End-tidal carbon dioxide in the early phase of cardiopulmonary exercise testing prior to major colorectal cancer surgery associates with postoperative outcome.
Cardiopulmonary exercise testing (CPET) objectively informs preoperative risk stratification prior to major surgery. CPET facilities are resource intensive and therefore more cost-effective triage methods are desirable for scalability. We tested two dynamic CPET parameters (end-tidal CO
2 (Pet CO2 ) and heart rate (HR)) to early phase exercise and resting diffusion capacity (DLCO) as potential point of care assessments that could be used outside of formal CPET testing facilities. ⋯ Assessment of DLCO at rest and dynamic assessment of Pet CO2 during the early phase of exercise may potentially be developed as inexpensive point-of-care triage tools to scale objective preoperative risk assessment. -

Near-infrared spectroscopy and processed electroencephalogram monitoring for predicting peri-operative stroke risk in cardiothoracic surgery: An observational cohort study.
Stroke is a feared complication after cardiothoracic surgery, with an incidence of around 2 to 3%. Anaesthesia and postoperative sedation may obscure clinical symptoms of stroke and thus delay diagnosis and timely intervention. ⋯ Cumulative intra-operative BIS values below 25 and longer duration of MAP below 60 mmHg were associated with the occurrence of peri-operative stroke within 3 days after cardiothoracic surgery. Prospective studies are warranted to evaluate a causal relationship between low BIS and stroke to establish whether avoiding intra-operative BIS values below 25 might reduce the incidence of peri-operative stroke.

Fentanyl exhibits interindividual variability in its dose requirement due to various nongenetic and genetic factors such as single nucleotide polymorphisms (SNPs). This study aims to develop and cross-validate robust predictive models for postoperative fentanyl analgesic requirement and other related outcomes in patients undergoing major breast surgery. Data regarding genotypes of 10 candidate SNPs, cold pain test (CPT) scores, pupillary response to fentanyl (PRF), and other common clinical characteristics were recorded from 257 patients undergoing major breast surgery. ⋯ The variant genotype of CTSG (rs2070697), higher intraoperative fentanyl use, and higher CPT scores were associated with significantly lower TFA. The predictive models for 24-hour postoperative fentanyl requirement, pain scores, and TFA had R-squared values of 0.313 (SVM-Linear), 0.434 (SVM-Linear), and 0.532 (RF), respectively. We have developed and cross-validated predictive models for 24-hour postoperative fentanyl requirement, 24-hour postoperative pain scores, and TFA with satisfactory performance characteristics and incorporated them in a novel web application.

Randomized Controlled TrialEffect of Different Administration Routes of Dexmedetomidine on Postoperative Delirium in Elderly Patients Undergoing Elective Spinal Surgery: A Prospective Randomized Double-Blinded Controlled Trial.
Intravenous dexmedetomidine has been reported to decrease the occurrence of postoperative delirium (POD) in elderly patients. Nevertheless, some previous studies have indicated that intratracheal dexmedetomidine and intranasal dexmedetomidine are also effective and convenient. The current study aimed to compare the effect of different administration routes of dexmedetomidine on POD in elderly patients. ⋯ For patients aged ≥60 years undergoing spinal surgery, compared with the intranasal route of dexmedetomidine, intravenous and intratracheal dexmedetomidine reduced the incidence of early POD. Meanwhile, intravenous dexmedetomidine was associated with better sleep quality after surgery, and intratracheal dexmedetomidine resulted in a lower incidence of POST. Adverse events were mild in all 3 administration routes of dexmedetomidine.

ReviewAnxiety in Children: A review on how to address it in the perioperative setting post pandemic.
In this paper, we review the psychological burden of SARS-CoV-2 on children and how health care workers can play a role in mitigating its mental health impact during anesthetic procedures. We evaluate the societal changes that have affected children over 2 years of the pandemic and the subsequent soaring rates of anxiety and depression reported. ⋯ Providers can utilize techniques based on developmental milestones, Certified Child Life Specialists, parental presence during induction, and medications to reduce anxiety. As health care workers, we need to recognize and address these concerns as untreated mental health issues can leave long-term consequences for children.
