Abstract

BACKGROUND
Fentanyl-induced cough (FIC) is a transient condition with a reported incidence of 18% to 65% depending on the dose and route of administration of fentanyl. Nonpharmacological methods to prevent FIC are more cost-effective than medications. Dilution of fentanyl has a proven role in the prevention of FIC. Acupressure can also prevent FIC because it has a proven role in the treatment of cough.
METHODS
This study included 225 female patients with an American Society of Anesthesiologists physical status of I or II who were randomly divided into 3 groups of 75 patients each. Patients in the control group received undiluted fentanyl at 3 µg/kg, patients in the acupressure group received undiluted fentanyl at 3 µg/kg with acupressure, and patients in the dilution group received diluted fentanyl at 3 µg/kg. Coughing was noted within 2 min of fentanyl administration. The severity of FIC was graded as mild (1-2 coughs), moderate (3-4 coughs), or severe (≥5 coughs). The timing of coughs was also noted.
RESULTS
The incidence of FIC was 12.7% in the control group, 6.8% in the dilution group, and 1.3% in the acupressure group. The difference in the incidence of cough was statistically significant (P = 0.008) between the control and acupressure groups. The difference in the severity of cough among the groups was not statistically significant. The median onset time of cough among all groups was 9 to 12 seconds.
CONCLUSIONS
The application of acupressure prior to administration of fentanyl significantly reduces the incidence of FIC. Dilution of fentanyl also reduces the incidence of FIC, but the difference is not statistically significant.
