Low-dose preoperative pregabalin improves postoperative pain management in septorhinoplasty surgery: a double-blind randomized clinical trial

Pain management following septorhinoplasty surgery: evidence from a systematic review

PURPOSE

We investigated recent evidence on the analgesics available for postoperative pain management among patients undergoing septoplasty or rhinoplasty surgery.

METHODS

Studies were retrieved from MEDLINE (through PubMed), Web of Science, and Embase up to 3 August 2022.

RESULTS

Forty-seven studies including 3717 patients were included. There were 45 randomized clinical trials and 2 observational cohort studies. Most of the studies were recently published and conducted in Turkey (n = 27). The majority of the studies performed the intervention preoperatively (n = 26), 11 studies postoperatively, 6 studies intraoperative, 2 studies preoperative plus intraoperative, and 2 studies performed the intervention with preoperative plus postoperative timing. The most evaluated medication was lidocaine (n = 10), followed by levobupivacaine (n = 4), and gabapentin (n = 4). Regarding post-operative pain assessment, the most used scale was the visual analog scale (VAS) (n = 36). Compared to controls, almost all interventions showed a significant benefit in managing post-operative pain. Although it should be mentioned regarding the comparison between opioids and NSAIDs consumption after surgery for pain management, most studies did not show a significant difference between the groups. No major side effects except nausea and vomiting were observed among the reviewed studies.

CONCLUSION

This study summarized the most recent options that are available to manage pain following septorhinoplasty surgery. Recent investigations showed local interventions vs pre/post-operative analgesic medications are highly suggested to be replaced with opioids and NSAIDs as they have shown prominent efficacy with no significant adverse events. Future research is advised to determine the best dosage and administration techniques.

The analgesic efficacy of ketamine for septorhinoplasty: a meta-analysis study

BACKGROUND

The analgesic efficacy of ketamine supplementation was not well-established for septorhinoplasty and this meta-analysis aimed to compare ketamine supplementation with placebo for the postoperative pain control of septorhinoplasty.

METHODS

We systematically searched several databases, including PubMed, EMbase, Web of science, EBSCO and Cochrane library databases, and included randomized controlled trials (RCTs) regarding the effect of ketamine supplementation versus placebo for pain control after septorhinoplasty. This meta-analysis was conducted by random effect model.

RESULTS

Five RCTs were included in this meta-analysis. In comparison with control group for septorhinoplasty, ketamine supplementation was associated with significantly decreased pain scores at 30 min (SMD = - 3.84; 95% CI = - 6.73 to - 0.96; P = 0.009), pain scores at 1 h (SMD = - 2.70; 95% CI = - 3.79 to - 1.61; P < 0.00001), pain scores at 2 h (SMD = - 1.83; 95% CI = - 3.01 to - 0.64; P = 0.003), rescue analgesics (OR = 0.08; 95% CI = 0.04 to 0.17; P < 0.00001), but unraveled no obvious impact on pain scores at 4 h (SMD = - 1.13; 95% CI = - 3.37 to 1.12; P = 0.32) or the incidence of nausea and vomiting (OR = 0.71; 95% CI = 0.30 to 1.72; P = 0.45).

CONCLUSIONS

Ketamine supplementation was effective to improve pain relief after septorhinoplasty.

The analgesic efficacy of pregabalin versus placebo for septorhinoplasty: A meta-analysis

BACKGROUND

The analgesic efficacy of pregabalin supplementation for septorhinoplasty remains elusive. This meta-analysis was conducted to compare pregabalin supplementation with placebo for the postoperative pain control of septorhinoplasty.

METHODS

We systematically searched several databases including PubMed, EMbase, Web of Science, EBSCO and Cochrane library databases, and included randomized controlled trials (RCTs) regarding the effect of pregabalin supplementation versus placebo for pain control after septorhinoplasty. This meta-analysis was conducted by fixed or random-effect model based on the heterogeneity.

RESULTS

Seven RCTs were included in this meta-analysis. In comparison with control group for septorhinoplasty, pregabalin supplementation was associated with significantly decreased pain scores at 1 h (standard mean difference [SMD] = -1.45; 95% confidence interval [CI] = -2.43 to -0.47; P = .004), pain scores at 2 hours (SMD = -1.01; 95% CI = -1.83 to -0.20; P = .02), pain scores at 6 hours (SMD = -1.00; 95% CI = -1.47 to -0.54; P < .0001), number of rescue analgesics (odd ratio [OR] = 0.18; 95% CI = 0.08-0.39; P < .0001) and analgesic consumption (SMD = -2.78; 95% CI = -5.05 to -0.51; P = .02), but unraveled no obvious impact on the incidence of nausea and vomiting (OR = 0.55; 95% CI = 0.24-1.27; P = .16).

CONCLUSIONS

Pregabalin supplementation was effective to improve pain relief after septorhinoplasty.

Pregabalin supplementation for the pain relief of septorhinoplasty: a meta-analysis study

BACKGROUND

Pregabalin supplementation may have some potential in improving pain relief in patients with septorhinoplasty, and this meta-analysis aims to explore the impact of pregabalin supplementation on pain control for septorhinoplasty.

METHODS

PubMed, EMbase, Web of science, EBSCO and Cochrane library databases were systematically searched, and we included randomized controlled trials (RCTs) assessing the effect of pregabalin supplementation on pain control for septorhinoplasty.

RESULTS

Six RCTs were finally included in the meta-analysis. Overall, when compared with control intervention for septorhinoplasty, pregabalin intervention showed significantly reduced pain scores at 1 h (SMD - 1.05; 95% CI - 1.85 to - 0.24; P = 0.01), 2 h (SMD - 1.01; 95% CI - 1.83 to - 0.20; P = 0.02), 6 h (SMD - 1.00; 95% CI - 1.47 to - 0.54; P < 0.0001) and 12 h (SMD - 0.69; 95% CI - 1.35 to - 0.02; P = 0.04), as well as rescue analgesics (OR 0.17; 95% CI 0.07 to 0.44; P = 0.0002), but had no notable influence on nausea and vomiting (OR 0.67; 95% CI 0.30 to 1.46; P = 0.31), or drowsiness (OR 1.22; 95% CI 0.64 to 2.35; P = 0.54).

CONCLUSIONS

Pregabalin supplementation benefits to pain control after septorhinoplasty.

Development of Physiologically Based Pharmacokinetic Model for Pregabalin to Predict the Pharmacokinetics in Pediatric Patients with Renal Impairment and Adjust Dosage Regimens: PBPK Model of Pregabalin in Pediatric Patients with Renal Impairment

Pregabalin (PGB) is widely used clinically; however, its pharmacokinetics (PK) has not been studied in pediatric patients with renal impairment (RI). To design optimized PGB regimens for pediatric patients with varying degrees of RI and predict exposure to PGB, physiologically based pharmacokinetic (PBPK) models of PGB were developed and verified, and its disposition was simulated in the healthy population and adults with RI. The simulated results from the PBPK models after single-dose and multi-dose administrations of PGB were consistent with the corresponding observed data based on the fold error values of less than 2. The area under curve ratios were 1.23 ± 0.06, 2.02 ± 0.10, 3.86 ± 0.21, and 9.92 ± 0.79 in pediatric patients with mild, moderate, severe, and end-stage RI, respectively. Based on the predictions for pediatric patients with moderate, severe, and end-stage RI, the maximum dose should not exceed 7, 3.5, and 1.4 mg/kg/day, respectively, among those weighing < 30 kg, and it should not exceed 5, 2.5, and 1 mg/kg/day, respectively, among those weighing > 30 kg. In conclusion, the developed PBPK model is a valuable tool for predicting PGB dosage for pediatric patients with RI.

No Opioids after Septorhinoplasty: A Multimodal Analgesic Protocol

Supplemental Digital Content is available in the text.

Background:

From a public health perspective, nasal surgery accounts for many unused opioids. Patients undergoing septorhinoplasty require few opioids, and efforts to eliminate this need may benefit both patients and the public.

Methods:

A multimodal analgesic protocol consisting of 15 components encompassing all phases of care was implemented for 42 patients.

Results:

Median age and BMI were 34 years and 23, respectively. Most were women (79%), White (79%), primary surgeries (62%), and self-pay (52%). Comorbid conditions were present in 74% of the patients, with anxiety (33%) and depression (21%) being the most common. Septoplasties (67%) and osteotomies (45%) were common. The median operative time was 70 minutes. No patients required opioids in recovery, and median time in recovery was 63 minutes. Ten (24%) patients required an opioid prescription after discharge. In those patients, median time to requirement was 27 hours (range 3–81), and median total requirement was 20 mg morphine equivalents (range 7.5–85). Protocol compliance inversely correlated to opioid use (P = 0.007). Compliance with local and regional anesthetic (20% versus 63%, P = 0.030) as well as ketorolac (70% versus 100%, P = 0.011) was lower in patients who required opioids. Patients who required opioids were less likely to be administered a beta blocker (0% versus 34%, P = 0.041). Pain scores were higher in opioid users on postoperative days 1–5 (P < 0.05). No complications occurred in those requiring opioids, and satisfaction rates were equivalent between groups.

Conclusion:

This protocol allowed us to safely omit opioid prescriptions in 76% of patients following septorhinoplasty, without adverse effects on outcomes or patient satisfaction.

Effects of Adding a Combined Infraorbital and Infratrochlear Nerve Block to General Anaesthesia in Septorhinoplasty

Purpose

In this study, we evaluated the hypothesis that preoperative bilateral infraoptic nerve (ION) and infratrochlear nerve (ITN) blocks under general anesthesia with sevoflurane and remifentanil reduced the incidence of emergence agitation (EA), pain scores, and the analgesic consumption after the septorhinoplasty.

Patients and Methods

Our study was conducted as a prospective randomized, double-sided blind study. Fifty-two patients whose septorhinoplasty operation was planned under general anesthesia were included in the study. Patients were randomly distributed to either the ION and ITN blocks were performed. Group 1: Bilateral ION and ITN blocks were performed; Group 2: ION and ITN blocks were not performed. Duration of the surgery and anesthesia, Riker Sedation-Agitation Scale (RSAS) score, EA presence, duration of postoperative analgesia, numerical rating scale (NRS) scores, and cumulative dexketoprofen consumption were recorded.

Results

The RSAS score, NRS score and cumulative dexketoprofen consumption of the patients in Group 1 were statistically significantly lower than the patients in Group 2 (p<0.05). It was also found that patients in Group 1 (n: 8/26) had less EA compared to patients in Group 2 (n: 16/26) and this difference was statistically significant (p: 0.026). Postoperative analgesia duration of patients in Group 1 was found to be statistically significantly higher than patients in Group 2 (p: <0.001). In addition, the number of patients given postoperative dexketoprofen in Group 1 (n: 8/26) was found to be statistically significantly lower than patients in Group 2 (n: 25/26). (p: <0.001).

Conclusion

Bilateral ION and ITN blocks in septorhinoplasty operation is an effective, reliable and simple technique in the treatment of postoperative pain.

Comparing the prophylactic effects of oral gabapentin, pregabalin, and celecoxib on postoperative pain management in orthopedic surgery of the lower extremity: A double-blind randomized controlled trial

Background:

Lower extremity pain after orthopedic surgery is so frequent that has led to many treatment modalities. This study aims to compare the prophylactic effects of oral gabapentin, pregabalin, and celecoxib on reducing postsurgical pain of the lower extremity orthopedic surgery.

Materials and Methods:

In a double-blind randomized controlled trial, 120 patients were randomly divided into four groups using block design randomization. 1 h before spinal anesthesia, the studied groups received 300 mg oral gabapentin; 75 mg oral pregabalin; 200 mg oral celecoxib; and starch as placebo. The severity of postoperative pain (using visual analog scale), mean arterial pressure, heart rate, opioid consumption dose, and drug side effects were recorded for six times (each 60 min up to two times and then every 6 h for the next four times). Chi-square, one-way analysis of variance (ANOVA), and ANOVA repeated measure tests were used for statistical analysis.

Results:

Significant reduction of pain severity was observed only at the first time measurement between pregabalin and placebo groups (P: 0.014). Patients in the pregabalin group required lower dose of opioid compared to placebo group during admission in surgical ward. There were no significant differences concerning pain reduction, opioid administration, and side effects between pregabalin, gabapentin, and celecoxib groups.

Conclusion:

Taking 75 mg oral pregabalin before lower extremity orthopedic surgery can attenuate postoperative pain, especially during the 1^st h postoperation as well as less opioid consumption and much more patients' satisfaction.
