Abstract

OBJECTIVES:

To determine the characteristics of laser-protected endotracheal tubes (LPETs) valued by otolaryngologists performing transoral laser surgery in the head and neck and to measure LPET stiffness.

METHODS:

An online questionnaire was completed by American Broncho-Esophagological Association (ABEA) and American Head and Neck Society (AHNS) members. LPET distal end compliance was measured in a biomechanics laboratory.

RESULTS:

A total of 228 out of 2109 combined ABEA and AHNS members completed the survey. The following LPET characteristics, which were properties of the Medtronic Laser-Shield II tube (MLST), were highly valued: softness and flexibility, surface smoothness, and a tight-to-shaft balloon (all P < .01). Prior to industry-driven discontinuation of the MLST, 52% of surgeons (78% of fellowship-trained laryngologists [FTLs]) reported using it; afterward, 58% reported using the stainless steel, Mallinckrodt Laser-Flex tube (MLFT). Forty-six percent of all respondents (69% of FTLs) did not consider cost being a factor in LPET choice. Biomechanical testing revealed the distal end of the MLST to be 3.45 times more compliant than the MLFT ( P < .01).

CONCLUSION:

Members of the ABEA and AHNS, particularly FTLs, highly value distinguishing properties of the now discontinued MLST. Manufacturers should consider this in the design of new LPETs.
