Efeitos da manobra de hiperinsuflação manual seguida da compressão descompressão torácica manual em pacientes oncológicos

Abstract

Objective: to evaluate the effects of isolated manual hyperinflation (MH) maneuver and associated with manual chest compression and decompression (MCCD) on respiratory mechanics and vital signs of oncologic patients under invasive mechanical ventilation (IMV). Method: non-randomized clinical trial with 23 cancer patients admitted to the Erasto Gaertner Hospital, from January to June 2011 and August to December 2016, hemodynamically stable and under IMV. Data of tidal volume (TV), minute volume (MV), peak inspiratory pressure (Ppeak), heart rate (HR) and peripheral oxygen saturation (SpO2) were evaluated in three moments: before applying the maneuvers (AV1), immediately after the application of BS (AV2) and 10 min after application of MCCD (AV3). Results: the only variable that showed statistically significant change was SpO2 in the analysis between AV1 and AV2 (p = 0.010), in which medians were 99 (96-100) and 100 (97-100), respectively, an evolution attributed to MH maneuver isolated. Ppeak and HR values remained stable. Conclusion: the association between MH manuever and MCCD did not generate changes on respiratory mechanics and vital signs of oncologic patients under IMV. However, the MH maneuver isolated was effective in improving SpO2 in this population without causing significant hemodynamic changes. (English) [ABSTRACT FROM AUTHOR]
