ENDOTRACHEAL Tube LIDOCAINE (ETT LIDOCAINE)

2. September 2026 aktualisiert von: Ohio State University

Application of a 5% Lidocaine Ointment to Endotracheal Tubes to Reduce Emergence Bucking: a Randomized Double-Blind Prospective Trial.

This prospective, randomized, double-blind, two-arm clinical trial will evaluate whether applying 5% lidocaine ointment to endotracheal tubes before intubation reduces airway irritation compared with standard water-based lubricant in adult patients undergoing general anesthesia. The primary objective is to determine whether lidocaine ointment decreases the incidence of coughing or bucking during emergence and extubation. Secondary objectives include evaluating the incidence and severity of postoperative sore throat and hoarseness, as well as intraoperative opioid requirements. Additional demographic and procedural data will be collected to characterize the study population and adjust for potential confounders. The study hypothesis is that 5% lidocaine ointment will reduce emergence coughing and improve postoperative airway comfort without increasing adverse outcomes.

Detaillierte Beschreibung

Emergence coughing or bucking is a common complication of general anesthesia with endotracheal intubation and may result in clinically significant increases in hemodynamic stress, airway irritation, postoperative discomfort, and potential complications. Although multiple pharmacologic strategies have been evaluated to reduce emergence coughing, the effectiveness of topical lidocaine preparations applied to the endotracheal tube remains uncertain.

This prospective, randomized, double-blind, two-arm clinical trial will evaluate whether applying 5% lidocaine ointment to the external surface of the endotracheal tube before intubation reduces coughing or bucking during emergence from general anesthesia compared with standard water-based endotracheal tube lubricant.

Adult patients undergoing elective surgical procedures requiring general anesthesia with oral endotracheal intubation will be randomized to receive either 5% lidocaine ointment or standard water-based lubricant applied to the external surface of the endotracheal tube immediately prior to intubation. The study will use standardized anesthetic management, double-blinding procedures, and consistent outcome assessment methods.

The primary outcome is the incidence of coughing or bucking during emergence from anesthesia, assessed from the time anesthetic agents are reduced for extubation until removal of the endotracheal tube. Secondary outcomes include the incidence and severity of postoperative sore throat and hoarseness at defined postoperative time points, as well as total intraoperative opioid administration converted to morphine milligram equivalents.

Additional demographic and procedural information, including age, sex, body mass index, American Society of Anesthesiologists physical status, airway assessment characteristics, duration of intubation, and surgical procedure type, will be collected to describe the study population and evaluate potential factors associated with outcomes.

The study aims to determine whether 5% lidocaine ointment provides a clinically useful strategy for reducing emergence-related airway irritation and improving postoperative airway comfort compared with standard endotracheal tube lubrication.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: 5% Lidocaine Ointment
Participants randomized to this arm will receive 5% lidocaine ointment applied to the external surface of the endotracheal tube immediately prior to endotracheal intubation. The ointment will be applied according to the study protocol before induction of general anesthesia.
A 5% lidocaine ointment will be applied as a thin, uniform layer to the external surface of the endotracheal tube immediately before endotracheal intubation. The ointment will be applied once according to the study protocol before induction of general anesthesia.
Aktiver Komparator: Water-Based Lubricant

Participants randomized to this arm will receive the institution's standard water-based lubricant applied to the external surface of the endotracheal tube immediately prior to endotracheal intubation. The lubricant will be applied according to routine clinical practice before induction of general anesthesia.

These entries are appropriate because both treatments are established clinical practices, with the investigational intervention being compared against an active standard-of-care comparator.

Institutional standard water-based endotracheal tube lubricant will be applied to the external surface of the endotracheal tube immediately before endotracheal intubation according to routine clinical practice before induction of general anesthesia.

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Incidence of Coughing or Bucking During Emergence from General Anesthesia
Zeitfenster: From initiation of emergence from anesthesia until endotracheal tube removal, assessed during the extubation period (approximately 5-30 minutes after anesthetic reduction).
The incidence of coughing or bucking occurring during emergence from anesthesia, defined as any cough or bucking movement from the time anesthetic agents are reduced for extubation until removal of the endotracheal tube. The outcome will be assessed by direct observation and recorded as the presence or absence of coughing/bucking and the number of bucking episodes using a standardized assessment.
From initiation of emergence from anesthesia until endotracheal tube removal, assessed during the extubation period (approximately 5-30 minutes after anesthetic reduction).
