RESUMO
@#Introduction: Lateral epicondylitis is a common condition causing severe incapacitating pain. Several methods of treatment have been approached for its management. In our study we aim to compare the results of injecting steroid and lignocaine mixture via single injection and peppered injection technique and analyse the outcome in each category. Materials and methods: A prospective randomised study comprising of 25 patients in each group (single vs peppered group) were included in the study after satisfying inclusion and exclusion criteria. Outcome of the treatment was measured in the form of Patient Related Tennis Elbow Evaluation (PRTEE) Questionnaire, Visual analogue score (VAS) and tenderness grading at two weeks, six weeks and six months after injection. Results: Results of our study showed that the mean PRTEE score was 22.36, 18.40 and 14.16 at 2 weeks, 6 weeks and 6 months following peppered injection as compared to 28.96, 21.84 and 25.32 in the single injection group (p value <0.05). VAS score at 2 weeks, 6 weeks and 6 months after the peppered injection was found to be 2.72, 1.72 and 1.36 and in the single injection group was 2.96, 1.92 and 2.72 at 2weeks, 6 weeks and 6 months, respectively (p value <0.05). On comparison of the 2 groups, there was a significant reduction of VAS scores at 6 months post-injection (p value <0.05) and PRTEE score at 6 weeks, 6 months in peppered injection group. Conclusion: The effects of peppered injection technique is seen to be advantageous over the single injection technique in the management of chronic lateral epicondylitis.
RESUMO
Objective To investigate the efficacy of the single-injection technique of PECS Ⅰ and Ⅱ blocks for postoperative analgesia in patients undergoing modified radical mastectomy. Methods Sixty female patients who would undergo elective unilateral modified radical mastectomy, aged 30-65 years, falling into ASA physical status Ⅰ or Ⅱ, were selected and randomly divided into PECS group (group P) or control group (group C), 30 cases in each. After induction, patients in group P underwent ultrasound-guided combined PECS Ⅰ and Ⅱ blocks in a single-injection technique before surgery, 30 ml of 0.5％ ropivacaine was given to these patients. Patients in group C received general anesthesia alone. Anesthesia maintenance was performed by total intravenous anesthesia. The dosage of intraoperative propofol and remifentanil, postoperative recovery time, the requirement of sufentanil at 48 h after operation and the first time pressing the analgesic pump button, rescue analgesic requirements at 48 h after operation and the pressing frequency of analgesic pump were recorded in the two groups. Results The usage of propofol and remifentanil in group P were significantly less than those in group C (P ＜ 0.05). The recovery time after operation was significantly shorter than that in group C (P ＜ 0.05). The total consumption of sufentanil after 48 h was significantly less than that in group C (P ＜ 0.05). The first pressing time of the analgesic pump in group P was significantly later than that in group C (P ＜ 0.05).The rescue analgesic requirements in group P at 48 h were lower than those in group C (P ＜ 0.05).The pressing frequencies of analgesic pump in group P at 24 h were less than those in group C (P ＜ 0.05). Conclusion For patients undergoing modified radical mastectomy, ultrasound-guided combined PECS Ⅰ and Ⅱ blocks in a single-injection technique can reduce the dosage of opioid drugs in the perioperative period, and can provide better analgesic effect after operation.
