Case ReportsUse of a home positive airway pressure device during intraoperative monitored anesthesia care for outpatient surgery.
Perioperative positive airway pressure (PAP) is recommended by the American Society of Anesthesiologists for patients with obstructive sleep apnea, but a readily available and personalized intraoperative delivery system does not exist. We present the successful use of a patient's own nasal PAP machine in the operating room during outpatient foot surgery which required addition of a straight adaptor for oxygen delivery and careful positioning of the gas sampling line to permit end-tidal carbox dioxide monitoring. Home PAP machines may provide a potential alternative to more invasive methods of airway management for patients with obstructive sleep apnea under moderate sedation.

Effect of interleukin 6 -174G>C gene polymorphism on opioid requirements after total hip replacement.
In recent years, increasing attention has been paid to the contribution of genetic factors to variability in patient pain threshold and the efficacy of pain management. One of the genes implicated in pain pathology and treatment response is interleukin 6 (IL6). The aim of the present study was to evaluate the association between IL6 (rs1800795: -174G>C) and opioid requirements in patients after total hip replacement (THR). ⋯ The presence of the G allele IL6 gene (-174G>C) polymorphism was found to be an independent factor predisposing to a higher dose and more frequent administration of opioids in the first days after total hip replacement.

Difficult airway management resources and capnography use in Japanese intensive care units: a nationwide cross-sectional study.
The availability of difficult airway management (DAM) resources and the extent of capnometry use in Japanese intensive care units (ICUs) remained unclear. The purpose of this study was to clarify whether: (1) DAM resources were adequate, and (2) capnometry was routinely applied in Japanese ICUs. ⋯ In Japanese ICUs, SGAs and dedicated DAM carts were less available, and capnometry was not universally applied either to confirm tube placement, or for continuous monitoring of ventilated patients. Our study revealed areas in need of improvement.

Preoperative serum lactate cannot predict in-hospital mortality after decompressive craniectomy in traumatic brain injury.
Despite the utility of serum lactate for predicting clinical courses, little information is available on the topic after decompressive craniectomy. This study was conducted to determine the ability of perioperative serum lactate levels to predict in-hospital mortality in traumatic brain-injury patients who received emergency or urgent decompressive craniectomy. ⋯ Preoperative lactate level is not an independent predictor of in-hospital mortality after decompressive craniectomy in traumatic brain-injury patients.

Case ReportsManagement of three cardiogenic pulmonary edemas occurring in a patient scheduled for left ventricular assist device implantation: indicators for determining left ventricular assist device pump speed.
A male patient with Marfan syndrome underwent aortic root replacement and developed left ventricular (LV) failure. Four years later, he underwent aortic arch and aortic valve replacement. Thereafter, his LV failure progressed, and cardiogenic pulmonary edema (CPE) appeared, which we treated with extracorporeal LV assist device (LVAD) placement. ⋯ Additionally, systolic pulmonary artery pressure (sPAP), left atrial diameter (LAD), RV end-diastolic diameter (RVEDD) and estimated RV systolic pressure (esRVP) changed with PAWP changes. In this patient, LV failure and hyperdynamic RV caused the CPEs, which we treated by adjusting the LVAD output to the RV output. Determining LVAD output, RV function and LV end-diastolic diameter are typically referred, and PAWP, LAD, RVEDD, and sPAP could be also referred.
