Objective Model Using Only Gender, Age and Medication List Predicts In-hospital Morbidity After Elective Surgery
(Abstracted from Br J Anaesth, 118(4):544–550, 2017)
Using a retrospective single-center database study, a risk-evaluation tool for elective surgery was devised. This neutral prognostic tool of in-hospital postoperative morbidity used commonly available data, such as sex, age, and list of medications to assess risk without depending on laboratory tests or complex diagnoses.

Implementing a Statistical Model for Protamine Titration: Effects on Coagulation in Cardiac Surgical Patients
(Abstracted from J Cardiothorac Vasc Anesth, 31:516–21, 2017)
Using a fixed protamine-heparin dose (1:1) is the most commonly used method of protamine dosing in cardiopulmonary bypass patients to reverse the effects of heparin. The hemostasis management system (HMS Plus; Medtronic, Minneapolis, Minn) is an accepted alternate point-of-care device to calculate protamine dosing. (Source: Survey of Anesthesiology)

Trends in Tramadol: Pharmacology, Metabolism, and Misuse
(Abstracted from Anesth Analg, 124(1):44–51, 2017)
The purpose of this review was to examine the literature published over the period January 1980 to January 2016 regarding the use of tramadol for treatment of moderate to moderately severe chronic pain. Tramadol is a synthetic opioid medication with monoaminergic actions and a mechanism similar to serotonin-norepinephrine reuptake inhibitors. (Source: Survey of Anesthesiology)

Monkey in the Middle: Translational Studies of Pediatric Anesthetic Exposure
(Abstracted from Anesthesiology, 126(1):6–8, 2017)
Preclinical animal studies have resulted in retrospective and prospective studies in humans regarding the safety of pediatric anesthesia. The possibility of adverse neurocognitive outcomes associated with repeated or prolonged pediatric anesthesia is worrisome. (Source: Survey of Anesthesiology)

Isoflurane Anesthesia Has Long-term Consequences on Motor and Behavioral Development in Infant Rhesus Macaques
(Abstracted from Anesthesiology, 126(1):74–84, 2017)
The purpose of this trial was to examine isoflurane exposure in children utilizing the nonhuman primate (NHP) model. This translational research is important because there is significant experimental evidence that anesthetic exposure correlates with neural cell injury and neuron death in the developing brain.

Paediatric Emergence Delirium: A Comprehensive Review and Interpretation of the Literature
This article considers the evolution of emergence delirium (ED) and emergence agitation since it was first identified in the 1960s to assess present and future trends in identification, treatment, and prognostic value. There is a need for well-designed large prospective studies to assess ED risk factors and eliminate confounders as well as a need for standardized screening, evaluation tools, and data sharing in order to easily compare outcomes for researchers of pediatric ED (characterized by crying, sobbing, thrashing about, and disorientation following anesthesia).

Anesthetic and Obstetrical Factors Associated With the Effectiveness of Epidural Analgesia for Labor Pain Relief: An Observational Population-Based Study
(Abstracted from Reg Anesth Pain Med, 42(1):109–116, 2017)
Epidural analgesia is considered the criterion standard for pain relief during labor because of its high rate of maternal satisfaction and minimal adverse effects for both mother and child. However, pain relief during labor is also a complex issue, and there continue to be efforts to improve epidural analgesia. (Source: Survey of Anesthesiology)

Vital Signs and Other Observations Used to Detect Deterioration in Pregnant Women: An Analysis of Vital Sign Charts in Consultant-Led UK Maternity Units
(Abstracted from Int J Obstet Anesth, 30:44–51, 2017)
The main objective of this study was to assess early warning charts routinely used in the United Kingdom and the Channel Islands' consultant-led maternity units so as to determine the maternal vital sign values deemed normal in their obstetric early warning systems (ObsEWS), as well as identify the triggers and protocols for escalated care.

Anesthetic Considerations for Labor and Delivery in Women With Cerebrospinal Fluid Shunts
(Abstracted from Int J Obstet Anesth, 30:23–29, 2017)
The main objective of this literature review was to assess anesthetic techniques and complications associated with pregnant women with cerebrospinal fluid (CSF) shunts. Hydrocephalus, generally associated with abnormal physiology of CSF production or outflow, has multiple developmental and acquired causes. (Source: Survey of Anesthesiology)

Anaesthesia for Abnormally Invasive Placenta: A Single-Institution Case Series
(Abstracted from Int J Obstet Anesth, 30:10–15, 2017)
The purpose of this retrospective study is to present details of anesthetic management and outcomes for abnormally invasive placenta (AIP) with data over a 5-year period (January 2011–2016) from the John Radcliffe Hospital, tertiary-referral maternity unit in Oxford, United Kingdom. Cases of AIP were identified using the standard International Classification of Diseases, 10th Revision codes for placenta accreta, placenta increta, and placenta percreta (O43.2: morbidly adherent placenta).

The Effect of Melatonin on Early Postoperative Cognitive Decline in Elderly Patients Undergoing Hip Arthroplasty: A Randomized Controlled Trial
(Abstracted from J Clin Anesth, 39:77–81, 2017)
Postoperative cognitive decline (POCD) is a common complication following surgery, especially in elderly patients (aged>60 years). Overall sleep loss and sleep fragmentation have been known to negatively impact cognitive performance, thus emphasizing the need to improve postoperative sleep quality to ameliorate POCD.

The Effect of Desflurane Versus Propofol Anesthesia on Postoperative Delirium in Elderly Obese Patients Undergoing Total Knee Replacement: A Randomized, Controlled, Double-blinded Clinical Trial
(Abstracted from J Clin Anesth, 39:17–22, 2017)
The incidence of surgical procedures such as total knee arthroplasty (TKA) is high among elderly patients older than 65 years. Postoperative delirium is common in this age group as increasing age contributes to cognitive decline and prolonged recovery time from anesthesia. (Source: Survey of Anesthesiology)

Effect of Propofol, Sevoflurane, and Isoflurane on Postoperative Cognitive Dysfunction Following Laparoscopic Cholecystectomy in Elderly Patients: A Randomized Controlled Trial
(Abstracted from J Clin Anesth, 38:165–171, 2017)
Postoperative cognitive dysfunction (POCD) caused by surgical trauma and general anesthetics results in mortality and morbidity in surgical patients, especially the elderly (severe in aged>60 years). This randomized, double-blind clinical trial aimed to compare the incidence of POCD in elderly surgical patients receiving different anesthetics (propofol, sevoflurane, or isoflurane) and to identify potential biomarkers of POCD in elderly patients.
