Objective To explore the effect of the nurse-based

anesthesiologist and specialist-supervised acute pain services（NBASS-APS） in postoperative analgesic care for children with severe craniocerebral injury.Methods Sixty-eight children with severe craniocerebral injury admitted to a hospital in Zhumadian from January 2018 to June 2020 were selected as subjects and divided into experimental and control groups according to the random lottery grouping method

with 34 cases in each group.The children in the control group received conventional care

and the children in the experimental group received NBASS-APS care

and subjects in both groups were continuously cared for 4 weeks.The postoperative pain and complications were compared between the two groups

the postoperative signs were compared between the two groups at 3 d

and the Fugl-Meyer motor function assessment（FMA） scores were compared between the two groups at the time of admission

2 weeks and 4 weeks of care.Results The percentage of children with mild postoperative pain in the experimental group was higher than that in the control group

and the percentage of children with moderate and severe pain were lower than that in the control group

and the differences were statistically significant（P <0.05）.The mean arterial pressure

intracranial pressure

heart rate and jugular venous oxygen saturation of children in the experimental group were all lower than those in the control group at 3 d after surgery

and the differences were statistically significant（P<0.05）.The difference between the Fugl-Meyer scores of the two groups at the time of admission was not statistically significant（P>0.05）;the Fugl-Meyer scores of the two groups at 2 weeks and 4 weeks of care were higher than those at the time of admission

and the experimental group had higher scores than the control group

with statistically significant differences（P<0.05）.The incidence of postoperative complications in the children in the experimental group was 11.76%

which was lower than that in the control group（35.29%）

with statistically significant differences（P<0.05）.Conclusion The application of NBASS-APS in children with severe craniocerebral injury can effectively relieve their postoperative pain

improve physical signs

promote the recovery of motor function

and reduce the incidence of postoperative complications

which can be promoted in clinical practice.
