| Objective To investigate the clinical effect of ultrasound guided femoral nerve-lateral femoral cutaneous nerve block combined with laryngeal mask general anesthesia in the treatment of femoral shaft fractures. Methods Thirty cases of femoral shaft fracture treated by Huangshan People's Hospital from September 2014 to May 2018 were selected,femoral and lateral femoral cutaneous nerve block combined with laryngeal mask general anesthesia were used, and 0.5% ropivacaine was injected with 15 mL and 0.375% ropivacaine with 5 mL to block lateral femoral cutaneous nerve.Then hemodynamic changes before nerve block(T0),and 5 min(T1), 10 min(T2), 15 min(T3), 30 min(T4) after nerve block were observed. The effect and duration of sensory and motor block was assessed. At the same time,adverse reactions such as nausea, vomiting and postoperative urinary retention were also observed. Results T0, T1, T2, T3, T4 systolic pressure was(144.67±14.81),(141.53±14.32),(141.67±13.88),(142.00±12.40),(145.00±11.65) mmHg, respectively, and there was no significant differenceat different time points (P>0.05). T0, T1, T2, T3, T4 diastolic pressure was(79.73±4.39),(77.90±4.29),(79.87±3.87),(78.77±4.29),(79.17±3.48) mmHg,respectively, and the difference at different points was not statistically significant(P>0.05). The heart rates of T0, T1, T2, T3, and T4 were(80.00±4.98),(78.90±3.21),(78.33±3.92),(79.33±3.02),(78.07±3.38) times/minute, and the difference between different points was not statistically significant(P>0.05). The average onset time of the patient sensory block was (6.77±0.90) min and the duration was(339.90±65.67) min. The average onset time of motion block was(12.23±2.28) min and the durationwas(213.00±39.08) min. No nausea, vomiting or postoperative urinary retention occurred in 30 patients. Conclusion Ultrasonically guided femoral nerve-lateral femoral cutaneous nerve block combined with laryngeal mask general anesthesia can be widely applied to the operation of femoral shaft fracture, with stable hemodynamics, long analgesia time and few complications. |
