[Application and related research of a modified fast-tracking PACU discharge assessment tool in the field of bone oncology].

To evaluate the effectiveness of the modified post anesthesia care unit (PACU) discharge assessment tool in the field of bone oncology, in order to prevent and reduce postoperative adverse events in patients undergoing bone tumor surgery. This is a prospective controlled study. 81 bone tumor patients who underwent general anesthesia surgery in the PACU from January to December 2023 were prospectively selected as the study subjects. They were randomly divided into a control group and an intervention group using a random number table method, with 43 and 38 cases, respectively. The control group and intervention group respectively used the fast track scoring system and the improved fast track scoring system as exit assessment tools. Independent sample t-test was used to compare the duration of PACU stay, mean arterial pressure (MAP) at PACU exit, heart rate, and blood oxygen saturation (SpO₂) between two groups of patients. Chi square test was used to compare the occurrence of adverse events between the two groups. The results showed that there was no statistically significant difference between the intervention group and the control group in terms of PACU dwell time [(55.58±23.83) min vs. (46.14±21.87) min], MAP at PACU [(88.23±11.52) mmHg vs. (86.25±10.62) mmHg], heart rate [(86.25±10.62) beats/min vs. (72.93±18.86) beats/min], and SpO₂ [(99.84±0.68)% vs. (99.86±0.91)%] (t=1.859, 0.805, 1.003, 0.101,all P>0.05). The total incidence of adverse events in the intervention group was significantly lower than the control group (68.42% vs. 90.70%, χ²=4.988, P<0.05). In conclusion, the modified fast-tracking criteria can significantly reduce the incidence of adverse events in PACU patients undergoing bone tumor surgery, but does not affect PACU dwell time and patient circulatory status.
