Clinical evaluation of a new formulation of propofol in a medium-chain and long-chain triglycerides emulsion in dogs

Effects of Cisatracurium in Sevoflurane and Propofol Requirements in Dog-Undergoing-Mastectomy Surgery

The purpose of the present study was to test whether the addition of cisatracurium in combination with propofol and sevoflurane would result in a change in doses of used anesthetic drugs. Ten dogs (Group A) undergoing elective unilateral mastectomy surgery were included in the study. To induce and maintain anesthesia, subjects received propofol and sevoflurane at varying doses; analgesia was performed with remifentanil. After three months, the same subjects (Group B) underwent contralateral mastectomy and received the same anesthetic protocol with the addition of cisatracurium at a dosage of 0.2 mg/kg−1. The following parameters were monitored during anesthesia: heart rate, systolic blood pressure, end-tidal CO2, oxygen saturation, halogenate requirement, and rectal temperature at baseline (T0), induction (T1), 5 (T5), 10 (T10), 15 (T15), 20 (T20), 25 (T25), 30 (T30), and 35 (T35) time points. In Group A, halogenate requirement was reduced at all the time points other than T1 (p < 0.001); in Group B, the percentage of halogenate requirement was already reduced at T1 and remained constant during the experimental period, showing no significant intragroup differences. The dose requirements of sevoflurane and propofol varied significantly between the two groups, with significantly lower dosages in the Group B (the cisatracurium-treated group). Moreover, patients treated with cisatracurium showed a stable anesthetic plan. The nondepolarizing-muscle-relaxant cisatracurium besylate could be considered a useful adjunct to anesthetic protocols.

Evaluation of efficacy and safety of propofol in the treatment of procedural sedation/anesthesia in neonates: A protocol for systematic review and meta-analysis

BACKGROUND

In newborns, propofol anesthesia is commonly utilized. Propofol is increasingly being shown to be effective and safe in treating procedural sedation and anesthesia in neonates. This research aims to evaluate the efficacy and safety of propofol in neonates using systematic review and meta-analysis methodologies.

METHODS

A thorough review and meta-analysis of studies on propofol anesthesia in neonates will be conducted. Conduct comprehensive searches in Web of Science, PubMed, Cochrane Library, EMBASE database, WanFang database, and Chinese biomedical literature database before May 25, 2021, to obtain published and qualified research. Two reviewers will assess the quality of the included papers and extract the data independently. Then, for meta-analysis, we will utilize RevMan 5.3 software.

RESULTS

This study will pool the data of separate trials to analyze the efficacy and safety of propofol in the treatment of procedural sedation/anesthesia in neonates.

CONCLUSION

Our findings will give strong data for determining whether propofol is an effective treatment for procedural anesthesia in neonates.
