Effects of recruitment maneuver on atelectasis in anesthetized children.
BACKGROUND General anesthesia is known to promote atelectasis formation. High inspiratory pressures are required to reexpand healthy but collapsed alveoli. However, in the absence of positive end-expiratory pressure (PEEP), reexpanded alveoli collapse again. Using magnetic resonance imaging, the impact of an alveolar recruitment strategy on the amount and distribution of atelectasis was tested....
متن کاملEffect of Lung Recruitment Maneuver in Children with Acute Lung Injury
Background Acute lung injury (ALI) is defined as PaO2/FiO2 less than 300 with bilateral pulmonary infiltrates, without pressure is the top of the left atrium. Early diagnosis and treatment of pediatric ALI and find new cases is very important. Accurate diagnosis and effective steps to treating these patients is essential in the outcome of ALI. This study was conducted to show the impact of recr...
متن کاملCritical closing pressure explains cerebral hemodynamics during the Valsalva maneuver.
The Valsalva maneuver (VM), a voluntary increase in intrathoracic pressure of approximately 40 mmHg, has been used to examine cerebral autoregulation (CA). During phase IV of the VM there are pronounced changes in mean arterial blood pressure (MABP), pulse interval, and cerebral blood flow (CBF), but the changes in CBF are of a much greater magnitude than those seen in MABP, a finding to date a...
متن کاملCerebral hemodynamics during the Valsalva maneuver: insights from ganglionic blockade.
BACKGROUND AND PURPOSE The aim of this study was to differentiate the mechanical effects of the Valsalva maneuver (VM) from the effects of changes in autonomic neural activity on cerebral hemodynamics in humans. METHODS Nine healthy subjects performed the VM before and after autonomic ganglionic blockade with trimethaphan. Blood pressure (BP) was measured in the radial artery with an indwelli...
متن کاملAnalysis of the effects of the alveolar recruitment maneuver on blood oxygenation during bariatric surgery.
UNLABELLED BACKGROUND AND METHDS: Alveolar recruitment maneuver (ARM) is indicated in the treatment of intraoperative atelectasis. The objective of the present study was to compare two techniques of ARM using the response of the PaO2/FiO2 ratio and [PaO2 + PaCO2] in patients with grade III obesity. METHODS This was an open prospective study with adult patients with grade III obesity who under...
