Compare Onset Time of Cisatracurium for Tracheal Intubation with and without Priming Dose of Rocuronium
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2019, Vol 6, Issue 11
Abstract
Background: Priming is one of those techniques in which a small dose of non-depolarizing muscle relaxants is administered followed by a large intubating dose. Cisatracurium is the newly introduced drug with Hoffman elimination. The problem with its use is delayed onset of action. The present study was conducted to compare the onset of cisatracurium for tracheal intubation with and without priming dose of rocuronium. Materials and Methods: A total of 60 American Society of Anesthesiologist physical Status Ι and ΙΙ patients undergoing surgery under general anesthesia were included in the study. Patients were divided into two groups of 30 each. Patients in Group R received priming dose of rocuronium 0.06 mg/kg before intubating dose of cisatracurium (0.14 mg/kg). Group C patients did not get any priming, only normal saline was given before intubating dose of cisatracurium (0.15 mg/kg). Results: Time gap between administration of the cisatracurium and complete loss of T1 was recorded as intubation time. The intubation time was significantly less in Group R, i.e., 130 ± 11.02 s as compared to Group C, i.e., 230.33 ± 12.82 s. The intubating conditions were similar in both the groups. The hemodynamic changes were statistically insignificant. The time to 25% recovery of the T1 response is defined as the clinically effective duration of neuromuscular block. The rate of recovery is described by the recovery index, which is defined as the time from 25% to 75% T1 recovery. Conclusion: Priming with rocuronium decreased the onset time without increasing the clinical duration of action or recovery index.
