Effects of different CO2 pneumoperitoneum pressures on delirium and cognitive function after laparoscopic radical resection of rectal cancer in the elderly
pneumoperitoneum pressures during operation on delirium and cognitive function of elderly patients undergoing laparoscopic radical resection of rectal cancer.
Methods
2
A total of 92 elderly patients who underwent laparoscopic radical resection of rectal cancer were selected as the research subj
ects, and the patients were randomly divided into H group and L group, with 46 cases in each group. Patients in H group used CO
2
pneumoperitoneum pressure of 15 mmHg during surgery, while patients in L group used CO
2
pneumoperitoneum pressure of 11 mmHg during surgery. The cognitive function scores, postoperative delirium, blood gas analysis results, vital signs and adverse reactions during anesthesia awakening period of patients in the two groups were compared.
Results
2
The cognitive function scores 6 hours and 24 hours after surgery of patients in L group were significantly higher than those in H group (
P
<
0.05). The incidences of delirium 6 hours and 24 hours after surgery in L group were significantly lower than those in H group (
P
<
0.05). There was no statistically significant difference in mean arterial pressure (MAP), heart rate or pulse oxygen saturation (SpO
2
) before and after pneumoperitoneum of patients between the two groups (
P
>
0.05). There were statistically significant differences in pH and partial pressure of carbon dioxide (PaCO
2
) at the end of pneumoperitoneum of patients between the two groups (
P
<
0.05). The incidences of delayed awakening and agitation during the awakening period of patients in H group were significantly higher than those in L group (
P
<
0.05).
Conclusion
2
For elderly patients undergoing laparoscopic radical resection of rectal cancer, CO
2
pneumoperitoneum of 11 mmHg pressure has a smaller effect on postoperative cognitive function and a lower incidence of postoperative delirium and adverse reactions during the awakening period, which may be related to the level of PaCO
2
in the blood of patients, and should be paid attention to.
