The efficacy of local anaesthetic for pain after iliac bone harvesting: a randomised controlled trial

Efficacy of local pain management strategies for patients undergoing anterior iliac crest bone harvesting: a systematic review

Anterior Iliac crest bone harvesting (AICBH) is a common surgical procedure with applications in various medical specialties, but it is often accompanied by significant postoperative pain. Effective pain management is therefore essential for optimising patient outcomes. This systematic literature review aimed to evaluate the effectiveness of local donor site pain management interventions in AICBH procedures. It followed the Cochrane Handbook for Systematic Reviews of Interventions version 6.4 guidelines and adhered to the PRISMA 2020 statement for comprehensive and high-quality reporting. A comprehensive search was conducted across PubMed, Cochrane, and Embase to identify relevant studies. Inclusion criteria encompassed randomised controlled trials assessing pain management strategies in AICBH patients. The methodological quality of the included studies was assessed using the Jadad scale. Data extraction focused on medication types, administration modes, pain scores, and use of narcotics. Fourteen eligible studies were included. Methodological quality varied, with most studies demonstrating a low risk of bias. Medication types included amide and opioid groups, administered via single-shot injections or infusion systems. Results indicated that indwelling iliac crest catheters with bupivacaine showed significant postoperative reductions in pain scores and narcotics use compared with other techniques. The findings suggest that use of an indwelling catheter with bupivacaine is an effective pain management strategy for AICBH patients. However, heterogeneity among the studies and a lack of standardised methodologies pose limitations. Further homogeneous and standardised studies are therefore needed to strengthen the evidence base and inform clinical practice.

It's Hip to Go Home: An Evaluation of Outpatient Alveolar Bone Grafting in Patients With Cleft Palate

INTRODUCTION

Secondary alveolar bone grafting (ABG) is a common procedure performed at cleft care centers used to fill the alveolar cleft. The advent of techniques such as minimally invasive trephine drill harvest and placement of continuous-infusion pain pumps at the donor site has made outpatient ABG an increasingly feasible and cost-effective procedure. However, enhanced recovery after surgery protocols to maximize pain control and recovery times for this patient population have not been well established.

METHODS

A retrospective single-institution review was conducted of pediatric patients with cleft palate who underwent iliac crest bone graft ABG at a large urban academic children's hospital from 2017 to 2022. Patient age, alveolar cleft repair laterality, pain scores, surgery duration, hospital LOS, readmissions, and re-operations within 30 days were examined.

RESULTS

Fifty-four patients met our inclusion criteria. Fifty patients (92.6%) received a pain pump during the operation. The median duration of surgery and LOS in the post-anesthesia care unit were 1.28 and 1.75 hours, respectively. Fifty-two patients (96.3%) were discharged on the same day as their surgery whereas 2 patients (3.7%) stayed in the hospital overnight. The median pain score at the time of discharge was 0 (interquartile range 0, 0). There were 6 (11.1%) minor complications including 5 pain pump malfunctions and 1 recipient site wound breakdown. There was 1 readmission (1.9%) for development of a surgical site infection at the hip and no re-operations within 30 days of surgery.

CONCLUSION

The described outpatient ABG protocol demonstrates effective postoperative pain control, short hospital LOS, and few complications requiring hospital readmission or reoperation.

A Review of Wound Infusion With Local Anesthetics in Plastic Surgery

BACKGROUND

Suboptimal pain management is a common, yet largely unrecognized, problem in the postsurgical patient population. Current treatment protocols heavily rely on opioid use and, though generally effective in providing pain relief, are associated with multiple side effects. The present systematic review aims to offer plastic surgeons insight into the current state of literature on prolonged local anesthetic wound infusion regimens, evaluating both their efficacy in lowering pain scores and the potential opioid-sparing effect.

METHODS

A comprehensive literature search of the Medline, Embase, and Cochrane Library databases was performed to identify relevant studies published between 1980 and December 2017 evaluating the use of prolonged local anesthetic wound infusion for postoperative pain management in plastic surgery.

RESULTS

A total of 28 articles were selected, including 3904 patients. The overall infection rate in all patients treated with postsurgical local anesthetic wound infiltration was 0.28% (7/2536). There were no reported cases of systemic toxicity. An opioid-sparing effect was found in 92% (12/13) of studies when compared to an active comparator and 88% (7/8) of those comparing to placebo. Pain scores were decreased in 90% (9/10) of studies comparing wound infiltration to narcotic-based regimens and in 67% (6/9) of those comparing to placebo.

CONCLUSIONS

Continuous or intermittent wound infusion is safe and effective in reducing pain scores and opioid consumption in plastic surgery. Though the overall pain-lowering effect appears to be modest, ease of catheter insertion and patient satisfaction make this technique an alluring alternative to more validated approaches such as neuraxial or peripheral nerve blocks.

Gait Analysis of Patients Subjected to the Atrophic Mandible Augmentation with Iliac Bone Graft

In this study, we aimed to quantitatively monitor and describe the gait functions of patients, who underwent iliac crest bone grafting in atrophic jaw augmentation operation, by taking into account the alterations of gait parameters and muscle forces in the early recovery course. To do so, temporospatial and kinematic gait parameters of ten patients during pre- and postoperative periods were recorded, and forces of the gluteus medius, gluteus maximus, and iliacus muscles were calculated. Three postoperative periods were specified as one week (post-op1), two weeks (post-op2), and three weeks (post-op3) after the surgery. Restoring process of the gait patterns was comparatively evaluated by analyzing the gait parameters and muscle forces for pre- and postoperative periods. Temporospatial and kinematic parameters of post-op3 were closer to those obtained in pre-op than those in post-op1 and post-op2 (p < 0.05). Muscle forces calculated in post-op3 showed the best agreement with those in pre-op among the postoperative periods in terms of both magnitude and correlation (p < 0.05). In conclusion, the patients began to regain their preoperative gait characteristics from the second week after surgery, but complete recovery in gait was observed three weeks after the surgery.

Chronic Morbidity of a Pilot Hole Burr Technique for Anterior Iliac Crest Autograft in Cervical Fusion

Anterior cervical decompression and fusion is a commonly performed procedure for cervical pathology. Graft choices include autograft, allograft, xenograft, synthetic, or a combination. Autograft has been shown to increase fusion rate compared with allograft, yet high morbidity at the harvest site has been reported. Few studies have evaluated chronic graft site pain, and to the authors' knowledge, no study has evaluated morbidity of a pilot hole burr technique for anterior iliac crest harvest. The objective of this study was to evaluate chronic morbidity of anterior iliac crest harvest in anterior cervical decompression and fusion using a pilot hole burr technique. A phone survey was used to identify chronic morbidity. Number of levels fused, age, sex, and acute graft site complications were explored to evaluate impact of patient characteristics on chronic graft site pain. A total of 140 patients met inclusion criteria; 106 patients (76%) completed the phone survey. Mean follow-up was 38.9 months. Two patients (1.9%) reported current and constant graft site pain. Nine patients (8.5%) reported intermittent pain. Average numeric pain rating scale score for survey participants was 0.25 of 10. No patients were taking narcotics for graft site pain. Two patients (1.9%) reported functional impairment secondary to the graft site pain. There was no impact of number of levels fused, age, sex, or acute graft site complications on chronic graft site pain. The pilot hole burr technique resulted in low long-term morbidity and may offer an alternative to traditional methods for those wishing to use autologous graft in anterior cervical decompression and fusion.

A Multimodal Preemptive Analgesic Protocol for Alveolar Bone Graft Surgery: Decreased Pain, Hospital Stay, and Health Care Costs

OBJECTIVE

To evaluate postoperative pain, hospital length of stay (LOS), and associated costs of multiple perioperative analgesic strategies following alveolar bone grafting (ABG).

DESIGN

Retrospective comparative cohort study.

SETTING

Tertiary care pediatric hospital.

PATIENTS/PARTICIPANTS

Iliac crest bone graft (ICBG) harvest techniques: "Open Harvest" (n = 22), "Trephine Only" (n = 14), or "Trephine + Pain Pump" (n = 25).

INTERVENTION

The "Open Harvest" group underwent open ICBG harvest with 3-walled osteotomies. For the other 2 treatment groups, a trephine drill was used to harvest iliac crest bone with a ropivacaine infusion pump into the hip donor site ("Trephine + Pain Pump") or without ("Trephine Only"). Patients who underwent ABG with only cadaveric allograft were analyzed as a comparison group ("No Harvest").

MAIN OUTCOMES MEASURES

Outcomes were planned prior to data collection: maximum pain score, hospital LOS, and associated health care costs.

RESULTS

Maximum pain scores were significantly higher in the "Open Harvest" group (7.3/10) compared to "Trephine + Pain Pump" (1.8/10; P < .0001) and "No Harvest" groups (2.8/10; P < .01). Hospital LOS decreased from 2.4 days ("Open Harvest") to 0.5 days (Trephine + Pain Pump"; P < .0001). Twelve (48%) patients from "Trephine + Pain Pump" were discharged on the day of surgery. The "Trephine + Pain Pump" saved an estimated $5336 for a unilateral ABG and $7265 for a bilateral ABG compared to "Open Harvest."

CONCLUSIONS

The combined use of the trephine ICBG technique and ropivacaine infusion catheter effectively decreased pain, shortened hospital stay, and improved cost saving compared to patients who have undergone other methods of ICBG.

Postoperative pain following posterior iliac crest bone graft harvesting in spine surgery: a prospective, randomized trial

BACKGROUND CONTEXT

Postoperative pain at the site of bone graft harvest for posterior spine fusion is reported to occur in 6%-39% of cases. However, the area around the posterior, superior iliac spine is a frequent site of referred pain for many structures. Therefore, many postoperative spine patients may have pain in the vicinity of the posterior iliac crest that may not in fact be caused by bone graft harvesting. The literature may then overestimate the true incidence of postoperative iliac crest pain.

PURPOSE

We performed a prospective study testing the hypothesis that patients will not report significantly higher visual analog scores over the graft harvest site when compared with the contralateral, non-harvested side.

STUDY DESIGN/SETTING

This is a prospective, randomized cohort study.

PATIENT SAMPLE

Patients aged 18-75 years undergoing elective spinal fusion of one to two levels between L4 and S1 for spinal stenosis and spondylolisthesis were randomized to left-sided or right-sided iliac crest bone graft (ICBG) donor sites and blinded to the side of harvest.

OUTCOME MEASURES

Primary outcome was a 10-point visual analog scale (VAS) for pain over the left and right posterior superior iliac spine.

METHODS

Bone graft was harvested via spinal access incisions without making a separate skin incision over the crest. Each patient's non-harvested side served as an internal control. Data points were recorded by patients on their study visit sheets preoperatively and at 6 weeks, 3 months, 6 months, and 1 year postoperatively.

RESULTS

Forty patients were enrolled in the study (23 females) with an average follow-up of 8.1 months (1.5-12 months). Mean age was 51.7 years (23-77 years). Left- and right-side ICBG harvesting was performed equally between the 40 patients. The average volume of graft harvested from the left was 35.3 mL (15-70 mL) and 36.1 mL (15-60 mL) from the right. There was no statistical difference between preoperative VAS score on the harvested side compared with the non-harvested side (p=.415). Postoperatively, there were consistently higher VAS scores on the operative side; however, these differences were not statistically significant at 6 weeks (p=.111), 3 months (p=.440), 6 months (p=.887), or 12 months (p=.240). Both groups did, however, show statistically significant improvements in VAS scores over time within the operative and nonoperative sides (p<.05). Graft volume had no effect on the VAS scores (p=.382).

CONCLUSIONS

The current literature does not adequately illuminate the incidence of postoperative pain at the site of harvest and the relative magnitude of this pain in comparison with the patient's residual low back pain. This is the first study to blind the patient to the laterality of bone graft harvesting. Our randomized investigation showed that although pain on the surgical side was slightly higher, it was neither clinically nor statistically different from the nonsurgical side. Our conclusion supports surgeons' use of autologous bone graft, which offers a cost-effective, efficacious spinal fusion supplement.

Cost Savings from Reducing Pain Through the Delivery of Integrative Medicine Program to Hospitalized Patients

OBJECTIVES

An important task facing hospitals is improving pain management without raising costs. Integrative medicine (IM), a promising nonpharmacologic pain management strategy, is yet to be examined for its cost implications in an inpatient setting. This institution has had an inpatient IM department for over a decade. The purpose was to examine the relationship between changes in patients' pain, as a result of receiving IM therapy, and total cost of care during an inpatient hospital admission.

DESIGN

In this retrospective analysis, data from an EPIC-based electronic health record (EHR) patient demographics, length of stay (LOS), and All Patient Refined Diagnosis Related Groups (APR-DRG) severity of illness measures were utilized. IM practitioners collected and entered patient-reported pain scores into the EHR. The authors regressed the demographic, change in pain, LOS, and APR-DRG variables with changes in pain on total cost for the hospital admission. To estimate cost savings to the hospital, they computed the average reduction in cost associated with reduction in pain by multiplying the coefficient for change in pain by average total cost.

SETTING/LOCATION

A large, tertiary care hospital in Minneapolis, MN.

SUBJECTS

Adult inpatient admissions, 2730, during the study period where patients received IM for pain and met eligibility criteria.

INTERVENTION

IM services provided to inpatients.

OUTCOME MEASURES

Change in pain on an 11-point numeric rating scale before and after initial IM sessions; total costs for hospital admissions.

RESULTS

Both LOS and age were found to increase cost, as did being white, male, married, and having APR-DRG severity coded as extreme. For patients receiving IM therapies, pain was reduced by an average of 2.05 points and this pain reduction was associated with a cost savings of $898 per hospital admission.

CONCLUSIONS

For patients receiving IM therapies, pain was significantly reduced and costs were lowered by about 4%.

Use of the On-Q Pain Pump in Alveolar Bone Grafting: Effect on Hospit Length of Stay

Objective

Alveolar bone grafting (ABG) with iliac crest bone graft can be associated with significant pain at the donor site. The On-Q pain pump has been shown to be efficacious in treating postsurgical pain. The aim of this study was to compare the length of postoperative hospital stay in patients undergoing ABG who received the On-Q pain pump at the iliac crest donor site (On-Q+) with that of patients who did not receive the On-Q pain pump (On-Q-).

Design

A retrospective, cohort study, approved by institutional review board, was performed. Thirty-one consecutive patients in the On-Q- group were compared with 38 consecutive patients in the On-Q– group. The two cohorts were assessed for length of stay. Statistical analysis was performed using the Fisher exact probability test.

Setting

Tertiary care academic medical center.

Patients

Sixty-nine patients with cleft lip and/or cleft palate (CL/P) undergoing secondary ABG with iliac crest bone graft were operated on between May 1993 and January 2014.

Main Outcome Measure

Length of postoperative hospital stay.

Result

Mean length of stay in the On-Q– patients was 0.52 days versus 0.37 days for the On-Q– patients. This difference between the two cohorts was not statistically significant (P = .234).

Conclusion

Although there is a trend toward a shorter length of stay in our patients who received the On-Q pump, this finding was not statistically significant. Given the expense and additional burden of care associated with the device, we have become more selective in its utilization.

Continuous postoperative pain control using a multiple-hole catheter after iliac bone grafting: comparison between ropivacaine and levobupivacaine

The aim of this study was to compare the analgesic effects of ropivacaine and levobupivacaine in continuous infiltration anaesthesia delivered via a multiple-hole catheter for the purpose of postoperative analgesia after iliac bone grafting. Thirty-four patients scheduled for iliac bone grafting in the maxillofacial region participated in this study. The patients were randomized to a ropivacaine group (Ropi group) and a levobupivacaine group (Levo group). After harvesting the iliac bone for grafting, a multiple-hole catheter was placed on the periosteum of the iliac bone. When surgery was completed, continuous administration was started at 4 ml/h of 0.2% ropivacaine (Ropi group) or 0.25% levobupivacaine (Levo group). Pain was evaluated in the recovery room and at 4h after surgery, as well as at 9:00 and 18:00 on postoperative days 1, 2, and 3, using a visual analogue scale. Side effects were also recorded. No significant difference in the visual analogue scale scores at rest or in motion was observed between the two groups. In addition, there were no side effects in the two groups. Both 0.2% ropivacaine and 0.25% levobupivacaine provided comparable analgesic effects in continuous infiltration anaesthesia delivered via a multiple-hole catheter after iliac bone grafting.

Efficacy of bilateral mental nerve block with bupivacaine for postoperative pain control in mandibular parasymphysis fractures

Background and aims. Postoperative pain control is extremely important for both patients and surgeons; in this context, long-acting local anesthesia can play an important role after open reduction of maxillofacial fractures. The purpose of this study was to evaluate the effect of bilateral mental nerve block with bupivacaine on postoperative pain control in mandibular symphyseal fractures.

Materials and methods. Fifty patients with pure mandibular symphyseal fractures were studied in two control and study groups. In contrast to the control group, the study group received bilateral mental nerve block with bupivacaine postoperatively. Patients were examined in relation to pain severity and opioid analgesic drug need sequences.

Results. The study group needed significantly less opioid than the control group (P<0.01, U=141). The control and study groups were different in first opioid administration time. The control and study groups received first opioid dose in 0-2 and 2-4 hours, respectively.

Conclusion. Bilateral mental nerve blocks with bupivacaine can reduce opioid analgesic need and it has a positive effect on postoperative pain control in mandibular symphyseal fractures.

Pain from donor site after anterior cervical fusion with bone graft: a prospective randomized study with 12 months of follow-up

INTRODUCTION

Harvesting bone graft from the iliac crest in spinal fusion surgery is a widely used technique. However, complications can occur and there are also reports of patients with persistent graft site pain after surgery. The aim of this study was to evaluate pain from the donor site (DS) over time, and register associated complications and if it affected health-related quality of life (HRQoL).

MATERIAL AND METHODS

One hundred and seven patients participating in an RCT between two different methods of reconstruction after cervical decompression were included in this study. One group underwent surgery with bone graft (BG) from the iliac crest and the other with no bone graft (NBG). All patients were evaluated concerning pain at DS and HRQoL preoperatively, at 4 weeks, 3 months and 1 year. Pain was evaluated with visual analog scale (VAS) and HRQoL with EQ-5D.

RESULTS

A statistically significant difference was found at all times of follow-up in the BG group compared to preoperative levels and the NBG group. The VAS levels at follow-ups at 3 months and 1 year were however of questionable clinical importance. Two patients in the BG group had superficial wound infections postoperatively and five patients still had sensory disturbance in the area of graft site at 12 months. No major complications were registered. No difference could be seen in EQ-5D at any time of follow-up between the groups.

CONCLUSION

Harvesting of iliac crest bone graft is associated with significant pain. However, at 3 months postoperatively, the negative effect of clinical importance seemed to have disappeared compared to when no bone graft was harvested. The pain from bone graft harvesting does not seem to affect the quality of life at 4 weeks postoperatively and onward.
