Pressure-controlled ventilation could decrease intraoperative blood loss and improve airway pressure measures during lumbar discectomy in the prone position: A comparison with volume-controlled ventilation mode

Volume-controlled ventilation versus pressure-controlled ventilation during spine surgery in the prone position: A meta-analysis

“…A total of 2587 relevant studies were enrolled according to the searching strategy, and 8 RCTs [ 6 , 11 , [13] , [14] , [15] , [16] , [17] , [18] ] were ultimately selected for meta-analysis. Fig.…”

Kreislaufstillstand unter besonderen Umständen

“…Eine kontrollierte Beatmung bei Patienten mit Kreislaufstörungen ist jedoch mit erheblichen Risiken verbunden, die mit der Nebenwirkung von Anästhetika und dem Anstieg des intrathorakalen Drucks [ 56 ] verbunden sind und zu folgenden Ergebnissen führen können [ 57 ]: weitere Abnahme des verbleibenden Herzzeitvolumens durch Beeinträchtigung des venösen Rückstroms zum Herzen, insbesondere bei stark hypovolämen Patienten Reduzierte diastolische Füllung bei Herzbeuteltamponade Umwandlung eines Pneumothorax in einen Spannungspneumothorax Zunahme des Blutverlusts aus venösen Blutungsstellen …”

Effect of target-controlled pressure-controlled ventilation on percutaneous nephrolithotripsy patients under general anesthesia: a retrospective study

“…PPCs mainly include respiratory tract infection, respiratory failure, pleural effusion, atelectasis, pulmonary edema, pneumothorax, and acute lung injury, among which ventilator-related lung injury is one of the leading causes of PPCs. Volume-controlled ventilation (VCV) and pressurecontrolled ventilation (PCV) are commonly used ventilation modes in patients undergoing general anesthesia (5)(6)(7). VCV can ensure tidal volume, but the airway pressure changes considerably, thus increasing the potential for barotrauma.…”

“…PCV can meet tidal volume requirements while maintaining low airway pressure. Studies have shown that PCV is effective in protecting the lungs, possibly because PCV produces an exponentially decreasing flow waveform so that the inhaled gas is evenly diffused and distributed in the lung tissue, promoting the expansion of the distal alveoli while avoiding local overexpansion (7,8). During PCV, the preset pressure level is reached by a higher initial inspiratory flow rate at the beginning of the inspiratory process, which decreases exponentially with the inspiratory time until the end of the inspiratory process.…”
