The Pulmonary and Hemodynamic Effects of Two Different Recruitment Maneuvers After Cardiac Surgery

Abstract

The recruitment techniques with postmaneuver PEEP increased oxygenation and decreased atelectasis equally, whereas PEEP-20 provided more stable hemodynamic conditions than the CPAP maneuver.

Effects of different PEEP levels on respiratory mechanics and oxygenation after coronary artery bypass grafting

“…This effect was also found by Celebi et al [18] in another randomized controlled trial in which patients were ventilated with PEEP titrated to achieve the best PaO 2 .…”

Neonatal Pneumothorax Pressures Surpass Higher Threshold in Lung Recruitment Maneuvers: An In Vivo Interventional Study

“…27 Pulse showed the highest endurance to high pressures: the zero PEEP group presented bradycardia significantly earlier, at PIPs of 40 cm H 2 O, whereas the PEEP group showed bradycardia at PIP ϭ 70 cm H 2 O/PEEP ϭ 50 cm H 2 O. Bradicardia in the pediatric population is a well-known side effect of the sustained 40-cm H 2 O CPAP recruitment maneuver, whose use is now strongly discouraged. 23 One of the more significant findings of the study is that hemodynamic compromise occurred in the zero PEEP group at considerably lower PIPs than those that caused pneumothorax. This important but unexpected finding, that a larger ␦-pressure seems to induce more hemodynamic compromise with the same PIP, suggests that perhaps venous return is more compromised in this condition.…”

“…The estimation of the sample size was conducted taking similar studies as a reference. 22,23 All animals studied had been declared healthy after a veterinary examination.…”

Utilidad de las maniobras de reclutamiento (contra)

“…En los últimos años, diversos estudios clínicos y experimentales han mostrado la presencia de efectos cardiovasculares asociados a la MR [9][10][11][12][13][14] . El efecto hemodinámico principal encontrado es una disminución significativa del gasto cardíaco durante la realización de la maniobra.…”
