BackgroundPatients undergoing craniotomy operations are prone to various noxious stimuli, many strategies are commenced to provide state of analgesia, for better control of the stress response and to overcome its undesired effects on the haemodynamics and post-operative pain. Scalp nerves block are considered one of these strategies. This study was conceived to evaluate the effect of addition of hyaluronidase to the local anaesthetic mixture used in the scalp nerves block in patients undergoing elective craniotomy operations.Methods64 patients undergoing elective craniotomy operations were enrolled in this prospective randomized, double-blind comparative study. Patients were randomly assigned to two groups. Group LA, patients subjected to scalp nerves block with 15 ml bupivacaine 0.5%, 15 ml lidocaine 2%, in 1:400000 epinephrine. Group H as Group LA with15 IU /ml Hyaluronidase.ResultsPatients in the H group showed lower VAS values for 8 h postoperative, compared to the LA group. The haemodynamic response showed lower values in the H group, compared to the LA group. Those effects were shown in the intraoperative period and for 6 h post-operative. No difference was detected regarding the incidence of complications nor the safety profile.ConclusionOur data supports the idea that addition of hyaluronidase to the local anesthetic mixture improves the success rates of the scalp nerves block and its efficacy especially during stressful intraoperative periods and in the early postoperative period. No evident undesirable effects in relation to the addition of hyaluronidase.Trial registrationClinical Trial registry on ClinicalTrials.gov, NCT 03411330, 25-1-2018.
Background: Obesity is a widely spread health problem the complications of which are too many whether general or obstetric complications.Objective: The aim of this observational study is to evaluate the impact of increased BMI of nulliparous women on progress of labor, incidence of peri-partum complications (1ry outcome) and neonatal outcome of these women (secondary outcome). Patients and Methods:In this prospective observational study, 150 primigravidas in labor were recruited in Mit Ghamr General Hospital between November 1st, 2019 and April 30th, 2020 and categorized into 5 groups according to WHO BMI classification; Group A contained 50 patients with BMI 18.9-24.9, group B 50 patients with BMI 25-29.9, group C1 20 patients with BMI 30-34.9, group C2 20 patients with BMI 35-39.9 and group C3 10 patients with BMI at least 40. Recruited patients were monitored for their progress of labor (in terms of time of cervical dilation from 4 cm to 10 cm, the accordingly calculated rate of cervical dilation and duration of head descent) and their development of peri-partum complications (cervical dystocia, shoulder dystocia, arrest of head descent, the subsequent potential need for CS, 3rd and 4th degree perineal tears, 1ry post-partum hemorrhage, retained placenta). Neonatal outcome was observed by measuring fetal birth weight, APGAR score at 1 minute and 5 minutes, subsequent potential need for NICU admission and occurance of neonatal jaundice.Results: A statistically significant difference was found regarding progress of labor and neonatal outcome with women in obese groups (C1, C2, C3) having slower progress and worse neonatal outcome, while no statistically significant difference was found regarding mode of delivery and peri-partum complications. Conclusion:Obese women in labor considered high-risk cases that required special measures whether on short-term or long-term basis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
