Objective To explore the application effect of CO₂ pneumoperitoneum pressure stage management in Da Vinci robot-assisted partial nephrectomy, and to provide reference for relevant personnel. Methods By convenient sampling, 40 patients who needed Da Vinci robot assisted partial nephrectomy in our hospital were randomly divided into control group and observation group. The control group used constant (13mmHg) CO₂ pneumoperitoneum pressure during the operation, and the observation group adjusted CO₂ pneumoperitoneum pressure according to the operation node: the adjusted pressure during the tissue free period was 13mmHg; The regulated pressure was 15 mmHg during hot ischemia. The regulating pressure during ischemia-reperfusion period was 9 mmHg; Blood pressure, heart rate, hot ischemia time, end-expiratory CO₂ partial pressure, hot ischemia time, intraoperative blood loss, postoperative drainage volume, and urine volume 24 hours after surgery were recorded respectively. Results The thermal ischemia time and intraoperative blood loss were significantly compared between the two groups (P< 0.01). The postoperative drainage volume was statistically significant (P< 0.05). Conclusion The application of CO₂ pneumoperitoneum pressure in Da Vinci robot-assisted partial nephrectomy can effectively shorten the time of hot ischemia, reduce intraoperative bleeding and postoperative drainage flow, and bring benefits to patients, which is worthy of clinical promotion.
