Clearing the Smoke: The Evidence behind Risk of Electrocautery Smoke and Mitigation Strategies.

Background: Electrocautery has been a useful, fundamental instrument utilized for surgical procedures since its implementation in the 1920s. However, concerns exist regarding the health hazards of the by-product smoke associated with the use of electrocautery. Methods: A comprehensive review of articles on the composition, mitigation, and effects of smoke was conducted using the PubMed search engine and excluding articles that did not meet the predetermined inclusion criteria. From January 1963 to December 2021, a total of 264 articles resulted, and a total of 69 articles were included in this narrative review. Results: Surgical smoke contains volatile organic compounds, polycyclic aromatic compounds, viral particles, and ultrafine particles. There has been some evidence of mutagenicity to bacterial cells during animal in vivo studies, and one human survey study has shown similar mutagenic effects. We also discuss additional hemostatic techniques that can be used, including the use of hemostatic and antithrombolytic agents, epinephrine infiltration, and the use of tourniquet when appropriate. Conclusions: Further studies should be conducted regarding human effects, but until the data are available, we recommend precautionary measures and actions to protect operating room staff from cautery smoke exposure.

Is There a Difference in Abdominal Wall Muscle Strength, Endurance, and Motor Control Following Bilateral DIEP and TRAM Flaps for Breast Reconstruction?

Background: Abdominal donor site complications in bilateral pedicled transverse rectus abdominis muscle (TRAM) have been a concern when compared with bilateral deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study aimed to assess the strength, endurance, and motor control in patients undergoing DIEP and TRAM flaps. Methods: A prospective, cohort study was performed at a single institution including patients who underwent pedicled TRAM and DIEP flap reconstruction after mastectomy from August 2017 to August 2018. Patients underwent pre- and postoperative testing involving rectus abdominis, prone plank, side bridge, and trunk flexor tests. Descriptive analyses and multivariate linear regressions were performed. Results: The final analysis included a total of 9 patients, 4 of whom underwent TRAM flap reconstruction while 5 underwent DIEP flap reconstruction. The tests were not statistically significant between the TRAM versus DIEP groups, including rectus abdominis mean time decrease (0.25 vs 0.60 sec, P = .51), prone plank time increase (1.38 vs 1.38 sec, P = .51), right side bridge time increase (7.54 sec vs 32.15 sec, P = 1.00), left side bridge time increase (2.14 vs 44.5 sec, P = .37), and trunk flexor time decrease (4.68 vs 1.68 sec, P = .44). Overall complications were similar between the 2 groups. Conclusions: No significant difference in abdominal donor site morbidity was found when comparing the 2 groups. This article provides a point of conversation with patients when discussing available reconstruction options.
