Acute pain service: Round the clock vigilance

Efficacy of ultrasound guided quadratus lumborum block as postoperative analgesia in renal transplantation recipients: A randomised double blind clinical study

Background and Aims

Postoperative pain following renal transplantation is moderate to severe. Quadratus lumborum block (QLB) is a new block that can provide effective analgesia following abdominal and retroperitoneal surgeries. This study aimed to evaluate the analgesic efficacy of QLB for postoperative analgesia in patients undergoing renal transplantation.

Methods

Patients were randomised into two groups of 30 each. In group A (block group), 20 mL of 0.25% bupivacaine and group B (placebo group), 20 mLof normal saline were injected. In the postoperative room, an intravenous patient controlled analgesia (IVPCA) pump with fentanyl was started in both the group. The postoperatively recorded parameters were numerical rating scale (NRS) pain score at rest and on movement and coughing, total fentanyl consumption, sedation score, postoperative nausea vomiting, limb weakness, paralytic ileus, and any other block-related complication. Data were analysed using SPSS software version 22.0. Categorical data were analysed using the Chi-square method. Student t test or Mann-Whitney U test was applied for the continuous data. Numerical data with normal distribution were displayed as mean (standard deviation), abnormal distribution was displayed in the median (interquartile range) values, and as a percentage for categorical variables.

Results

Fentanyl consumption, numerical rating score, and sedation score were significantly less in group A when compared to group B at 1, 4, 8, 12, and 24 h (P < 0.001).

Conclusion

Type-1 QLB significantly reduces fentanyl consumption and NRS pain score at 1,4,8,12, and 24 h in the postoperative period in renal transplant recipients.

Does an acute pain service improve the perception of postoperative pain management in patients undergoing lower limb surgery? A prospective controlled non-randomized study

Background and Aim:

An acute pain service (APS) has been running in our institute since April 2013 and is managed by the Department of Anesthesia and Intensive Care. However, it is not clear to what extent the patients feel benefited from the APS. The aim of the study was to compare the perception of postoperative pain management in patients receiving care under APS with those receiving routine postoperative pain relief following lower limb surgery.

Material and Methods:

This was a prospective, hospital-based, controlled non-randomized study. American Society of Anesthesiologists (ASA) grades I–III patients with age 18–75 years undergoing lower limb orthopedic surgery were prospectively recruited into APS (index group) or routine postoperative care (control group) (n = 55 each). Postoperatively, American Pain Society Patient Outcome Questionnaire-Revised (APS-POQ-R) and Short Form (SF-12) were used to evaluate the outcome of postoperative pain management at 24 h and health-related quality of life after 4 weeks respectively.

Results:

Both groups were comparable in terms of demographic data. Patients in the index group had statistically significant better perception of care than the control group. Index group scored significantly higher than control group on median patient satisfaction score (9; interquartile range [IQR] [7–10] vs. 5 [3–6]; P < 0.001). In index group, there was significant reduction of worst pain in first 24 h along with decreased frequency of severe pain.

Conclusion:

Implementation of acute pain service plays an important role in improving the quality of postoperative pain relief, perception of care, and patient satisfaction.

Acute postoperative pain experiences and satisfaction with its management among patients with elective surgery: An observational study

BACKGROUND AND AIM

There is a paucity of regional data on acute postoperative pain. The present study was conducted with an aim to assess the acute postoperative pain experiences, its interference with ADLs, emotions, sleep, IPR and satisfaction with pain management among patients who had undergone elective surgeries.

METHODS

In this observational study, 200 postoperative adult patients; who had undergone elective surgery were interviewed using American Pain Society's Patient Outcome and Satisfaction Survey Questionnaire. Pain perception and interference of pain with ADLs, emotions, sleep, and IPR was measured on 0-10 numerical scale and satisfaction on 6 point Likert scale, i.e., very satisfied to very dissatisfied.

RESULTS

There was high incidence (82.5%) of acute postoperative pain experience and mean score for worst episodes of pain was significantly high, i.e., 7.6 ± 1.5, which had significant interference with ADLs (5.6 ± 2.1), sleep (3.6 ± 1.7), and emotions (3.6 ± 1.6). Majority of patients reported that pain was assessed only once (17%) or twice (48.5%) in each shift. Despite of poor pain control, a large number of patients were satisfied with overall pain treatment (69%), and response of physicians (81%) and nurses (62%) for their pain complaints. Acute pain score was directly associated with the duration of postoperative hospital stay (P = 0.001).

CONCLUSION

Acute postoperative pain was inadequately assessed and undertreated but still a large number of participants were satisfied with acute postoperative pain management probably because patients expects that pain is inevitable after surgery. Postoperative pain had significant interference with ADLs, emotions and sleep of patients, which may affect postoperative comfort and recovery.
