Methods: Ninety patients with laparoscopic cholecystectomy were randomly and equally divided into 3 groups (PC group, VC group and PRVC group). Esophageal pressure (PES), mean airway pressure (PAWM), peak airway pressure (PAP), arterial blood carbon dioxide partial pressure (PaCO2), end-tidal carbon dioxide concentration in the expired air (ETCO2), tidal volume (TV), mean arterial pressure (MAP) and heart rate (HR) were not only detected before pneumoperitoneum, but also in 5, 10, 15 and 20 minutes after pneumoperitoneum. Results: PES after pneumoperitoneum in VC mode was obviously higher than that in PC and PRVC groups. In 10 minutes after pneumoperitoneum, levels of PaCO2 and ETCO2 became increased obviously in PC and VC groups (p < .05);levels of PaCO2 and ETCO2 were not only increased in PC group, but also the level of TV after pneumoperitoneum in PC group was significantly lower than that in the other two groups (p < .05). Levels of PaCO2 and ETCO2 were increased in PC and VC groups after pneumoperitoneum, along with the increase of MAP and HR (p < .05). After pneumoperitoneum, levels of MAP and HR in PRVC group were significantly lower than those in PC and VC groups (p < .05). Conclusions: PRVC mode can effectively reduce the pneumoperitoneum-induced increase of PAWM, PAP and PES without the unusual increase of PaCO2 and ETCO2 during surgery, so as to guarantee the stability of vital signs in perioperative patients.展开更多

Methods: a total of 90 patients who received cardiopulmonary resuscitation due to cardiac arrest in the emergency department of our hospital from 2016 to 2020 and were eligible for the study were selected. All patients received standard chest compressions using Sabo c1007 , and the mechanical ventilation mode was selected: The experimental group used PRVC (pressure regulation volume control), control group 1 using VSV (volume support ventilation), control group 2 using PSV (pressure support ventilation), observe the basic conditions of the three groups of patients, the success rate of resuscitation (ROSC success rate), after successful cardiopulmonary resuscitation Respiratory mechanics indexes and blood gas analysis results were analyzed and compared using statistical methods. Results: (1) There was no statistical significance in the comparison of the basic conditions of the patients in each group. (2) The number of successful resuscitations in the experimental group was higher than that in the control group 1 and the control group 2, and the difference was statistically significant (P0.05, χ27.569). (3) The PaO2 and OI of the experimental group were higher than those of the control group 1 and the control group 2, and the differences were statistically significant (F19.604, 103.576, P0.001), and the CVP and PIP of the experimental group were lower than those of the control group 1, There were statistically significant differences between the two control groups (F7.82, 10.731, both P0.05). There was no significant difference in PaCO2 and MAP between the groups (all P>0.05). Conclusion: PRVC can improve the resuscitation success rate of patients with respiratory and cardiac arrest, and the PRVC mode has a good ability to maintain the patients tidal volume and blood oxygen saturation during cardiopulmonary resuscitation. After successful resuscitation, the patients human-machine coordination is good. It has a higher improvement on PaO2 and OI.展开更多
