The Analgesic Effects of the Addition of Intravenous Ibuprofen to a Multimodal Analgesia Regimen for Pain Management After Pediatric Cardiac Surgery: A Randomized Controlled Study.

OBJECTIVE: Intravenous ibuprofen is used to control fever and pain. This study aimed to assess the analgesic effects of the addition of intravenous ibuprofen to a multimodal analgesia regimen for pain management after pediatric cardiac surgery. DESIGN: A randomized, controlled, double-blinded, superiority study. SETTING: University hospital. PARTICIPANTS: Seventy-eight pediatric patients who underwent open cardiac surgery using midline sternotomy incision were screened for eligibility; 10 patients were excluded, leaving 68 patients (34 patients in the ibuprofen group and 34 patients in the control group) for final data analysis. INTERVENTIONS: Patients were randomly allocated to either the ibuprofen group, in which the patient received intravenous ibuprofen infusion of 10 mg/kg/6 hours for 24 hours, or the control group, in which the patient received a placebo 0.9% saline. MEASUREMENTS AND MAIN RESULTS: The primary endpoint was the 24-hour postoperative fentanyl consumption, and the secondary endpoints were postoperative modified objective pain score and the incidence of ibuprofen-related side effects (eg, vomiting, epigastric pain, bleeding, and renal dysfunction). The mean total fentanyl consumption (µg/kg) during the first postoperative 24 hours after extubation was significantly lower (p<0.001) in the ibuprofen group (3.5 ± 1.3) than the control group (5.1 ± 1.4). The median postoperative modified objective pain score was significantly lower (p < 0.05) in the ibuprofen group than the control group at 0 hours, 2 hours, 12 hours, 16 hours, 20 hours, and 24 hours postoperatively. Ibuprofen did not cause significant increases in the incidences of bleeding, epigastric pain, and vomiting. Postoperative renal dysfunction was not reported in any patient. CONCLUSIONS: The addition of intravenous ibuprofen to a multimodal analgesia regimen for pain management after pediatric cardiac surgery improved postoperative analgesia in terms of reduction of opioid consumption and pain scores.

The direct comparison of inhaled versus intravenous levosimendan in children with pulmonary hypertension undergoing on-cardiopulmonary bypass cardiac surgery: A randomized, controlled, non-inferiority study.

STUDY OBJECTIVE: Pulmonary arterial hypertension is commonly seen in children with left to right intracardiac shunts and affects the outcomes of cardiac surgery. Our study aimed to compare the efficacy of inhaled levosimendan (LS) versus intravenous LS in reducing elevated pulmonary artery pressure (PAP) in children scheduled for cardiac surgery. DESIGN: Non-inferiority, prospective, randomized, blinded, controlled study. SETTING: Operative room and intensive care unit (ICU), institutional children's hospital of Mansoura Faculty of Medicine, Egypt. PATIENTS: 50 patients of either sex, aged 1 to 5 years undergoing surgical repair of intracardiac left to right shunt complicated by pulmonary hypertension were recruited for the study. INTERVENTIONS: In the intravenous LS group, patients received intravenous infusion of LS a rate of 0.1 µg/kg/min and in the inhaled LS group, LS (36 µg/kg/6 h) was delivered by nebulization. MEASUREMENTS: The primary endpoint was systolic PAP, while the secondary endpoints were the heart rate, mean arterial blood pressure, dose of norepinephrine, time to extubation and ICU length of stay. MAIN RESULTS: Both intravenous and inhaled routes of LS similarly reduced the high systolic PAP over all time points of measurement and intravenous LS was associated with higher heart rate, lower arterial pressure and the need for a higher dose of norepinephrine than the inhaled LS. CONCLUSION: Inhalation of LS is non-inferior to intravenous LS in reducing high PAP in children who underwent on-pump cardiac surgery and it is associated with less tachycardia and hypotension with reduced need for vasoactive drugs.

Central Venous Access in Neonates: Comparison of Ultrasound-Guided Percutaneous Access and Minimal Surgical Open Methods.

Background: In neonates, percutaneous central venous catheter (CVC) insertion is often a challenging technique. Recent reports have reported the efficacy of ultrasound (US) guidance when performing such an intervention. We conducted this study to compare US-guided and minimal surgical CVC insertion regarding time and ease of insertion, reliability, and complications. Patients and Methods: This prospective randomized study included 92 neonates scheduled for CVC insertion. They were divided into two groups: Group A (46 neonates) underwent the US-guided approach and Group B (46 neonates) underwent the surgical approach. The number of attempts and the duration of the procedure were documented in both groups. In addition, intraoperative and postoperative complications were recorded. Results: Each of patient's age, gender, weight, and the indication of catheter insertion were statistically comparable between the two groups. The number of trials showed a significant increase in Group A (1.52 vs. 1.07 in Group Bp <0.001). Nevertheless, the time of the procedure was significantly decreased in the same group (3.68 vs. 10.21 in Group Bp <0.001). Table 2 summarizes the previous findings. Failure was encountered only in one case in Group A (2.2%), which was converted to the open surgical technique. In general, the incidence of complications showed no significant difference between the two approaches. Conclusion: Although US-guided CVC insertion is associated with an increased number of trials, the duration of the procedure is significantly diminished with its use. Furthermore, it has a high success rate in addition to a comparable complication profile with the traditional surgical method.

The Impact of Sevoflurane and Propofol Anesthetic Induction on Bag Mask Ventilation in Surgical Patients with High Body Mass Index.

BACKGROUND AND AIMS: Obesity is associated with restrictive ventilatory pattern which causes rapid oxygen desaturation. Although obesity is considered as a risk factor for difficult airway management, failure to achieve effective bag mask ventilation (BMV) can be catastrophic. This study tried to assess the effect of both propofol and sevoflurane on the efficacy of BMV during anesthetic induction in obese patients. PATIENTS AND METHODS: A total of 200 cases were included, and they were randomly divided into two equal groups; Group S which included 100 cases who underwent sevoflurane induction, and Group P which included the remaining 100 cases who underwent propofol induction. RESULTS: No statistically significant difference was detected between the two groups regarding patient and air way characteristics (P > 0.05). Difficult BMV (DBMV) was encountered in 19% and 37% of cases in Groups S and P, respectively. The incidence of DBMV was significantly increased in the P group (P = 0.005). Furthermore, the severity of difficulty was more marked in the P group. Logistic regression analysis revealed that thyromental distance, presence of macroglossia, presence of beard, lack of teeth, history of snoring, as well as propofol induction were risk factors for DBMV. CONCLUSION: Sevoflurane can facilitate BMV and provide better intubation conditions in comparison to propofol during anesthetic induction in morbidly obese patients. Moreover, decreased thyromental distance, presence of macroglossia and beard, lack of teeth, and history of snoring are considered preoperative indicators of DBMV.

Hepatic Protective Effect of Dexmedetomidine after Partial Hepatectomy Surgery: A Prospective Controlled Study.

BACKGROUND: Inflow occlusion of the portal triad is a common blood loss-reducing method during hepatectomy which may induce ischemic-reperfusion injury of the remaining parts of the liver. Dexmedetomidine is used for reducing ischemic-reperfusion injury in hepatectomy. AIM: The aim of this study was to assess the protective effect of dexmedetomidine on liver after partial hepatectomy using inflow occlusion. SETTING AND DESIGN: This prospective controlled, double-blinded, randomized study included any patients of either sex with age between 20 and 70 years, those in physical status American Society of Anesthesiologists Classes I and II, and those who were planned for partial hepatectomy. PATIENTS AND METHODS: Patients with elective hepatectomy were randomized into dexmedetomidine group, which received dexmedetomidine at 0.3 mg/kg/h, and control group, which received a placebo. STATISTICAL ANALYSIS: Statistical analysis was performed using IBM SPSS software version 18. Data were tested using Kolmogorov-Smirnov test, independent t-test or Mann-Whitney U-test, and Chi-square or Fisher's exact test. The statistical significance was considered at P < 0.05. RESULTS: Serum albumin, aspartate aminotransferase, alanine aminotransferase, prothrombin time were higher in control group in comparison to dexmedetomidine group. Hypotension duration was lower in control group in comparison to dexmedetomidine group. Vasoconstrictor usage, amount of blood loss, and colloid, crystalloid, and blood given to patients were higher in control group in comparison to the study group. CONCLUSIONS: Dexmedetomidine can protect the liver during hepatic resection surgery with inflow occlusion with decreasing blood loss and need for blood transfusion.
