Postintubation Sequels: Influence of Fluticasone and Technique of Intra-Operative Muscle Relaxation.

BACKGROUND

Postintubation sequels (PIS) are a cause of serious concern in the postoperative period.

AIM: The aim of this study is to find the influence of preoperative inhaled steroid and technique of muscle relaxation on PIS.

SETTINGS AND

DESIGN

This prospective, exploratory pilot study was conducted on 120 adult American Society of Anesthesiologist physical status Class I and II patients undergoing general anesthesia (GA) with muscle relaxation and cuffed endotracheal tube (ETT) insertion.

PATIENTS AND

METHODS

Patients were randomized into four groups as follows: intermittent muscle relaxation with preanesthetic inhalation of either distilled water puffs (Group ID) or fluticasone puffs (Group IF); continuous infusion of muscle relaxant with preanesthetic inhalation of either distilled water puffs (Group CD) or fluticasone puffs (Group CF). After induction of GA, ETT was inserted. The intra-cuff pressure was maintained constant. The trachea was extubated in the light plane in intermittent groups and in the deep plane in continuous groups.

STATISTICAL ANALYSIS: Qualitative parameters were compared using the Chi-square test and quantitative parameters using repeated measure ANOVA followed by Tukey's test.

RESULTS

Group CF had significantly less incidence of sore throat and hoarseness compared to groups ID and IF. The severity of sore throat was more in groups ID and IF than in groups CF and CD (P < 0.002). The severity of hoarseness was least in group CF (23.3%) and highest in group IF (90%). None of the patients had a cough in group CF. The incidence and severity of dysphagia were significantly less in group CF as compared to other groups (P < 0.005 and P < 0.008, respectively).

CONCLUSION

Continuous infusion of muscle relaxant with extubation in deep plane of anesthesia with preanesthetic inhalation of fluticasone puffs results in lesser incidence and severity of PIS.
