Abstract

Background: Solutions lower than 5% lidocaine have been recommended for spinal anesthesia. Thus, several solutions ranging from 0.5% to 3% lidocaine in glucose have been used. We designed this retrospective study in patients operated on in gynecological, general and urological surgery in the supine position with 60 mg of 1.5% lidocaine in glucose.

Methods: A total of 210 patients were retrospectively evaluated after receiving a fixed dose of 60 mg of 1.5% hyperbaric lidocaine. Patients were examined for latency of analgesia, cephalad spread, sensory block, motor block, duration of surgery, block duration, and cardiocirculatory and neurological complications.

Results: The baricity of 1.5% lidocaine glucose is hyperbaric. All patients were successfully operated on in the horizontal dorsal position, and there were no anesthesia failures. The cephalad spread mode of analgesia was between T10 at 5 minutes, T9 at 10 minutes and T8 at 15 minutes, every 5 minutes the cephalic spread increased by one level of sensory blockade. Complete motor block (grade 3) occurred in 70% of patients at 15 minutes. Eight (3.8%) patients presented bradycardia, and 19 (9%) patients presented hypotension. The transient neurological symptoms no were reported by telephone after discharge until the 3rd postoperative day.
Conclusion: This study showed that 60 mg of 1.5% lidocaine hyperbaric solution for spinal anesthesia for gynecological, inguinal and umbilical hernia repair, urological short-term surgery with subarachnoid puncture in left lateral decubitus and surgery was performed in horizontal dorsal decubitus, facilitates discharge of outpatients within a few hours while decreasing recovery room time and nursing care.
