Although the analgesic effects of ether were conclusively established during a series of public demonstrations of anesthesia at Massachusetts General Hospital in 1846, ether anesthesia was neither immediately nor universally introduced into practice. Betsey Magoun, the fourth patient undergoing surgery under anesthesia at the hospital, suffered life-threatening hypoxia and respiratory complications. Severe intraoperative problems witnessed by large audience may have contributed to the cautious introduction of anesthesia into routine practice.

Purpose Of Review: Despite a very low individual prevalence, rare or orphan diseases are estimated to collectively affect as much as 6-8% of the general population. These diseases provide a challenge to anesthetic delivery because of the lack of evidence to guide optimal management.

Recent Findings: The expansion of information technology has made facts about individual orphan diseases easier to find.

Background: The details of the public demonstration of the effects of ether that initiated the modern era of surgery and anesthesia are often misreported. Existing published transcripts of the clinical records are incomplete or inaccurate.

Methods: The patient notes of Gilbert Abbott were photographed, transcribed, and reviewed.

Background: The health care systems of low-income countries have severely limited capacity to treat surgical diseases and conditions. There is limited information about which hospital mortality outcomes are suitable metrics in these settings.

Methods: We did a 1-year observational cohort study of patient admissions to the Surgery and the Obstetrics and Gynecology departments and of newborns delivered at a Ugandan secondary referral hospital.

The career of Dr Charles J. Coté covered a period of major advances in pediatric anesthesia patient safety. Dr Coté (1946 --), Professor Emeritus in Anaesthesia at Harvard Medical School, helped develop pediatric sedation guidelines, conducted influential clinical research, edited a major textbook, and promoted pediatric anesthesia training fellowships in low- and middle-income countries.

The career of Dr Nishan Goudsouzian spanned half a century of pediatric anesthesia. His 50 years saw seminal contributions to the use of neuromuscular blocking agents in children, the development of proton beam therapy and magnetic resonance imaging for pediatric cancer, the introduction of the laryngeal mask airway, an explosion in the volume and depth of knowledge about pediatric anesthesia, the expansion of formal training in pediatric anesthesia, and the widening of academic efforts to improve anesthetic care for children worldwide. Based on interviews with Dr Goudsouzian, this article reviews the contributions of this Robert M.

Patients with autism spectrum disorder (ASD) often require sedation or general anesthesia. ASD is thought to arise from deficits in GABAergic signaling leading to abnormal neurodevelopment. We sought to investigate differences in how ASD patients respond to the GABAergic drug propofol by comparing the propofol-induced electroencephalogram (EEG) of ASD and neurotypical (NT) patients.

Background: In adults, frontal electroencephalogram patterns observed during propofol-induced unconsciousness consist of slow oscillations (0.1 to 1 Hz) and coherent alpha oscillations (8 to 13 Hz). Given that the nervous system undergoes significant changes during development, anesthesia-induced electroencephalogram oscillations in children may differ from those observed in adults.

Background: Despite increasing antimicrobial resistance globally, data are lacking on prevalence and factors associated with Staphylococcus aureus (SA) and MRSA carriage in resource-limited settings.

Objectives: To determine the prevalence of SA and MRSA nasal carriage and factors associated with carriage among Ugandan regional referral hospital patients.

Methods: We enrolled a cross-section of 500 adults, sampling anterior nares for SA and MRSA carriage using Cepheid Xpert SA Nasal Complete.

Background: We describe delivery and outcomes of critical care at Mbarara Regional Referral Hospital, a Ugandan secondary referral hospital serving a large, widely dispersed rural population.

Methods: Retrospective observational study of ICU admissions was performed from January 2008 to December 2011.

Results: Of 431 admissions, 239 (55.

Although Ernest Shackleton's Endurance Antarctic expedition of 1914 to 1916 is a famous epic of survival, the medical achievements of the two expedition doctors have received little formal examination. Marooned on Elephant Island after the expedition ship sank, Drs. Macklin and McIlroy administered a chloroform anesthetic to crew member Perce Blackborow to amputate his frostbitten toes.

Background: Transversus abdominis plane (TAP) block provides 12-24 h of analgesia to the parietal peritoneum and abdominal wall, and are best used combined with oral or intravenous medications. Despite ease of use, a large margin of safety, and a high success rate, TAP blocks remain under used in settings where patients could most benefit from their use. Previous studies have used oral or intravenous narcotics for supplementation.

Background: Communication failures are a significant cause of preventable medical errors, and poor-quality handoffs are associated with adverse events. We developed and implemented a simple checklist to improve communication during intraoperative transfer of patient care.

Methods: A prospective observational assessment was performed to compare relay and retention of critical patient information between the outgoing and incoming anesthesiologist before and after introduction of an electronic handoff checklist.

Pediatric patients face multiple reconstructive surgeries to reestablish function and aesthetics postburn injury. Often, the site of the harvested graft for these reconstructions is reported to be the most painful part of the procedure and a common reason for deferring these reconstructive procedures. This study in pediatric burn patients undergoing reconstructive procedures examined the analgesia response to local anesthetic infiltration versus either a single ultrasound-guided regional nerve block of the lateral femoral cutaneous nerve (LFCN) or a fascia iliaca compartment block with catheter placement and continuous infusion.

Background: Electrical Cardiometry(™) (EC) estimates cardiac parameters by measuring changes in thoracic electrical bioimpedance during the cardiac cycle. The ICON(®), using four electrocardiogram electrodes (EKG), estimates the maximum rate of change of impedance to peak aortic blood acceleration (based on the premise that red blood cells change from random orientation during diastole (high impedance) to an aligned state during systole (low impedance)).

Objective: To determine whether continuous cardiac output (CO) data provide additional information to current anesthesia monitors that is useful to practitioners.

Background: Although children with sickle cell disease often undergo surgery, there are limited current epidemiological data for this pediatric population. We performed a database analysis to estimate population characteristics, surgical procedures, and perioperative outcomes in this population.

Methods: We queried the Nationwide Inpatient Sample Database from 2000 to 2010 for discharges pertaining to patients <18 years of age having a diagnosis of sickle cell disease who underwent 1 or more surgical procedures during that admission.

Dr. John J. 'Jack' Downes (1930-), the anesthesiologist-in-chief at The Children's Hospital of Philadelphia (1972-1996), has made numerous contributions to pediatric anesthesia and critical care medicine through a broad spectrum of research on chronic respiratory failure, status asthmaticus, postoperative risks of apnea in premature infants, and home-assisted mechanical ventilation.
