| Summary: | Endotracheal intubation is one of airway management which often be done in
general anesthesia. One of the side effects of endotracheal intubation is sore throat
due to trauma of the pharyngeal mucous caused by laryngoscopy and endotracheal
cuff-pressure. There are some ways to reduce sore throat, such as control of intracuff
pressure.This study was carried out to compare incidence of postextubationsore
throat by measuring the cuff-pressure using manometer to that of
palpation.
This study was a double-blind randomized controlled trial. The population of this
study were patients who undergo elective surgery with general anesthesia at
GBST RSUP Dr. SardjitoYogyakarta which consist of male and female, 18-60
years of age, and physical status of ASA according to class I and II.
This study involves 150 patients which were then divided into 2 groups,
consisting 75 patients. Group A was defined as the group in which the cuff
pressure of 20 cmH2O wasmeasured by manometer, and group B was defined as
the group in which the cuff pressure of 20 cmH2O was estimated by palpation.
Cuff pressure measurement in both groups were done before extubation. During
the study period, 2 subjects were dropped from this study, so the total subject in
the end of study period were 148 patients.
There were no statistically significant difference of sore throat, in the events after
patients gain full consciousness, and 2 hours post-operative procedures in both
groups (p > 0,05),whereas 6 hours and 24 hours post operative procedures in both
group were statistically significant difference (P<0,05)
There were 10 subjects with sore throat, after gaining full consciousness in group
A (13,3%), and 18 subjects in group B (24,7%). There were 8 subjects with sore
throat at 2 hours post-operation in group A (10,7%), and 16 subjects in group B
(21,9%). The incidence of sore throat at 6 hours post-operation were 4 subjects in
group A (5,3%), and 13 subjects in group B (17,8%). Lastly, for the sore throat
reported at 24 hours post-operative procedures, there were 2 subjects in group A
(2,7%), and 10 patients in group B (13,7%).
The incidence of post-operative sore throat in the group in which the endotracheal
tube intra cuff-pressure were measured by manometer lower than by palpation
estimation
