Abstract:
Objective:To explore the feasibility and advantages and disadvantages of local anesthesia for TiRobot-assisted removal of sacroiliac screws by comparison with general anesthesia for TiRobot-assisted removal of sacroiliac screws.Methods:A retrospective study was performed in 39 patients with posterior pelvic ring fracture-dislocation who had undergone removal of percutaneous sacroiliac screws after fracture union from January 2017 to December 2020 at Department of Orthopaedic Surgery, Hospital Affiliated to Chengdu University. Their sacroiliac screws were removed with TiRobot assistance under local anesthesia (LA group) or general anesthesia (GA group). In the LA group of 18 cases, there were 10 males and 8 females, aged (43.3 ± 8.4) years (from 25 to 58 years); in the GA group of 21 cases, there were 12 males and 9 females, aged (44.9 ± 9.0) years (from 23 to 60 years). The 2 groups were compared in terms of time for planning screw removal path, fluoroscopy frequency, fluoroscopy time, operation time, anesthesia time, anesthesia cost, postoperative visual analogue scale (VAS) and postoperative ambulation time.Results:There was no statistically significant difference in baseline data between the 2 groups, showing comparability ( P>0.05). Follow-ups revealed grade A wound healing in all patients. There were no significant differences between the 2 groups in time for planning screw removal path, fluoroscopy frequency, fluoroscopy time or operation time ( P>0.05). The anesthesia time [(41.6 ± 8.3) min], anesthesia cost [(653.5 ± 102.6) yuan] and postoperative ambulation time [(2.6 ± 0.6) h] in the LA group were significantly less than those in the GA group [(52.3 ± 9.5) min, (2,475.6 ± 261.8) yuan and (8.7 ± 2.4) h] while the VAS score in the former group (3.8 ± 1.5) was significantly higher than that in the latter group (2.5 ± 1.3) (all P<0.05). Conclusions:It is feasible to use local anesthesia for TiRobot-assisted removal of sacroiliac screws. In TiRobot-assisted removal of sacroiliac screws, compared with general anesthesia, local anesthesia may lead to shorter anesthesia time, lower anesthesia cast and shorter ambulation time, but the patients need to be compliant enough.
