The rising tide of opioid use and abuse: the role of the anesthesiologist

Opioid use has risen dramatically in the past three decades. In the USA, opioid overdose has become a leading cause of unintentional death, surpassing motor vehicle accidents. A patient’s first exposure to opioids may be during the perioperative period, a time where anesthesiologists have a significant role in pain management. Almost all patients in the USA receive opioids during...

Surgical specialty and preoperative medical consultation based on commercial health insurance claims

BackgroundSurgical patients are sometimes referred for preoperative evaluations by consultants in other medical specialties, although consultations are unnecessary for many patients, particularly for healthy patients undergoing low-risk surgeries. Surgical specialty has been shown to predict usage of preoperative consultations. However, evidence is generally limited regarding...

The evaluation of risk prediction models in predicting outcomes after bariatric surgery: a prospective observational cohort pilot study

BackgroundAs the prevalence of obesity is increasing, the number of patients requiring surgical intervention for obesity-related illness is also rising. The aim of this pilot study was to explore predictors of short-term morbidity and longer-term poor weight loss after bariatric surgery.MethodsThis was a single-centre prospective observational cohort pilot study in patients...

The sensitivity of the human thirst response to changes in plasma osmolality: a systematic review

Background Dehydration is highly prevalent and is associated with adverse cardiovascular and renal events. Clinical assessment of dehydration lacks sensitivity. Perhaps a patient’s thirst can provide an accurate guide to fluid therapy. This systematic review examines the sensitivity of thirst in responding to changes in plasma osmolality in participants of any age with no...

Impact of ASA score misclassification on NSQIP predicted mortality: a retrospective analysis

Background The ASA physical classification score has a major impact on the observed/expected (O/E) mortality ratio in the NSQIP General Vascular Mortality Model. The difference in predicted mortality is greatest between ASAs 3 and 4. We hypothesized under-classified ASA scores significantly affect the O/E mortality. Methods We conducted a retrospective review of NSQIP essential...

Immunonutrition within enhanced recovery after surgery (ERAS): an unresolved matter

Preoperative malnutrition because of poor oral intake significantly increases the risk of adverse events after surgery and leads to increased length of stay. While immunonutrition has been utilized in the non-ERAS setting, its utility in both minimally invasive surgery and ERAS pathway procedures remain poorly defined. There are at least ten meta-analyses regarding the assessment...

A systematic review and overview of health economic evaluations of emergency laparotomy

Background Little is known about the economic impact of emergency laparotomy (EL) surgery in healthcare systems around the world. The aim of this systematic review is to describe the primary resource utilisation, healthcare economic and societal costs of EL in adults in different countries. Methods MEDLINE, EMBASE, ISI Web of Knowledge, Cochrane Central Register Controlled Trials...

Comparison of risk-scoring systems in the prediction of outcome after liver resection

Background Risk prediction techniques commonly used in liver surgery include the American Society of Anesthesiologists (ASA) grading, Charlson Comorbidity Index (CCI) and cardiopulmonary exercise tests (CPET). This study compares the utility of these techniques along with the number of segments resected as predictive tools in liver surgery. Methods A review of a unit database of...

Association of postoperative nausea/vomiting and pain with breastfeeding success

Background Successful breastfeeding is a goal set forth by the World Health Organization to improve neonatal care. Increasingly, patients express the desire to breastfeed, and clinicians should facilitate successful breastfeeding. The primary aim of this study is to determine if postoperative nausea and vomiting (PONV) or postoperative pain are associated with decreased...

Are physician assistant and patient airway assessments reliable compared to anesthesiologist assessments in detecting difficult airways in general surgical patients?

Background Airway management remains one of the most important responsibilities of anesthesiologists. Prediction of difficult airway allows time for proper selection of equipment, technique, and personnel experienced in managing patients with difficult airway. Face to face preoperative anesthesia interviews are difficult to conduct as they necessitate patients traveling to the...

The effect of natural sounds on the anxiety of patients undergoing coronary artery bypass graft surgery

Background This study aims to investigate the effect of natural sounds on the anxiety of patients undergoing coronary artery bypass graft surgery (CABG). Methods In this clinical trial, 90 patients, who were candidates for CABG in an urban area of Iran, were selected and randomly assigned to intervention and control groups by the minimization method. In the intervention group...

Surgeons’ views on preoperative medical evaluation: a qualitative study

Background There is substantial variation in the practice of preoperative medical evaluation (PME) and limited evidence for its benefit, which raises concerns about overuse. Surgeons have a unique role in this multidisciplinary practice. The objective of this qualitative study was to explore surgeons’ practices and their beliefs about PME. Methods We conducted of semi-structured...

Fluid resuscitation practices in cardiac surgery patients in the USA: a survey of health care providers

Background Fluid resuscitation during cardiac surgery is common with significant variability in clinical practice. Our goal was to investigate current practice patterns of fluid volume expansion in patients undergoing cardiac surgeries in the USA. Methods We conducted a cross-sectional online survey of 124 cardiothoracic surgeons, cardiovascular anesthesiologists, and...

Pre- to postoperative coagulation profile of 307 patients undergoing oesophageal resection with epidural blockade over a 10-year period in a single hospital: implications for the risk of spinal haematoma

Background Epidural anaesthesia and analgesia are indicated for oesophageal surgery. A rare but serious complication is spinal haematoma, which can occur on insertion, manipulation or withdrawal of catheters. Evidence and guidelines are vague regarding which tests are appropriate and how to interpret their results. We aimed to describe how routine coagulation test results change...

Enhanced recovery protocols for colorectal surgery and postoperative renal function: a retrospective review

Background While enhanced recovery protocols (ERPs) reduce physiologic stress and improve outcomes in general, their effects on postoperative renal function have not been directly studied. Methods Patients undergoing major colorectal surgery under ERP (February 2010 to March 2013) were compared with a traditional care control group (October 2004 October 2007) at a single...

Preoperative fluid retention increases blood loss during major open abdominal surgery

BackgroundQuantification of renal fluid conservation is possible by urine analysis, and the results can indicate dehydration.

The prevalence of pulmonary complications after thoracic and abdominal surgery and associated risk factors in patients admitted at a government hospital in Harare, Zimbabwe-a retrospective study

Background The burden of HIV/AIDS in Sub-Saharan Africa has presented unusual and challenging acute surgical problems across all specialties. Thoraco-abdominal surgery cuts through muscle and thereby disrupts the normal anatomy and activity of the respiratory muscles leading to reduced lung volumes and putting the patients at greater risk of developing post-operative pulmonary...

Re-designing the pathway to surgery: better care and added value

The case for radical pathway re-design before surgery is in part driven by healthcare system pressures which are in turn the result of continuously rising demand in the face of tightly constrained resources. Such circumstances tend to drive revolutionary, rather than incremental, change. The current approach to preoperative assessment, that typically occurs in the weeks leading...
