Randomized Controlled Trial Comparative Study
A Randomized Control Trial of Bupivacaine and Fentanyl versus Fentanyl-only for Epidural Analgesia during the Second Stage of Labor.
Fentanyl-only epidural infusion shows no benefit over fentanyl/bupiv in respect to duration of labor, motor block, delivery, analgesia, or outcomes.

Randomized Controlled Trial
Transfusion Requirements in Surgical Oncology Patients: A Prospective, Randomized Controlled Trial.
The researchers found that in a cohort of 198 patients admitted to ICU after major abdominal cancer surgery, those subjected to a liberal blood transfusion threshold of < 9 g/dL experienced fewer major complications (NNT 6.2) than those subjected to a restrictive transfusion threshold (< 7 g/dL).

In 1997, the International Classification of Diseases (ICD), 9th Revision Clinical Modification (ICD-9) coding system introduced the code for malignant hyperthermia (MH) (995.86). The aim of this study was to estimate the accuracy of coding for MH in hospital discharge records. ⋯ Approximately one quarter of ICD-9 or ICD-10 coded MH diagnoses in hospital discharge records refer to incident MH episodes and an additional 47% to MH susceptibility (including personal history or family history). Information such as surgical procedure, anesthesia billing data, and dantrolene administration may aid in identifying incident MH cases among those with an ICD-9 or ICD-10 coded MH diagnosis in their hospital discharge records.

Recurrent nocturnal hypoxemia in obstructive sleep apnea enhances sympathetic function, decreases baroreceptor sensitivity, and weakens peripheral vascular responses to adrenergic signals. The authors hypothesized that the percentage of total sleep time spent at oxyhemoglobin saturation (SaO2) less than 90% and minimum nocturnal SaO2 on preoperative polysomnography are associated with decreased intraoperative mean arterial pressure. ⋯ Recurrent nocturnal hypoxemia in obstructive sleep apnea is not a risk marker for intraoperative hypotension.
