Performance characteristics and validation of the Opioid-Related Symptom Distress Scale for evaluation of analgesic side effects after orthopedic surgery.
The Opioid-Related Symptom Distress Scale (ORSDS) is a 4-point scale that evaluates 3 symptom distress dimensions (frequency, severity, bothersomeness) for 12 symptoms. The symptom-specific ORSDS is the average of the 3 symptom distress dimensions. The composite ORSDS is the average of 12 symptom-specific scores. The ORSDS was validated for outpatient laparoscopic cholecystectomy (under general anesthesia) by assessment of internal consistency, content validity, construct validity, principal components analysis, known group validity, responsiveness, and opioid dose dependency. Additional validation studies were suggested. We investigated performance characteristics and validity of the ORSDS for postoperative analgesia after 4 types of anesthetic and analgesic regimens. ⋯ Validity of the ORSDS was supported by predetermined validation criteria, including measures of internal consistency, content validity, construct validity, principal components analysis, known group validity, responsiveness, and correlation with opioid intake. The ORSDS is a valid tool for assessment of opioid side effects after orthopedic surgery, and can be used in clinical trials involving a wide variety of anesthetic and analgesic regimens.

A case series of the anesthetic management of parturients with surgically repaired tetralogy of Fallot.
Most case reports of pregnancies after surgical repair of tetralogy of Fallot have focused on cardiovascular and obstetric concerns, with relatively few authors focusing on specific intrapartum and postpartum anesthetic management strategies. ⋯ Pregnancy outcomes for patients with repaired tetralogy of Fallot were found to be generally favorable. All patients undergoing a trial of labor or cesarean delivery had neuraxial analgesia or anesthesia. Recognition and management of congestive heart failure was necessary in 19% of deliveries.

Hyperglycemia during craniotomy for adult traumatic brain injury.
Hyperglycemia after traumatic brain injury (TBI) is associated with poor outcome, but previous studies have not addressed intraoperative hyperglycemia in adult TBI. In this study, we examined glucose value variability and risk factors for hyperglycemia during craniotomy in adults with TBI. ⋯ Intraoperative hyperglycemia was common in adults undergoing urgent/emergent craniotomy for TBI and was predicted by severe TBI, the presence of subdural hematoma, preoperative hyperglycemia, and age ≥65 years. However, there was significant variability in intraoperative glucose values.

Forced needle advancement during needle-nerve contact in a porcine model: histological outcome.
In this study, we determined whether needle advancement during needle-nerve contact (forced needle-nerve contact) is associated with a higher risk of nerve injury compared with needle-nerve contact without needle advancement (nonforced needle-nerve contact). ⋯ The severity of structural nerve injury after needle-nerve contact was directly related to force exposure via needle advancement.
