Motivational Interviewing improves postoperative nutrition goals within the Enhanced Recovery after Surgery (ERAS®) pathway in elective bowel surgery - A randomized clinical pilot trial.

BACKGROUND & AIMS: Exploration whether Motivational Interviewing (MI) could be learned and implemented with ease within a surgical in-hospital setting and whether participation in the intervention led to significantly higher compliance with ERAS®-recommended protein intake goals. The individual healing process of many patients is delayed because they fail to cover their calorie requirement, which could be counteracted by a patient-centered conversational intervention that is new in perioperative practice. METHODS: This patient-blinded pilot-RCT included 60 patients (≥18 years) following the certified ERAS® bowel protocol for colorectal surgery between March and August 2022. Five perioperative MI interventions were conducted by two health employees certified to perform MI. Key endpoints were the number of protein shakes drunk, calories of proteins ingested and overall calorie intake. RESULTS: A total of 60 patients (34 men [56.7%]; mean [SD] age, 60.7 [13.3] years) were randomized. MI patient-group had significantly higher protein shake intake on all postoperative days except day 3. For days 0-3 MI group drank significantly more shakes overall (median 5.5 vs. 2.0; P = 0.004) and consumed more calories (median 1650.0 vs. 600.0 kcal; P = 0.004) and proteins (median 110.0 vs. 40.0 g; P = 0.005). Total calorie intake for each day by shakes and dietary intake was significantly higher in the MI-intervention group on day 2 (mean 1772.3 vs. 1358.9 kcal; P = 0.03). CONCLUSIONS: MI may contribute to improve compliance with nutritional goals in the certified ERAS® protocol by increasing protein and calorie intake. The findings suggest further investigation of MI to help patients achieve their perioperative nutrition goals in different clinical settings.

Influence of motivational interviewing on postoperative mobilization in the enhanced recovery after surgery (ERAS®) pathway in elective colorectal surgery - a randomized patient-blinded pilot study.

PURPOSE: Early mobilization is an essential component of the Enhanced Recovery after Surgery (ERAS®)-pathway. However, a large percentage of patients fail to achieve the ERAS® recommended goal (360 min out of bed from post-operative day 1/POD1). Motivational Interviewing (MI) is an evidence-based type of patient-centered consultation to promote intrinsic motivation. This study aims to evaluate if MI can improve postoperative mobilization. METHODS: This two-arm, patient-blinded pilot randomized controlled trial included ERAS®-patients undergoing elective bowel resections. Conversations were validated by MI Treatment Integrity. Two validated motion sensors (movisens) and self-assessments were used to measure mobilization (POD1-POD3: Time out of bed, time on feet and step count). RESULTS: 97 patients were screened, 60 finally included and randomized. Cumulatively across POD1-3, the intervention group (IG) was longer out of bed than the control group (CG) (median: 685 vs. 420 min; p=0.022). The IG achieved the ERAS®-goal of 360 min/day more frequently across POD1-3 (27.4% vs. 10.61%; p=0.013). Time on feet was 131.5 min/day (median per POD) in IG vs. 95.8 min/day in the CG (p=0.212), step count was 1347 in IG vs. 754 steps/day in CG (p=0.298). CONCLUSION: MI could be conducted low threshold and was well accepted by patients. MI can improve mobilization in the context of ERAS®. Despite better performance, it should be noted that only 27.4% of the IG reached the ERAS®-compliance goal of 360 min/day. The findings of this pilot study stipulate to further test the promising perioperative effects of MI within a multicenter superiority trial. REGISTRATION: This study was registered prospectively in the German Clinical Trials Register on 25.02.2022. Trial registration number is "DRKS00027863".

Perioperative systemic magnesium sulfate minimizes the incidence of atrial fibrillation after thoracotomy for lung resection: a prospective observational study.

Background: Postoperative atrial fibrillation (POAF) is the most common complication following general thoracic surgery. POAF significantly increases the risk of adverse cardiovascular events, such as thromboembolism, heart failure, and mortality. Additionally, it also leads to prolonged hospital stays and higher costs. The objective of this observational study was to examine the impact of perioperative administration of magnesium sulphate (MgSO4) on the incidence of POAF. Methods: A prospective observational study was conducted, enrolling one hundred patients undergoing thoracotomy for lung resection. We compared the incidence of atrial fibrillation (AF) before and after implementing a change in our standard anesthetic management, which involved the addition of MgSO4. MgSO4 was administered during anesthesia induction at a dose of 40 mg/kg over ten minutes, followed by a 24-hour infusion at a rate of 10 mg/kg/h. The primary outcome was the incidence of POAF within the first seven days after surgery. Results: Within the initial three days following surgery, there was no significant difference in the cumulative incidence of POAF between the MgSO4 group and the control group. However, on postoperative day 7, patients treated with MgSO4 exhibited a reduced incidence of POAF compared to the control group (4% vs. 26%; P=0.01). In the subgroup of patients not receiving pre-existing ß-blockers, the addition of MgSO4 significantly decreased the occurrence of POAF (14% vs. 80%; P<0.001). Conclusions: Prophylactic administration of MgSO4 is a potentially beneficial approach for reducing the incidence of POAF after non-cardiac surgery, particularly in patients not receiving long-term ß-blocker treatment.

Perioperative systemic magnesium sulphate to minimize acute and chronic post-thoracotomy pain: a prospective observational study.

BACKGROUND: Thoracotomy leads to acute and chronic post-thoracotomy pain (CPTP). The purpose of this study was to investigate the effect of magnesium sulphate (MgSO4) administered perioperatively on acute postoperative and CPTP syndrome. METHODS: One hundred patients were enrolled in this prospective, observational study. Analgesic medication was provided according to the World Health Organization pain relief ladder (control group). The study group received additionally MgSO4 (40 mg/kg over 10 minutes) during induction of anesthesia followed by an infusion over 24 hours (10 mg/kg/h). The presence and severity of pain were assessed before surgery, on postsurgical days 1-8, 30 and 90, respectively. The Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) was used pre- and postoperatively for documentation of neuropathic pain. The incidence and severity of CPTP were assessed by a telephone survey 30 and 90 days after surgery. RESULTS: Numerical rating scale (NRS) pain scores at rest were significantly lower in the study group receiving MgSO4 at days 1 to 8 (P<0.05). Thirty days after surgery, 2.1% of the MgSO4-patients had a LANSS score ≥12 compared to 14.3% in the control group (P=0.031). No patient had a LANSS score ≥12 in the study group compared to the control group (0% vs. 12.2%, P<0.05) 90 days following surgery. CONCLUSIONS: MgSO4 administration reduces postoperative pain at rest according to the NRS pain scores and is effective in preventing chronic neuropathic post-thoracotomy pain measured by LANSS score. Prospective-randomized trials are needed to confirm the results of the present study.

Comparing Patient Satisfaction and Intubating Conditions Using Succinylcholine or Low-Dose Rocuronium for Rigid Bronchoscopy: A Randomized Study.

INTRODUCTION: Despite its serious side effects, succinylcholine is commonly used for neuromuscular relaxation in short procedures, such as rigid bronchoscopy and tracheobronchial interventions. The application of low-dose rocuronium reversed by low-dose sugammadex might be a modern alternative. The aim of this study was to compare patient satisfaction, incidence of postoperative myalgia (POM) as well as intubating conditions of these two muscle relaxants for rigid bronchoscopy. METHODS AND MATERIALS: A single-center, prospective-randomized, blinded study of 95 patients, scheduled for rigid bronchoscopy and tracheobronchial intervention was conducted. The patients were anesthetized with propofol, remifentanil and either low-dose succinylcholine (S) (0.5 mg/kg) or low-dose rocuronium (0.25 mg/kg) with sugammadex (RS) (0.5 mg/kg). All patients were evaluated on the first and second postinterventional day for their satisfaction with the treatment (rigid bronchoscopy) using a Numeric Analog Rating Scale (NAS 0-10) and the presence and severity of POM (NAS 1-4). Intubating conditions were assessed as excellent, good, or poor on the basis of position of vocal cords and reaction to insertion of the rigid bronchoscope. RESULTS: Patients in the S group were less satisfied with the treatment than patients in RS group (72.7 vs. 93.7%, p = 0.007). The incidence of POM on the first day after intervention was significantly higher in the S group then in the RS group (56.9% vs. 4.3%, p < 0.001). Although the intubation was faster (p < 0.001) and the intubating conditions significantly superior (p < 0.003) with succinylcholine, acceptable conditions were also achieved with low-dose rocuronium in 75% of patients. The anesthetic drug costs were significantly higher in the RS group then in the S group (p < 0.001). CONCLUSION: The results suggest that low-dose rocuronium provided better patient satisfaction and less POM. But with the use of low-dose succinylcholine, the intubating conditions are more comfortable, and it is less expensive than rocuronium/sugammadex.
