Coagulation after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: a retrospective cohort analysis
AbstractPurposeCytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) benefit patients with peritoneal carcinomatosis. Nevertheless, this therapy is associated with considerable postoperative pain due to the extensive abdominal incision. While epidural analgesia offers efficacious pain control, CRS and HIPEC therapy is associated with perioperative coagulopathy that may impact its use. The purpose of this retrospective study is to characterize the postoperative coagulopathy in this patient subset and to develop a model that will help predict those at risk.MethodsOur database of patients treated w...

Agreement between venous and arterial blood gas analysis of acid-base status in critical care and ward patients: a retrospective cohort study
ConclusionsVenous gases are suitable for initial evaluation of acid-base status in critically ill patients. Based on clinical evaluation, an arterial sample may then be considered for confirmation, and thereafter, venous blood gases could be sufficient for monitoring response to treatment.

Massive hemorrhage and transfusion in the operating room
ConclusionsMassive hemorrhage is a multidisciplinary challenge that requires immediate response and communication between clinicians, nurses, other healthcare providers, laboratory testing, and blood banks. Basic knowledge and utilization of available products and therapies are inconsistent. A massive transfusion protocol can be used effectively to reduce chaos and ensure that correct treatments and proper dosing occur in a timely manner. (Source: Canadian Journal of Anesthesia)

Predictive factors of maternal hypothermia during Cesarean delivery: a prospective cohort study
AbstractPurposeAlthough perioperative hypothermia may increase maternal morbidity, active warming is infrequently performed to maintain normothermia during Cesarean delivery (CD). The aim of this prospective observational study was to determine the factors associated with maternal hypothermia in this setting.MethodsWomen scheduled for elective or emergency CD were consecutively included in this study from November 2014 to October 2015. Maternal temperature was measured using an infrared tympanic thermometer on the patient ’s arrival in the operating room, at skin incision, and at the end of skin suture. Maternal hypo...

Low-dose subcutaneous ketamine for postoperative pain management in Rwanda: a dose-finding study
ConclusionAdding subcutaneous ketamine to standard analgesic measures resulted in decreases in postoperative pain scores without serious side effects. These data can be used to inform a randomized controlled trial to compare subcutaneous ketamine plus standard care with placebo plus standard care for reducing postoperative pain.

Contribution of the nasal passage to face mask ventilation: a prospective blinded randomized crossover trial
AbstractBackgroundPrevious studies have shown that the nasal passage plays an important role in manual face mask ventilation, but this has yet to be quantitatively assessed. We conducted a prospective randomized crossover clinical trial to compare the change in pressure-controlled face mask tidal volume with and without nasal airway occlusion.MethodFemale patients undergoing elective surgery under general anesthesia served as study subjects. Patients were randomly assigned to face mask ventilation beginning either with or without nasal passage occlusion (achieved with a swimmer ’s nose clip), followed by removal or a...

Serotonergic medications, herbal supplements, and perioperative serotonin syndrome
ConclusionEven small doses of fentanyl administered to patients taking multiple serotonergic medications and herbal supplements may trigger serotonin syndrome. Prompt reversal of serotonin toxicity in one patient by naloxone illustrates the likely opioid-mediated pathogenesis of serotonin syndrome in this case. It also highlights that taking serotonergic agents concomitantly can produce the compounding effect that causes serotonin syndrome. The delayed presentation of serotonin syndrome in the patient who received a large dose of midazolam suggests that outpatients taking multiple serotonergic drugs who receive benzodiazep...

ConclusionWhile it is unlikely that most medical practitioners will ever encounter nerve agent poisoning, it is critical to be aware of the presenting symptoms and how best to treat patients exposed to these deadly agents. History has shown that rapid medical treatment can easily mean the difference between life and death for a patient in this situation. (Source: Canadian Journal of Anesthesia)

The association between the time from oxytocin cessation during labour to Cesarean delivery and postpartum blood loss: a retrospective cohort study
We examined the association between oxytocin recovery interval, i.e., the time from discontinuing oxytocin to Cesarean delivery (CD) for labour arrest, and blood loss.MethodsThis retrospective cohort study included women who underwent CD for labour arrest following oxytocin-augmented labour from July 1, 2013 to July 19, 2015 at our institution. Data were collected on patient demographics, labour and delivery characteristics, oxytocin induction and augmentation, recovery interval, and PPH risk factors. The primary outcome was estimated blood loss (EBL), calculated using the hematocrit variation method.ResultsData on 490 wom...

Evaluation of the analgesia nociception index (ANI) in healthy awake volunteers
AbstractBackgroundAnalgesia might be evaluated with simple changes in vital signs, a non-specific and non-sensitive method. Heart rate variability (HRV) correlates with autonomous nervous system activity and can be used to evaluate painful stimuli. Heart rate variability is then transformed into a numeric scale called the analgesia nociception index (ANI), where higher values represent predominant parasympathetic tone, thus low nociception. Under general anesthesia, the ANI decreases following painful stimuli and increases after administration of analgesia, but significant interindividual variability is present. The goal o...

A retrospective assessment of prognostication in 456,685 patients undergoing elective major non-cardiac surgery
AbstractBackgroundThe accuracy of patient prognostication varies extensively in studies of select populations. Prognostication is an important component of patient selection for elective surgery. This retrospective study assessed patient prognostication prior to elective surgery by comparing the observed with the expected number of deaths in such patients.Study designWe used population-based administrative data to identify all adults undergoing one of 13 most common elective major non-cardiac gender-neutral surgeries in Ontario, Canada from 2002 –2014. Survival status within one year of surgery was determined by link...
