Implementation of continuous temperature monitoring during perioperative care: a feasibility study.

BACKGROUND: Continuous body temperature monitoring during perioperative care is enabled by using a non-invasive "zero-heat-flux" (ZHF) device. However, rigorous evaluation of whether continuous monitoring capability improves process of care and patient outcomes is lacking. This study assessed the feasibility of a large-scale trial on the impact of continuous ZHF monitoring on perioperative temperature management practices and hypothermia prevention. METHODS: A feasibility study was conducted at a tertiary hospital. Participants included patients undergoing elective surgery under neuraxial or general anesthesia, and perioperative nurses and anesthetists caring for patient participants. Eighty-two patients pre and post introduction of the ZHF device were enrolled. Feasibility outcomes included recruitment and retention, protocol adherence, missing data or device failure, and staff evaluation of intervention feasibility and acceptability. Process of care outcomes included temperature monitoring practices, warming interventions and perioperative hypothermia. RESULTS: There were no adverse events related to the device and feasibility of recruitment was high (60%). Treatment adherence varied across the perioperative pathway (43 to 93%) and missing data due to electronic transfer issues were identified. Provision of ZHF monitoring had most impact on monitoring practices in the Post Anesthetic Care Unit; the impact on intraoperative monitoring practices was minimal. CONCLUSIONS: Enhancements to the design of the ZHF device, particularly for improved data retention and transfer, would be beneficial prior to a large-scale evaluation of whether continuous temperature monitoring will improve patient outcomes. Implementation research designs are needed for future work to improve the complex area of temperature monitoring during surgery.  TRIAL REGISTRATION: Prospective registration prior to patient enrolment was obtained from the Australian and New Zealand Clinical Trials Registry (ANZCTR) on 16th April 2021 (Registration number: ACTRN12621000438853).

Patient Positioning Guidelines for Gastrointestinal Endoscopic Procedures.

Patient positioning during gastrointestinal endoscopic procedures has received minimal attention compared with surgical procedures performed in the surgical setting. However, prolonged endoscopic interventions on patients and the increasing requirement for general anesthesia have changed to need for patient positioning guidelines. The objective of this study was to test whether patient positioning guidelines for surgical procedures in surgical suites are suitable for gastrointestinal endoscopic procedures without negatively impacting safety and procedure duration. This was an observational feasibility study with volunteers of different body mass index categories. Volunteers were positioned in supine, lateral, and prone positions on an operating table and thereafter on an endoscopy stretcher and asked for comfort levels. Except for arm and head positioning in lateral and prone positions, it was possible to replicate the patient positioning guidelines. Alternative options were explored for the positioning of arms and head to optimize oral access. Besides minor adjustments, we were able to replicate the positioning guidelines and adhere to pressure and nerve injury prevention guidelines. Concept endoscopic patient positioning guidelines were developed. It is recommended to review the "swimmer's" position. Endoscopic patient positioning guidelines should become part of the National Practice Standards and education curriculum of endoscopy nurses.
