| Reinius et al.
[2] |
Analyze the effect of general anesthesia and three different ventilatory strategies |
Prospective and randomized |
Thirty morbidly obese patients (body mass index 45 ± 4 kg/m−2) |
A recruitment maneuver followed by PEEP reduced atelectasis, whereas, PEEP or a recruitment maneuver alone did not. |
| Chalhoub et al. [6] |
Evaluate the effect of a vital capacity maneuver (VCM), followed by ventilation with positive end-expiratory pressure (PEEP), on arterial |
Prospective and randomized |
Fifty-two morbidly obese patients (body mass index >40 kg/m−2) |
The addition of VCM to PEEP improves intraoperative arterial oxygenation in morbidly obese patients undergoing open bariatric surgery |
| Talab et al. [7] |
Evaluate the safety and efficacy of the VCM followed by different levels of PEEP |
Prospective and randomized |
Sixty-six obese patients (body mass index 30 - 50 kg/m−2) |
Intraoperative alveolar recruitment with a VCM followed by 10 cm H2O prevents lung atelectasis and improves oxygenation, PACU stay, and pulmonary complications |
| Whalen et al. [8] |
Quantitate the effects of recruitment maneuvers followed by PEEP on PaO2 |
Prospective and randomized |
Twenty patients (body mass index >40 kg/m−2) |
Recruitment maneuvers followed by PEEP effectively increases intraoperative PaO2 |
| Futier et al. [9] |
Effect of PEEP and recruitment maneuver on end-expiratory lung volume (EELV), oxygenation and respiratory mechanics |
Prospective and non-randomized |
Sixty patients |
Recruitment maneuver combined with PEEP improved EELV, respiratory mechanics, and oxygenation; whereas, PEEP alone did not |
