Hip dysplasia hiding in plain sight: A retrospective analysis of radiology reports.

Introduction: Timely recognition of dysplastic hip morphology is critical to facilitate appropriate management before significant joint damage has developed. It is likely that radiologist under reporting contributes to delays in diagnosis. This study aimed to assess how often adult hip dysplasia goes undetected in radiological reports and to identify clinical and radiological variables that impact the likelihood of detection of dysplasia by radiologists.

Tranexamic Acid Use During Surgery Associated with Extension of Acute Perioperative Type 1 Myocardial Infarction: A Case Report.

Case Presentation: A 70-year-old women presented to a regional hospital after a fall, resulting in a periprosthetic femoral fracture. Preoperative echocardiogram was ordered to investigate a cardiac murmur, and unexpectedly, a significant regional wall abnormality was found. Further repeat electrocardiograph and troponin blood biomarker analysis demonstrated the patient had suffered an acute type 1 myocardial infarction after admission to the ward, without exhibiting classical ischemic cardiac symptoms.

The effect of perioperative sustained-release opioid use on long-term opioid dispensing following total knee arthroplasty: a retrospective cohort study.

Aims: To determine the impact of perioperative sustained-release (SR) opioid use on total inpatient opioid consumption and longer-term outpatient dispensing for three months following elective total knee arthroplasty (TKA).

Methods: Patients who underwent primary unilateral TKA between 1 January and 31 December 2018 at Counties Manukau Health were retrospectively identified. Participants were stratified into two groups by inpatient use or avoidance of strong SR opioids (OxyContin or M-Eslon).

Incidence and predictors of iron deficiency anaemia in parturients undergoing elective caesarean section at a tertiary hospital in New Zealand: a retrospective, observational cohort study.

Background: Worldwide, iron deficiency anaemia in pregnancy is a significant problem which can be especially problematic when delivery is by caesarean section, a procedure associated with significant blood loss. Optimising iron stores pre-delivery remains an overarching goal. We aim to measure the incidence of iron deficiency anaemia in patients undergoing elective caesarean section at our institution and determine any associated predictors, as well as adverse outcomes.

Intravenous Local Anesthetic Compared With Intraperitoneal Local Anesthetic in Laparoscopic Colectomy: A Double-blind Randomized Controlled Trial.

Introduction: Controlling perioperative pain is essential to improving patient experience and satisfaction following surgery. Traditionally opioids have been frequently utilized for postoperative analgesia. Although they are effective at controlling pain, they are associated with adverse effects, including postoperative nausea, vomiting, ileus, and long-term opioid dependency.

Perioperative Pain and Addiction Interdisciplinary Network (PAIN): consensus recommendations for perioperative management of cannabis and cannabinoid-based medicine users by a modified Delphi process.

In many countries, liberalisation of the legislation regulating the use of cannabis has outpaced rigorous scientific studies, and a growing number of patients presenting for surgery consume cannabis regularly. Research to date suggests that cannabis can impact perioperative outcomes. We present recommendations obtained using a modified Delphi method for the perioperative care of cannabis-using patients.

Predictors of hyponatremia following elective primary unilateral knee arthroplasty at a tertiary centre: A retrospective observational cohort and predictive model.

Introduction: Hyponatremia is a common electrolyte disorder. This can be associated with nausea, disorientation and in more serious cases a decreased level of consciousness or neurological deficits. These symptoms may lead to increases in the cost of hospital care and significant morbidity.

Multidisciplinary survey of current and future use of emergency laparotomy risk assessment scores in New Zealand.

Risk prediction is an important part of the management of emergency laparotomy (EL) patients. This study aims to investigate the current use of and future directions for EL risk prediction scores. New Zealand members of the Royal Australasian College of Surgery (RACS), Australian and New Zealand College of Anaesthetists (ANZCA) and College of Intensive Care Medicine (CICM) were invited to participate in an anonymous online survey.

The prognostic implication of perioperative cardiac enzyme elevation in patients with fractured neck of femur: A systematic review and meta-analysis.

Background: Neck of Femur (NOF) fractures are a common injury in comorbid elderly patients which are associated with increased rates of morbidity and mortality following fracture. Because of their injury, patients can experience reductions in quality of life and independent living leading to transfer to nursing home or dependent levels of care. Numerous factors are associated with either complications or reductions in survival following fractured NOF.

Intraoperative cell salvage use reduces the rate of perioperative allogenic blood transfusion in patients undergoing periacetabular osteotomy.

Blood loss during periacetabular osteotomy (PAO) is variable, with losses ranging from 100 to 3900 ml in published series. Perioperative allogenic blood transfusion is frequently utilized although is associated with significant risk of morbidity. Cell salvage (CS) is a common blood conservation tool; however, evidence supporting its use with PAO is lacking.

The interaction between pre-operative anaemia and peri-operative blood transfusion on patient outcomes following general surgical procedure: a retrospective review.

Aim: To assess the incidence of pre-operative anaemia in patients presenting for general surgery and determine the relationship between pre-operative anaemia, transfusion and post-operative metrics including length of stay (LOS) and infectious complications.

Method: A retrospective cohort of 1,186 patients. Stratification into two groups with and without pre-operative anaemia through propensity score matching.

Restrictive Versus Liberal Fluid Regimens in Patients Undergoing Pancreaticoduodenectomy: a Systematic Review and Meta-Analysis.

Background: Pancreaticoduodenectomy is associated with significant morbidity and mortality which may be influenced by perioperative fluid management. It remains unclear whether liberal and restrictive fluid regimens impact mortality and morbidity in patients undergoing pancreaticoduodenectomy.

Methods: Medline, EMBASE, Cochrane Library and clinicaltrials.

Plasma Ropivacaine Concentrations Following Local Infiltration Analgesia in Total Knee Arthroplasty: A Pharmacokinetic Study to Determine Safety Following Fixed-Dose Administration.

Background And Objectives: The primary aim of this study was to examine the pharmacokinetics of ropivacaine in patients undergoing elective total knee arthroplasty with local infiltration analgesia as the primary analgesic method. We also sought to determine the incidence of biochemical toxicity through measurement of plasma ropivacaine concentrations over the first 24 hours postoperatively.

Methods: This was a prospective, observational study of 15 patients undergoing elective total knee arthroplasty.

Reliability of a point-of-care device for international normalized ratio testing during the three surgical phases of orthotopic liver transplantation: a retrospective observational study.

Purpose: To investigate the reliability of a point-of-care device, the HEMOCHRON(®) Jr. Signature, for measuring the international normalized ratio (INR) during the three surgical phases of liver transplantation.

Methods: A retrospective review was performed on patients undergoing liver transplantation during July to December 2013.

Disseminated haemangioblastoma without evidence of the von Hippel-Lindau syndrome or haemangioblastomatosis--A case report and clinico-pathological correlation.

A 71-year-old Caucasian female presented to our service with disseminated cranial and spinal haemangioblastomata but no other features to suggest the von Hippel-Lindau syndrome. We feel that this represents cellular dissemination through the cerebro-spinal fluid and may be an intermediate step to the development of frank haemangioblastomatosis. By comparing this presentation to that of other tumours we have suggested a potential pathological mechanism and have discussed its management.
