ABSTRACT
Objective:
To evaluate the influence of intertransverse septal anesthetic block (BASIT) on postoperative pain in lumbar spine surgery.
Methods:
The study was carried out prospectively and observationally. Were included 105 patients who underwent posterior lumbar spine surgery, divided into two groups: 35 patients in the experimental group, who received BASIT at the end of the procedure, and 70 patients in the control group, without BASIT. Patients were assessed for low back pain (visual pain scale), opioid consumption on the 1st postoperative day, complications related to the procedure, and length of stay after surgery.
Results:
The sample consisted of 46 men and 59 women, with a mean age of 57.7 years (21 to 90 years). Mean postoperative pain in the experimental group was 1.88, and in the control group 2.11 (p<0.05). There was a trend towards less morphine use in the experimental group with p = 0.053. There was a statistical difference in morphine consumption between patients who did not previously use opioids and those who already used them (p 0.04). There was no difference between the groups regarding length of stay.
Conclusion:
Anesthetic blockade of the intertransverse septum reduced the consumption of opioids and the levels of low back pain after surgery (p<0.05), with no statistical difference in length of hospital stay or complications related to the technique. Level of Evidence II; Clinical Prospective Study.
