Local anesthesia for inguinal hernia repair in adolescents

Improving patient outcomes with inguinal hernioplasty-local anaesthesia versus local anaesthesia and conscious sedation: a randomized controlled trial

PURPOSE

Conscious sedation is regularly used in ambulatory surgery to improve patient outcomes, in particular patient satisfaction. We hypothesized that the addition of conscious sedation would provide greater patient satisfaction with inguinal hernioplasty compared to local anesthesia alone.

METHODS

This trial was a single-centre, randomized, placebo-controlled, double-blinded trial where patients undergoing inguinal hernioplasty using local anaesthesia were randomized to receive local anaesthesia alone versus local anaesthesia and conscious sedation. The primary outcome of patient satisfaction was assessed using the Iowa Satisfaction with Anesthesia Scale (ISAS). The study was powered to detect a significant difference in ISAS scores between groups. Comparisons were made using T test and Chi square tests. A p value of less than 0.05 was considered significant.

RESULTS

There were 149 patients randomized: 78 to the local anesthesia (LA) group and 71 to the local anaesthesia and conscious sedation (LACS) group. For the primary outcome measure of patient satisfaction, the mean ISAS score was significantly greater in the LACS group (p = 0.009). The experience of pain and pain severity was greater in the LA group (p = 0.016; p = 0.0162 respectively). No statistically significant difference was found between groups with respect to operative time, time to discharge or postoperative complications.

CONCLUSION

The use of conscious sedation with local anesthesia for inguinal hernioplasty is safe, results in less pain experience and severity and is associated with better patient satisfaction. The use of conscious sedation does not delay patient discharge.

Local Anesthesia Versus Local Anesthesia and Conscious Sedation for Inguinal Hernioplasty: Protocol of a Randomized Controlled Trial

Background

Conscious sedation is regularly used in ambulatory surgery to improve patient outcomes, in particular patient satisfaction. Reports suggest that the addition of conscious sedation to local anesthesia for inguinal hernioplasty is safe and effective in improving patient satisfaction. No previous randomized controlled trial has assessed the benefit of conscious sedation in this regard.

Objective

To determine whether the addition of conscious sedation to local anesthesia improves patient satisfaction with inguinal hernioplasty.

Methods

This trial is designed as a single-center, randomized, placebo-controlled, blinded trial of 148 patients. Adult patients diagnosed with a reducible, unilateral inguinal hernia eligible for hernioplasty using local anesthesia will be recruited. The intervention will be the use of intravenous midazolam for conscious sedation. Normal saline will be used as placebo in the control group. The primary outcome will be patient satisfaction, measured using the validated Iowa Satisfaction with Anesthesia Scale. Secondary outcomes will include intra- and postoperative pain, operative time, volumes of sedative agent and local anesthetic used, time to discharge, early and late complications, and postoperative functional status.

Results

To date, 171 patients have been recruited. Surgery has been performed on 149 patients, meeting the sample size requirements. Follow-up assessments are still ongoing. Trial completion is expected in August 2017.

Conclusions

This randomized controlled trial is the first to assess the effectiveness of conscious sedation in improving patient satisfaction with inguinal hernioplasty using local anesthesia. If the results demonstrate improved patient satisfaction with conscious sedation, this would support routine incorporation of conscious sedation in local inguinal hernioplasty and potentially influence national and international hernia surgery guidelines.

IS SAME-DAY INGUINAL HERNIA SURGERY POSSIBLE?

1-INTRODUCTION: The Lichtenstein hernia repair is associated with low recurrence rates and short operation times, and can be performed under local anaesthesia. Thus, this is among the most-preferred methods used in recent years. Our objective was to explore the same-day discharge rates, and the causes of delayed discharge and re-admission to hospital, of patients treated using the Lichtenstein repair method, to evaluate the feasibility of performing same-day hernia surgery in clinical practice. 2.

MATERIALS AND METHODS

. One hundredof a total of 236 patients diagnosed with unilateral inguinal or femoral hernias, who required surgical treatment, and who agreed with the conditions of the study, were prospectively included. All patients were treated using the Lichtenstein mesh repair method, under local anaesthesia between June 2006 and January 2008. We investigated the types and locations of hernias, duration of surgery, seniority of the surgeon, the feasibility of same-day surgery in subgroups stratified by ASA risk scores, and postoperative complication rates, in patients who underwent inguinal surgery under local anaesthesia 3. RESULTS , DISCUSSION AND CONCLUSIONS:. The rates of pain and post-operative complications were very low in hernia patients who underwent same-day surgery under local anaesthesia. The operation reduces the length of hospital stay and helps patients mobilise earlier. Both the literature, and our data, indicate that inguinal hernia repair under local anaesthesia is safe and effective, reducing anaesthesia-related complications and the length of hospital stay; is cost-effective; and is applicable in all patients.
