Abstract:Objective To explore the effect of pentazocine on anesthesia and incidence of catheter-related bladder discomfort (CRBD) in patients undergoing craniocerebral surgery.Methods A total of 120 patients undergoing craniocerebral surgery in our hospital from January 2021 to December 2022 were selected. They were divided into the observation group and the control group by the random number table method, with 60 cases in each group. All patients underwent general anesthesia, and the observation group was given pentazocine after the surgery while the control group was given the same amount of normal saline. The mean arterial pressure (MAP), systolic pressure (SBP), diastolic pressure (DBP), heart rate (HR) and oxygen saturation (SpO2) before extubation (T1), immediately after extubation (T2), 5 minutes after extubation (T3) and 10 minutes after extubation (T4) were observed. The differences in the Ramsay Sedation Scale score and the agitation score during early recovery from general anesthesia and the incidence of CRBD between the two groups were analyzed.Results MAP, SBP, DBP, HR, and SpO2 at T1, T2, T3 and T4 in the observation group and the control group were compared, and the results revealed that there was no significant difference in these indicators among the time points (P > 0.05) or between the observation group and the control group (P > 0.05). The change trends of MAP, SBP, DBP, HR, and SpO2 were also not different between the two groups (P > 0.05). The percentages of patients with 2 to 4 points of the Ramsay Sedation Scale and 0 to 1 point of the agitation score during early recovery from general anesthesia in the observation group were significantly higher than those in the control group (P < 0.05). The incidence of CRBD in the observation group was lower than that in the control group (P < 0.05), and the severity of CRBD in the observation group was lower than that in the control group (P < 0.05). The incidence of headache in the observation group was significantly lower than that in the control group (P < 0.05).Conclusions Pentazocine is effective for sedation during the craniocerebral surgery and reduces the incidence of CRBD with few adverse reactions.
