Evaluation of the influence of pulmonary hypertension in ultra-fast-track anesthesia technique in adult patients undergoing cardiac surgery

Objective

To evaluate the influence of pulmonary hypertension in the ultra-fast-trackanesthesia technique in adult cardiac surgery.

Methods

A retrospective study. They were included 40 patients divided into twogroups: GI (without pulmonary hypertension) and GII (with pulmonaryhypertension). Based on data obtained by transthoracic echocardiography. Weconsidered as the absence of pulmonary hypertension: a pulmonary arterysystolic pressure (sPAP) <36 mmHg, with tricuspid regurgitation velocity<2.8 m/s and no additional echocardiographic signs of PH, and PH aspresence: a sPAP >40 mmHg associated with additional echocardiographicsigns of PH. It was established as influence of pulmonary hypertension: theimpossibility of extubation in the operating room, the increase in the timeinterval for extubation and reintubation the first 24 hours postoperatively.Univariate and multivariate analyzes were performed when necessary.Considered significant a P value <0.05.

Results

The GI was composed of 21 patients and GII for 19. All patients (100%) wereextubated in the operating room in a medium time interval of 17.58±8.06 minwith a median of 18 min in GII and 17 min in GI. PH did not increase thetime interval for extubation (P=0.397). It requiredreintubation of 2 patients in GII (5% of the total), without statisticallysignificant as compared to GI (P=0.488).

Conclusion

In this study, pulmonary hypertension did not influence on ultra-fast-trackanesthesia in adult cardiac surgery.
