Prevalence and Risk Factors for Acute Postoperative Pain After Elective Orthopedic and General Surgery at a Tertiary Referral Hospital in Tanzania

The analgesic effectiveness of auriculotherapy for acute postoperative pain: A systematic review and meta-analysis

BACKGROUND

Postoperative pain is a significant yet inadequately managed complication following surgery, and auriculotherapy to alleviate acute postoperative pain (APP) and reduce the use of opioids remains controversial.

METHODS

We searched the MEDLINE, Web of Science, Embase, Cochrane Library, CINAHL Complete, and ClinicalTrials.gov from inception to January 23, 2024 for all randomized controlled trials (RCTs) of auriculotherapy in the treatment of APP. The extracted data underwent risk of bias assessment, meta-analysis, subgroup analyses, sensitivity analysis, meta-regression analysis, and evidence rating.

RESULTS

A total of 24 studies involving 2131 patients were included in the meta-analysis. Low-quality evidence indicated that auriculotherapy was effective in reducing pain intensity at 24 [MD(95 %CI)=-0.64(-1.09, -0.19), I2=77 %, P＜0.01], 48 [MD(95 %CI)=-0.49(-0.97, 0.00), I2=71 %, P=0.05], and 72 [MD(95 %CI)=-0.80(-1.32, -0.28), I2=52 %, P＜0.01] hours after surgery, while moderate-quality evidence showed a decrease in total opioid consumption [MD(95 %CI)=-24.41 OME (-38.28, -10.54), I2=95 %, P＜0.01]. However, no significant effects were observed in reducing postoperative nausea or vomiting [RR(95 %CI)=0.61(0.32, 1.16), I2=71 %, P=0.13; RR(95 %CI)=0.32(0.09, 1.18), I2=71 %, P=0.09; RR (95 %CI)=0.34(0.11, 1.06), I2=28 %, P=0.06; for postoperative nausea and vomiting (PONV), postoperative nausea or postoperative vomiting respectively], with evidence ranging from moderate to very low. Additionally, two RCTs found that auriculotherapy could delay the time to the first request for analgesia.

CONCLUSIONS

The summary estimates indicate that auriculotherapy may be beneficial in reducing APP and opioid consumption in specific surgeries based on low-to-moderate quality evidence. However, high-quality RCTs are still further studied in different surgical populations.

Preexisting chronic pain is not associated with moderate-to-severe acute pain after laparoscopic cholecystectomy: a prospective cohort study

Introduction

We aimed to evaluate the relationship between preexisting chronic pain and acute postoperative pain after laparoscopic cholecystectomy (LC) and to identify predictors of acute postsurgery pain.

Methods

In this prospective cohort study, patients undergoing LC with general anesthesia were enrolled. The primary outcome was the incidence of moderate-to-severe pain during movement in the first 24 hours after surgery. Logistic regression analysed the association of perioperative risk factors with acute postoperative pain. Model performance was assessed using receiver operating characteristic curves (ROC), calibration belt plots, and 10-fold cross-validation.

Results

Of the 193 patients analysed, 49.74% experienced moderate-severe acute pain. Univariable analysis indicated that preoperative chronic pain increased the likelihood of acute postoperative pain (odds ratio [OR], 2.53; 95% confidence interval [CI], 1.40-4.55). Risk factors identified in the multivariable analysis were higher preoperative pain intensity (OR, 1.28; 95% CI, 1-1.65), sleep disturbances (OR, 1.42; 95% CI, 1.24-1.61), intraoperative fentanyl supplementation (OR, 3.68; 95% CI, 1.48-9.12), incision extension for gallbladder retrieval (OR, 7.27; 95% CI, 1.58-33.39), and abdominal drain placement (OR, 6.09; 95% CI, 1.08-34.34). Dexamethasone use was associated with reduced pain (OR, 0.05; 95% CI, 0.004-0.74). The model demonstrated strong discrimination (ROC = 0.909) and good calibration (test statistic = 0.02; P = 0.89). Cross-validation showed slightly lower accuracy (ROC = 0.896).

Conclusions

Preexisting chronic pain was not associated with acute postoperative pain following laparoscopic cholecystectomy. Significant predictors for acute pain included higher preoperative pain intensity, sleep disturbances, intraoperative fentanyl, incision extension, and abdominal drain placement, while dexamethasone use was associated with reduced pain.

Continuous Catheter Versus Single-Shot Interscalene Block in Shoulder Surgery: A Review and Recommendations for Postoperative Pain Management

Shoulder arthroscopic and arthroplastic surgeries are associated with significant postoperative pain, which can delay recovery and increase opioid consumption. Interscalene blocks (ISBs) are a commonly used method to manage this pain, either as single-shot injections or continuous catheter infusions (CISBs). This review synthesizes findings from studies conducted in the past five years, comparing the efficacy, complications, and outcomes of single-shot ISBs versus CISBs for postoperative pain management in shoulder surgeries. Current literature highlights key differences: single-shot ISBs provide significant immediate postoperative pain relief, whereas CISBs offer prolonged analgesia beyond 48 hours, reduced opioid consumption, and enhanced recovery outcomes. However, CISBs carry a higher risk of complications and procedural complexity compared to single-shot ISBs. Both single-shot ISBs and CISBs present effective options for postoperative pain control in shoulder surgery patients. Single-shot ISBs may be preferable for patients seeking immediate pain relief with fewer complications, while CISBs are beneficial for those requiring prolonged analgesia. The choice of technique should be individualized based on the patient's needs, expected recovery, and potential risk factors.

Prevalence and associated factors of acute postoperative pain in adult surgical patients: A prospective study

Background

Pain, as defined by the International Association for the Study of Pain, is an unpleasant sensory and emotional experience associated with, or resembling, that is associated with actual or potential tissue damage. In Ethiopia, where healthcare facilities and offerings are expanding to handle countless patients requiring surgical intervention, managing acute postoperative pain is a serious concern.

Objectives

To assess the prevalence of acute postoperative pain and associated factors after elective surgery among adult patients at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia, 2023.

Methodology

This is an institution-based cross-sectional study. A structured data collection format was used to collect data from 219 participants. Bivariable and multivariable logistic regression analyses described the association between independent and dependent variables.

Results

Of 219 patients, 180 (82.2 %) had acute postoperative pain. The prevalence of moderate to severe pain was 34.24 %. Preoperative anxiety, the use of intraoperative analgesics, and duration of surgery were the main factors associated with the prevalence of acute postoperative pain.

Conclusion

Our study revealed that the overall prevalence of postoperative pain was relatively low in the study area. This suggests that the attention given to postoperative pain recognition and management is better than that in other areas. However, the finding of a significant gap in managing postoperative pain underscores the need for further improvements in pain management practices. This should motivate us to commit to change, particularly in the identified areas of concern, such as preoperative anxiety, use of intraoperative analgesics, and duration of surgery.

Healthcare providers' pain management practice and its associated factors in Ethiopia: A systematic review and meta- analysis

INTRODUCTION

Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Under -treatment of pain continues to be a major health care problem in Ethiopia. Although it has this problem, it receives limited research attention. This systematic review and meta-analysis will provide valuable insights of prevalence and its factors of healthcare providers' pain management practice in Ethiopia.

METHODS

This systematic review and meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Universal online databases such as PubMed, Cochrane, Google, Google Scholar, SCOPUS, Web of Science and Global Health were used to search for articles. Microsoft Excel for data extraction and STATA17 for data analysis were used. DerSimonian and Laird random-effects model was used to pool the odds ratios across studies and compute the overall pooled prevalence and its predictors. Egger's test with funnel plot symmetry and Cochrane's Q test was used to assess publication bias and heterogeneity respectively.

RESULTS

The overall pooled prevalence of health care providers' pain management practice was 39.6% (95% CI: 34.8, 44.5); I2 = 97.0%; P<0.001). Availability of pain management protocol (AOR = 5.1, 95%CI: 3.6, 6.7), Accessibility of analgesia (AOR = 4.5, 95%CI: 1.96, 7.0), higher educational level (AOR = 3.3, 95%CI: 2.5, 4.1), being female (AOR = 1.2, 95% CI: 1.6, 3.1), took training (AOR = 2.7, 95% CI: 1.8, 3.6), decreased work load (AOR = 4.9, 95% CI: -1.9, 11.7), increased work experience (AOR = 3.9, 95% CI: 2.9, 5.1), Being midwifery profession (AOR = 2.5,95% CI: 1.6, 3.4), having good attitude (AOR = 3.9,95%CI: 2.5, 5.4) and being knowledgeable (AOR = 4.2, 95%CI: 2.8, 5.6) of health care providers towards pain management practice were significantly associated in Ethiopia.

CONCLUSION

The overall prevalence of pain management practice among healthcare providers in Ethiopia is low compared with a national target of pain free hospital initiatives in Ethiopia. It needs a call to build health care providers' ongoing education, training, professional development and manageable workload.

The Effect of Aromatherapy with Citrus aurantium Aroma on Pain after Orthopedic Surgery: A Randomized Clinical Trial

Introduction

Postoperative pain is one of the most common physiological and psychological stress in patients that disrupts body function and can endanger patients' health. This study aims to determine the effect of aromatherapy with Citrus aurantium essential on pain after orthopedic surgery.

Methods

This randomized clinical trial was performed on 60 candidates for orthopedic surgery. Patients were selected through convenience sampling and divided into intervention and control groups through randomized block allocation. If the visual analogue scale (VAS) score was above 3, patients in the intervention group received aromatherapy with C. aurantium essential and the patients in the control group received a placebo (almond oil). VAS was used to measure pain. Data analysis was performed using independent t test, paired t test, and analysis of variance with repeated measures using SPSS software version 13.

Results

Mean (SD) of pain intensity after intervention in experimental and control groups within 4, 8, and 12 hours after surgery was 7.30 (1.23) vs. 7.90 (0.99), 5.30 (0.98) versus 5.53 (0.68) and 2.53 (0.9) vs. 3.60 (0.77) respectively. The findings indicated that there was a significant difference in mean pain intensity between the experimental and control groups at 4 and 12 hours after surgery. Use of analysis of variance with repeated measures test with taking into account the interaction of time and group also showed a significant difference in mean pain intensity between the two experimental and control groups.

Conclusion

Aromatherapy with Citrus aurantium essential can be effective in reducing mild to moderate pain after orthopedic surgery. Further studies are recommended to confirm this finding.

Review of the Current Situation of Postoperative Pain and Causes of Inadequate Pain Management in Africa

Postoperative pain is one of the most prevalent complications following surgery, and more than 47% of surgical patients endure postoperative discomfort worldwide. In Africa, due to resource shortages and other issues, postoperative pain is substantially more common when compared to developed countries. Severe postoperative pain has many negative effects, including possibly death, which can burden both individuals and society as a whole. Therefore, effectively controlling postoperative pain is becoming increasingly important. To enhance the effectiveness of future pain management, a thorough analysis of the current reasons for inadequate postoperative pain management is necessary. In this article, the present situations of occurring postoperative pain, children's postoperative pain, and pain management in Africa are reviewed, based on relevant and recent literature. In particular, the reasons for inadequate postoperative pain management in Africa are detailed in this article from five perspectives: the inadequate assessment of postoperative pain, the knowledge gap among medical professionals, the patients' misconceptions, the scarcity of resources, and the lack of medications. Additionally, we offer appropriate solutions following various factors.

Incidence and Associated Factors of Postoperative Undesirable Anesthetic Outcomes Among Surgical Patients at Referral Hospitals in Amhara Region, Ethiopia: A Multi-Center Study

Background

Patients undergoing surgery frequently experience unfavorable anesthetic outcomes. They may have an impact on body systems and result in more serious postoperative morbidities. This study was conducted to determine the incidence of postoperative undesirable anesthetic outcomes among surgical patients at referral hospitals in Amhara region, Ethiopia.

Methods

A total of 412 patients, who underwent surgical procedures between August 1 and October 30 of 2022, were included in this study. The Leiden Perioperative Care Patient Satisfaction Questionnaire's (LPPSq) dimension "discomfort and needs" was used to collect data on the first postoperative day. Data entry and analysis were performed using SPSS version 20. To assess how risk factors affected the outcome variable, logistic regression analysis was utilized. In multivariable logistic regression analysis, a variable with a P-value of less than 0.05 was statistically considered as significant.

Results

The proportion of those who had "at least a little bit" of unfavorable outcomes was calculated to estimate their overall prevalence, and the prevalence of those who had "more than moderate" levels of unfavorable outcomes was determined to appreciate how severe these outcomes were. The percentages of postoperative pain, the most common undesired result, for "at least a little bit" and "more than moderate" were 87.7% and 32.3%, respectively. In this study, postoperative cold was the least prevalent (51.4%) undesirable anesthetic outcome. The remaining undesirable postoperative outcomes were reported less frequently.

Conclusion and Recommendation

Undesirable postoperative anesthetic outcomes were still common. The most frequent unfavorable result was postoperative pain. Adequate postoperative patient follow-up and quality service are paramount.

Modifiable factors associated with a consistently high acute pain trajectory after surgical treatment of traumatic fractures in Ethiopia: a multi-center prospective cohort study

BACKGROUND

In Ethiopia, little is known about postoperative pain trajectories and possible predictive factors associated with them in patients undergoing surgery following traumatic fractures.

METHODS

This multi-center prospective observational cohort study included surgical candidates for traumatic fractures (n = 218). Worst pain intensity was measured with an 11-point numeric rating scale on the first 4 postoperative days and day of hospital discharge. Growth mixture modeling was used to identify subgroups of patients based on their pain trajectories, and logistic regression models to quantify associations between pain trajectories and demographic, clinical, psychological, and life style factors.

RESULTS

Two postoperative pain trajectory subgroups were identified: rapid pain relief (48% of included individuals) and consistently high pain (52% of included individuals). Sub-analysis stratified by cause of injury demonstrated that higher preoperative pain was an independent risk factor for consistently high postoperative pain regardless of the patient's injury type: traffic accident (OR = 1.48, 95% CI 1.23-1.79), machine/tool injury or conflict (OR = 1.58, 95% CI 1.11-2.26), or fall (OR = 1.47, 95% CI 1.08-1.99). Moreover, longer surgical time was a risk factor for consistently high postoperative pain among patients who had a fall-related injury (OR = 1.02, 95% CI 1.00-1.03). In contrast, among patients with a traffic-related injury, receiving a nerve block was a protective factor (OR = 0.19, 95% CI 0.04-0.87) compared with general anesthesia.

CONCLUSION

Higher preoperative pain and longer surgical time were associated with a consistently high acute postoperative pain trajectory. Clinicians may use these potentially modifiable factors to identify patients at risk for consistently high pain during the early postoperative period.

A Bibliometric Analysis of Published Literature in Postoperative Pain in Elderly Patients in Low- and Middle-Income Countries

Postoperative pain (POP) remains a major challenge for surgeons and anesthesiologists worldwide, especially in low- and middle-income countries. Elderly patients are at higher risk for undertreatment of pain. Despite that, there is a paucity of papers addressing POP among this population in developing countries. This study aimed to provide a bibliometric analysis of the literature concerning postoperative pain in elderly patients from low- and middle-income countries. It was performed an extensive search of papers on this subject through the Web of Science and Scopus database using a series of uniterms and, including publications from 2001 to 2021. Publication quality was assessed by using total citation frequency, average citations per item and other citation indexes. Citation indexes were low, with the highest reaching 15 citations. In conclusion, few studies of postoperative pain in the elderly in countries with medium and low income, indicating a need that has not yet been met for this population and in these areas of the world. The published studies were not specifically aimed at the elderly, had limited impact, low international visibility. They were not epidemiological studies and are not robust, weakening knowledge and decision-making towards policies directed at this vulnerable population.
