December Is Coming: A Time Trend Analysis of Monthly Variation in Adult Elective Anesthesia Caseload across Florida and Texas Locations of a Large Multistate Practice.

Background: Anesthesia staffing models rely on predictable surgical case volumes. Previous studies have found no relationship between month of the year and surgical volume. However, seasonal events and greater use of high-deductible health insurance plans may cause U.

Factors Affecting Patient Satisfaction With Their Anesthesiologist: An Analysis of 51,676 Surveys From a Large Multihospital Practice.

Background: An increasing focus of health care quality is the assessment of patient-reported outcomes, including satisfaction. Because anesthesia care occurs in the context of perioperative surgical care, direct associations between anesthetic management and patient experience may be difficult to identify. We analyzed anesthesia-specific patient satisfaction survey data from a large private practice group to identify patient, procedure, and anesthetic-specific predictors of patient satisfaction with their anesthesiologist, measured via responses to a validated patient satisfaction survey instrument.

Advances in awareness monitoring technologies.

Purpose Of Review: Initial studies suggested that the use of processed electroencephalogram technology could significantly decrease the incidence of unintended intraoperative awareness events during general anesthesia. Subsequent work has cast doubts on these findings. This review will examine the current state of awareness monitoring.

Amnesia of the Operating Room in the B-Unaware and BAG-RECALL Clinical Trials.

Background: Patient memories of the operating room (OR) may serve as the informational basis for assessing satisfaction with individual anesthesiologists. Furthermore, the provision of clinically important information may assume that perioperative memories are retained. Studies assessing the extent of perioperative amnesia and factors associated with perioperative amnesia are sparse.

Corneal abrasion in hysterectomy and prostatectomy: role of laparoscopic and robotic assistance.

Background: Radical prostatectomy (RP) is most commonly performed laparoscopically with a robot (robotic-assisted laparoscopic radical prostatectomy, R/PROST). Hysterectomy, which may be open hysterectomy (O/HYST) or laparoscopic hysterectomy (L/HYST), has been increasingly frequently done via robot (R/HYST). Small case series suggest increased corneal abrasions (CAs) with less invasive techniques.

The relationship between competition and quality in procedural cardiac care.

Background: Anesthesiologists are frequently involved in efforts to meet perioperative quality metrics. The degree to which hospitals compete on publicly reported quality measures, however, is unclear. We hypothesized that hospitals in more competitive environments would be more likely to compete on quality and thus perform better on such measures.

Increased risk of intraoperative awareness in patients with a history of awareness.

Background: Patients with a history of intraoperative awareness with explicit recall (AWR) are hypothesized to be at higher risk for AWR than the general surgical population. In this study, the authors assessed whether patients with a history of AWR (1) are actually at higher risk for AWR; (2) receive different anesthetic management; and (3) are relatively resistant to the hypnotic actions of volatile anesthetics.

Methods: Patients with a history of AWR and matched controls from three randomized clinical trials investigating prevention of AWR were compared for relative risk of AWR.

The effect of propofol-remifentanil anesthesia on selected seizure quality indices in electroconvulsive therapy.

Background: Use of a short-acting opiate to potentiate anesthetic induction agents has been shown to increase seizure duration in electroconvulsive therapy (ECT), but little is known of the effect of this combination on indices of seizure quality.

Objective: To determine whether anesthetic modality affects commonly provided indices of seizure quality.

Methods: Twenty-five subjects were given propofol 2 mg/kg body weight for their first ECT session, at which time seizure threshold was titrated.

The limited value of sequencing cases based on their probability of cancellation.

Background: Case cancellations on the day of surgery reduce operating room (OR) and anesthesia group productivity. One strategy to reduce the impact of case cancellations on productivity is to assign high-risk cases to start last in the OR workday. To evaluate the utility of this intervention, we used a database of canceled cases to model the process of identifying high-risk cases and resequencing them to be the surgeons' last cases of the day.

Relationship between anesthetic depth and venous oxygen saturation during cardiopulmonary bypass.

Background: During cardiopulmonary bypass, mixed venous oxygen saturation (Svo2) is frequently measured to assess circulatory adequacy. Fluctuations in Svo2 not related to patient movement or inadequate oxygen delivery have been attributed clinically to increased cerebral oxygen consumption due to "light" anesthesia. To evaluate the relationship between anesthetic depth and Svo2, we prospectively measured bispectral index (BIS) and Svo2 values in patients undergoing cardiac surgery with cardiopulmonary bypass.

A novel classification instrument for intraoperative awareness events.

Background: Intraoperative awareness with explicit recall occurs in approximately 1-2 cases per 1000. Given the rarity of the event, a better understanding of awareness and its sequelae will likely require the compilation of data from numerous studies. As such, a standard description and expression of awareness events would be of value.

Prevention of awareness during general anesthesia.

Awareness during general anesthesia with subsequent explicit recall is a serious and frequently preventable problem that is gaining attention from clinicians and patients alike. Cost-effective interventions that increase vigilance should be implemented to decrease the likelihood of this complication.

Electroconvulsive therapy in a pediatric patient with malignant catatonia and paraneoplastic limbic encephalitis.

Paraneoplastic limbic encephalitis is a rare disorder that can cause memory loss, confusion, personality change, cognitive dysfunction, and psychosis. We present a case of an 11-year-old girl who was successfully treated with electroconvulsive therapy for a catatonic state associated with paraneoplastic limbic encephalitis caused by an ovarian teratoma.

Preoperative clinic visits reduce operating room cancellations and delays.

Background: Anesthesiologist-directed preoperative medicine clinics are used to prepare patients for the administration of anesthesia and surgery. Studies have shown that such a clinic reduces preoperative testing and consults, but few studies have examined the impact of the clinic on the day of surgery. The authors tested whether a visit to an anesthesia preoperative medicine clinic (APMC) would reduce day-of-surgery case cancellations and/or case delays.
