of thoracic epidural analgesia on recovery of bowel function after major upper abdominal surgery.
We investigated whether thoracic epidural analgesia (TEA) shortens the first gas-out time compared to intravenous patient-controlled analgesia (iv-PCA) and promotes earlier discharge after major upper abdominal surgery. ⋯ TEA with a regimen of hydromorphone (8 μg/mL) added to 0.15% ropivacaine did not provide earlier gas-out compared to that of iv-PCA in patients who underwent major upper abdominal surgery.

Observational Study
Noninvasive ventilation during spontaneous breathing anesthesia: an observational study using electrical impedance tomography.
To assess the effects of noninvasive ventilation (NIV) during spontaneous breathing anesthesia on functional residual capacity and ventilation distribution. ⋯ This study showed that NIV application in pressure support mode during spontaneous breathing anesthesia increased functional residual capacity. Other studies are needed to evaluate the clinical impact of this technique during anesthesia, especially in patients with poor respiratory conditions.

Two types of bradykinin-mediated angioedema, hereditary angioedema (HAE) and acquired angioedema (AAE), result from deficiency or dysfunction of C1 esterase inhibitor, leading to an overproduction of bradykinin, which can lead to vascular permeability and life-threatening angioedema of the airway. The objective of this study was to review perioperative outcomes in a series of patients with HAE and AAE and to review current knowledge about anesthetic complications in patients with HAE or AAE. ⋯ Life-threatening episodes of angioedema of the airway occur infrequently, but they can occur in patients who received pretreatment and in patients who have previously undergone anesthesia uneventfully. Anesthesiologists must be ready to emergently manage a difficult airway and must be familiar with recommendations provided in consensus guidelines for the treatment of HAE and AAE patients.
