Opioid abuse-deterrent strategies: role of clinicians in acute pain management

Minimizing the Risk of Opioid Misuse and Abuse in the Surgical Setting

The misuse of opioids continues to be a public health problem. Acute post-surgical pain management requires a careful balance between the benefits and risks of opioids. Opioids should be part of a multimodal treatment plan, including the use of nonopioid and nonpharmacologic treatment options. Multimodal pain management allows for individualized treatment and improved patient satisfaction while limiting the risks inherent to opioids, including diversion. Surgeons should avoid overprescribing opioids and have a plan for decreasing the use of opioids in the postsurgical time frame. With careful consideration of the risks, opioids can be prescribed to treat acute postsurgical pain effectively. [Orthopedics. 2021;44(6):353-359.].

Feasibility of implementing a virtual reality program as an adjuvant tool for peri-operative pain control; Results of a randomized controlled trial in minimally invasive foregut surgery

BACKGROUND

Post-operative pain control and narcotic over-utilization are challenging issues for surgeons in all fields. While virtual reality (VR) has been increasingly applied in various fields, its feasibility and efficacy in the peri-operative period has not been evaluated. The aim of this study was to examine the experience of an integrated VR protocol in the perioperative setting.

METHODS

Patients undergoing minimally invasive foregut surgery at a single institution were randomized to receive a series of VR meditation/mindfulness sessions (VR) or to standard care after surgery (non-VR). Post-operative pain levels, narcotic utilization and patient satisfaction were tracked.

RESULTS

Fifty-two patients were enrolled with 26 in each arm. Post-operative pain scores, total narcotic utilization, and overall satisfaction scores were not significantly different between the two groups. For patients in the VR arm, sessions were able to be incorporated into the perioperative routine with little disruption. Most (73.9 %) were able complete all six VR sessions and reported low pain, anxiety, and nausea scores while using the device. A high proportion responded that they would use VR again (76.2 %) or would like a VR program designed for pain (62.0 %). There were no complications from device usage.

CONCLUSION

VR is a safe and simple intervention that is associated with high patient satisfaction and is feasible to implement in the perioperative setting. While the current study is underpowered to detect difference in narcotic utilization, this device holds promise as an adjuvant tool in multimodal pain and anxiety control in the peri-operative period.

Effects of different analgesia regimens on early post-operative cognitive dysfunction in elderly patients undergoing radical resection of cervical carcinoma

This study was designed to compare the effects of epidural and intravenous analgesia on early post-operative cognitive dysfunction (POCD) in elderly patients undergoing radical resection of cervical cancer. For this purpose, 74 patients aged 60-78 years [body mass index (BMI), 18-25 kg/m²; American Society of Anesthesiologists (ASA) classification score of I-III) undergoing radical resection of cervical cancer were divided into the epidural group (group E) and parenteral group (group P) groups (37 patients in each group). All patients underwent their surgical procedures under epidural anesthesia and intravenously-delivered general anesthesia. Patient-controlled analgesia (PCA) was supplied for 72 h after the surgery. Epidural analgesia was provided for the patients in group E and intravenous analgesia was provide for those in group P. General patient information was recorded and peripheral blood neutrophil counts, C-reactive protein (CRP) levels and interleukin (IL)-6 concentrations were measured immediately prior to the surgery (T₀), and at 24, 48 and 72 h after the procedure (T₁, T₂ and T₃, respectively). Visual analog scale (VAS) scores were also recorded at T₁, T₂ and T₃, and the mini-mental state evaluation (MMSE) scores at T₀, T₁, T₂, and T₃ were calculated. Patients were diagnosed as having POCD according to their MMSE score differences between the peri-operative and post-operative values. The results revealed that the levels of CRP and IL-6 significantly increased in both groups after the surgery (T_1-3). However, the CRP and IL-6 levels in group E were significantly lower than those in group P at all time points examined (P<0.05). The VAS scores in group E at T₁, T₂ and T₃ were significantly lower than those in group P (P<0.05). Finally, the incidence of POCD in group E was significantly lower than that in group P (P<0.05). On the whole, the post-operative epidural analgesia reduced the systemic inflammatory response, the perceived pain, and the incidence of POCD in patients undergoing radical resection of cervical cancer, when compared with the effects of intravenous analgesia.

Depression and pain: primary data and meta-analysis among 237 952 people across 47 low- and middle-income countries

BACKGROUND

Depression and pain are leading causes of global disability. However, there is a paucity of multinational population data assessing the association between depression and pain, particularly among low- and middle-income countries (LMICs) where both are common. Therefore, we investigated this association across 47 LMICs.

METHODS

Community-based data on 273 952 individuals from 47 LMICs were analysed. Multivariable logistic and linear regression analyses were performed to assess the association between the International Classification of Diseases, 10th Revision depression/depression subtypes (over the past 12 months) and pain in the previous 30 days based on self-reported data. Country-wide meta-analysis adjusting for age and sex was also conducted.

RESULTS

The prevalence of severe pain was 8.0, 28.2, 20.2, and 34.0% for no depression, subsyndromal depression, brief depressive episode, and depressive episode, respectively. Logistic regression adjusted for socio-demographic variables, anxiety and chronic medical conditions (arthritis, diabetes, angina, asthma) demonstrated that compared with no depression, subsyndromal depression, brief depressive episode, and depressive episode were associated with a 2.16 [95% confidence interval (CI) 1.83-2.55], 1.45 (95% CI 1.22-1.73), and 2.11 (95% CI 1.87-2.39) increase in odds of severe pain, respectively. Similar results were obtained when a continuous pain scale was used as the outcome. Depression was significantly associated with severe pain in 44/47 countries with a pooled odds ratio of 3.93 (95% CI 3.54-4.37).

CONCLUSION

Depression and severe pain are highly comorbid across LMICs, independent of anxiety and chronic medical conditions. Whether depression treatment or pain management in patients with comorbid pain and depression leads to better clinical outcome is an area for future research.
