Study summary

Endotracheal Intubation (EI) is performed in order to monitor the effectiveness of anesthesia and to control the patient's breathing during the surgery under general anesthesia. In EI, which is an invasive procedure, damage to the larynx and trachea may occur during the placement of the endotracheal tube or due to long-term use. Complications such as postintubation ulcer, laryngeal nerve paresis, arytenoid dislocation may develop in the early period due to EI, and patients may have complaints such as sore throat, swallowing problems, hoarseness, and cough in the postoperative period. This affects the comfort of the patients in the postoperative period. For this reason, it is important to prevent intubation-related symptoms of patients who will undergo surgical intervention before they occur.

Read the detailed description

Endotracheal Intubation (EI) is performed in order to monitor the effectiveness of anesthesia and to control the patient's breathing during the surgery under general anesthesia. In EI, which is an invasive procedure, damage to the larynx and trachea may occur during the placement of the endotracheal tube or due to long-term use. Complications such as postintubation ulcer, laryngeal nerve paresis, arytenoid dislocation may develop in the early period due to EI, and patients may have complaints such as sore throat, swallowing problems, hoarseness, and cough in the postoperative period. In addition, similar complaints may be encountered after extubation due to the displacement of the cuff of the EI and changes in the cuff pressure during the head and body positioning of the patient for surgical intervention after the EI. In the literature, studies examining the effect of intraoperative patient position on symptoms associated with postoperative intubation are limited. Baran Akkuş and Çaparlar (2020) evaluated the postoperative period of sore throat, hoarseness, dysphagia, and cough by controlling the cuff pressure in patients with hyperextension and supine position, and they did not find a significant difference between the groups. Although the severity of intubation-related complaints, which usually regress within 24 to 72 hours in the postoperative period, varies from patient to patient, it can affect the comfort of the patients in the early postoperative period.

In the literature, there are many studies conducted to relieve the symptoms of sore throat, cough, hoarseness, and dysphagia in patients after extubation. In these studies, pharmacological analgesic agents such as nonsteroidal anti-inflammatory drugs, steroids, opioids, local anesthetics; different anesthetic techniques, the use of different sized endotracheal tubes, intubation after complete muscle relaxation, minimizing cuff pressure, and lubricating gels such as local anesthetics or oral lozenges, sprays and mouthwash solutions are used around or inside the intubation tube cuff. There are many studies in the literature on the successful application of non-pharmacological agents in the treatment of pain. Patients with post-operative throat complaints are recommended to take warm liquids, avoid solid food, suck ice chips, use lozenges, and apply steam. The cold application creates vasoconstriction in the vessels in the area where it is applied, decreases the metabolic rate, and reduces edema. The cold application reduces muscle temperature by reducing the tension sensitivity of muscle spindles with the reflex effect of heat receptors or by inactivating trigger points in the muscles and helps to reduce muscle spasm. Thus, it reduces skin sensitivity by lowering the temperature of nerve fibers and receptors. Cold application is especially beneficial in post-traumatic pain, swelling, and muscle spasm. This affects the comfort of the patients in the postoperative period. For this reason, it is important to prevent intubation-related symptoms of patients who will undergo surgical intervention before they occur. Although it is seen in the literature that pharmacological, non-pharmacological, and herbal methods are applied to reduce postoperative sore throat, cough, hoarseness, and dysphagia, no study has been found examining the effect of the cold steam application on symptoms associated with IE.

Study arms

  • Experimental
    Prone position-Cold vapor group

    Cold vapor will be applied to the prone position experimental group patients for 15 minutes in the recovery room. For the study, Nebtime UN600A Ultrasonic Nebulizer Device will be used to apply cold steam to the patients which used in the hospital and calibrated (https://elmaslarmedikal.com.tr/urunler/nebtimeun600aultrasonik-nebulizator/). The parameters to be set on the device for the cold vapor to be applied to the patients in the early postoperative period will be vapor intensity level 5 (1-10), air blowing intensity 5 (1-10), heater intensity 1 (+10C), and timer 15 minutes. The patients will be evaluated by the researchers in terms of sore throat, cough, hoarseness, and dysphagia before and 15 minutes after the cold vapor application in the recovery room and at the 6th, 12th, and 24th hours after the cold vapor application in the postoperative service.

What researchers measure

Primary outcomes

  1. Cold vapor

    The sore throat, one of the intubation-related symptoms of the patients who underwent cold vapor, is decreased compared to those who do not. A score between 0 and 10 is taken from the Visual Analogue Scale (VAS). It is good that the score on the scales has decreased.

    Time frame: First 24 hours after surgery

  2. Cold vapor

    The cough, one of the intubation-related symptoms of the patients who underwent cold vapor, is decreased compared to those who do not. A score between 0 and 4 is taken from the Cough Severity Form (CSF). It is good that the score on the scales has decreased.

    Time frame: First 24 hours after surgery

  3. Cold vapor

    Swallowing, one of the intubation-related symptoms of the patients who underwent cold vapor, is decreased compared to those who do not. A score between 0 and 24 is taken from the Swallowing Impairment Score (SIS). It is good that the score on the scales has decreased.

    Time frame: First 24 hours after surgery

  4. Cold vapor

    The hoarseness, one of the intubation-related symptoms of the patients who underwent cold vapor, is decreased compared to those who do not. A score between 0 and 3 is taken from the Shout's Hoarseness Scale (SHS). It is good that the score on the scales has decreased.

    Time frame: First 24 hours after surgery

  5. Cold vapor

    The Perianesthesia Comfort Scale (PCS) of the patients for comfort who underwent cold vapor is decreased compared to those who do not. A score between 24 and 144 is taken from the PCS. It is good that the score from the PCS has increased.

    Time frame: 24th hour after surgery

Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.

Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
