Initial Experience of Using First-Person Wearable Video Recording Technology During Central Venous Catheter Placement in the Cardiac Operating Room

OBJECTIVE

The aim of this study was to use wearable video-recording technology to measure precisely the timing of discrete events during perioperative central venous catheter (CVC) placements.

DESIGN

A single-center, observational, exploratory study on the use of wearable video-recording technology during intraoperative CVC placement.

SETTING

The study was conducted at a University Hospital.

PARTICIPANTS

Clinical anesthesia residents, cardiothoracic anesthesia fellows, and attending anesthesiologists participated in this study.

INTERVENTIONS

Participants were asked to use eye-tracking glasses prior to the placement of a CVC in the cardiac operating rooms. No other instruction was given to the participants.

MEASUREMENTS AND MAIN RESULTS

The authors measured the total time to complete the CVC placement, phase-specific time, and specific times of interest. They compared these times across 3 training levels and tested differences with analysis of variance. The authors' findings indicated significant differences in total CVC placement time when the procedure included a pulmonary artery catheter insertion (1,170 ± 364, 923 ± 272, and 596 ± 226 seconds; F2,63 = 12.71, p < 0.0001). Additionally, they found differences in interval times and times of interest. The authors observed a reduction of variability with increasing experience during the CVC placement phase.

CONCLUSIONS

In this observational study, the study authors describe their experience using first-person wearable video-recording technology to precisely measure the timing of discrete events during CVC placement by anesthesia residents and anesthesiologists. Future work will leverage the eye-tracking capabilities of the existing hardware to identify areas of inefficiency to develop actionable targets for interventions that could improve trainee performance and patient safety.

Assessment of buccal mucosa genotoxicity in insecticide-exposed urban fumigators in Cali, Colombia

OBJECTIVES

This study aimed to evaluate cytogenetic damage in the buccal mucosa of non-exposed subjects (N = 33) and insecticide-exposed fumigators (N = 31) in the urban area of Cali, Colombia.

MATERIAL AND METHODS

Through a questionnaire sociodemographic data, anthropometric measurements, state of health, and lifestyle were collected. Buccal micronucleus cytome (BMCyt) assay was using for evaluate cytogenetic damage.

RESULTS

The study showed that all fumigators used adequate personal protective equipment (PPE) and had low alcohol consumption. The authors did not find significant differences in BMCyt biomarkers between the groups (p > 0.05). Multivariate analysis showed a 13% increase in micronucleus (MN) frequency for every year of increasing age (OR = 1.13, p = 0.029), and higher MN with the decrease in daily fruit consumption (OR = 4.71, p = 0.084), without statistical significance.

CONCLUSIONS

The results between groups could be related to healthy habits and PPE use among the subjects. Int J Occup Med Environ Health. 2024;37(1):128-37.
