BACKGROUND: Fentanyl-induced cough (FIC) has a reported incidence of 13–65% on induction of anesthesia. Incentive spirometry (IS) creates forceful inspiration, while stretching pulmonary receptors. We postulated that spirometry just before the fentanyl (F) bolus would decrease the incidence and severity of FIC. METHODS: This study enrolled 200 patients aged 18–60 years and with American Society of Anesthesiologists status I or II. The patients were allocated to two groups of 100 patients each depending on whether they received preoperative incentive spirometry before fentanyl administration. Patients in the F+IS group performed incentive spirometry 10 times just before an intravenous bolus of 3 µg/kg fentanyl in the operating room. The onset time and number of coughs after fentanyl injection were recorded as primary outcomes. Any significant changes in blood pressure, heart rate, or adverse effects of the drug were recorded as secondary outcomes. RESULTS: Patients in the F+IS group had a significantly lower incidence of FIC than in the F group (6% vs. 26%) (P < 0.05). The severity of cough in the F+IS group was also significantly lower than that in group F (mild, 5 vs. 17; moderate 1 vs. 7; severe, 0 vs. 2) (P < 0.05). The median onset time was comparable in both groups (9 s [range: 6–12 s] in both groups). CONCLUSIONS: Preoperative incentive spirometry significantly reduces the incidence and severity of FIC when performed just before fentanyl administration.

Background: ABO-incompatible (ABOi) kidney transplantation poses significant challenges in achieving successful outcomes. This study aimed to investigate the impact of various interventions and techniques on improving the success rates of ABOi kidney transplantation. Methods: We conducted a retrospective observational analysis of patients who underwent ABOi kidney transplantation from November 2012 to March 2023. The study included a total of 105 patients. We collected and analyzed data on patient demographics, preoperative assessments, surgical details, and postoperative outcomes. Results: The mean ages of the donors and recipients were 50.52±10.32 and 36.63±11.61 years, respectively. The majority of recipients were male (81.9%), while most donors were female (89.5%). The most common blood group among recipients was O (69.5%), and among donors, it was B (46.7%). The median durations of chronic kidney disease and dialysis were 12 months (interquartile range [IQR], 7–28 months) and 6 months (IQR, 2–12 months), respectively. Baseline antibody titers (anti-A and anti-B) ranged from 64.0 to 256.0, while on the day of surgery, they were ≤8. Perioperative complications in-cluded hypotension (10.5%), acute tubular necrosis (5.7%), delayed graft function (3.8%), and reexploration (3.8%) due to hematoma. Conclusions ABOi kidney transplantation is a viable option for recipients lacking available donors with an ABO-compatible match. Perioperative concerns, including hypoalbuminemia, heightened risk of infections, coagulopathies, aseptic precautions, and immunological surveillance, must be carefully addressed.

Background: When applying lung-protective ventilation, fluid responsiveness cannot be predicted by pulse pressure variation (PPV) or stroke volume variation (SVV). Functional hemodynamic testing may help address this limitation. This study examined whether changes in dynamic indices such as PPV and SVV, induced by tidal volume challenge (TVC), can reliably predict fluid responsiveness in patients undergoing renal transplantation who receive lung-protective ventilation. Methods: This nonrandomized interventional study included renal transplant recipients with end-stage renal disease. Patients received ventilation with a 6 mL/kg tidal volume (TV), and the FloTrac system was attached for continuous hemodynamic monitoring. Participants were classified as responders or nonresponders based on whether fluid challenge increased the stroke volume index by more than 10%. Results: The analysis included 36 patients, of whom 19 (52.8%) were responders and 17 (47.2%) were nonresponders. Among responders, the mean ∆PPV 6-8 (calculated as PPV at a TV of 8 mL/kg predicted body weight [PBW] minus that at 6 mL/kg PBW) was 3.32±0.75 and ∆SVV 6-8 was 2.58±0.77, compared to 0.82±0.53 and 0.70±0.92 for nonresponders, respectively. ∆PPV 6-8 exhibited an area under the curve (AUC) of 0.97 95% confidence interval [CI], 0.93–1.00; P≤0.001), with an optimal cutoff value of 1.5, sensitivity of 94.7%, and specificity of 94.1%. ∆SVV 6-8 displayed an AUC of 0.93 (95% CI, 0.84–1.00; P≤0.001) at the same cutoff value of 1.5, with a sensitivity of 94.7% and a specificity of 76.5%. Conclusions TVC-induced changes in PPV and SVV are predictive of fluid responsiveness in renal transplant recipients who receive intraoperative lung-protective ventilation.

Background/Aims: Exclusive enteral nutrition (EEN), an established modality for pediatric Crohn’s disease (CD) is seldomly utilized in adults. The present study reports the outcome of EEN in adult CD patients at a tertiary care hospital in India. Methods: This was a retrospective analysis of CD patients who received EEN as a sole modality/adjunct to other treatment. The primary and secondary outcomes changed in Crohn’s Disease Activity Index (CDAI), and clinical response (decline in CDAI > 70), respectively, at 4 and 8 weeks. Subgroup analysis evaluated response across different phenotypes, EEN formulations and prior treatment. Linear mixed effect model was created to assess the predictors of EEN response. Results: Thirty-one CD patients received EEN over median duration of 4 weeks (range, 2–6 weeks). CDAI showed a significant improvement post EEN at 4 (baseline 290 [260–320] vs. 240 [180–280], P= 0.001) and 8 weeks (baseline 290 [260–320] vs. 186 [160–240], P= 0.001), respectively. The cumulative clinical response rates at 4 and 8 weeks were 37.3% and 80.4% respectively. The clinical response rates at 8 weeks across B1 (n = 4), B2 (n = 18) and B3 (n = 9) phenotypes were 50%, 78.8% and 100% respectively (log-rank test, P= 0.093). The response rates at 8 weeks with polymeric (n = 8) and semi-elemental diet (n = 23) were 75% and 82.6%% respectively (log-rank test, P= 0.49). Baseline CDAI (odds ratio, 1.008; 95% confidence interval, 1.002–1.017; P= 0.046) predicted response to EEN. Conclusions EEN was effective in inducing clinical response across different phenotypes of CD. Baseline disease activity remained the most important predictor of clinical response to EEN.
