Aim And Objective: The purpose of the study is to compare the effects of rocuronium priming with the combined technique of magnesium pretreatment and rocuronium priming and to investigate whether this pretreatment could further accelerate the onset of neuromuscular blockade during intubation.
Materials And Methods: A double-blinded randomized controlled trial (RCT) clinical study was done on patients at a tertiary care center for six months after obtaining approval from the institutional ethical committee. A total of 150 patients were randomly allocated as Group MP (infusion of 50 mg/kg of MgSo4 over 10 min was given 10 mins prior to premedication and dose of rocuronium 0.06 mg/kg given three minutes), Group P (priming dose of rocuronium 0.06 mg/kg given three minutes before the intubating dose), and Group C (control group with the same volume of 0.9% saline and rocuronium bolus of 0.6 mg/kg on intubation). Parameters such as demographic and hemodynamical data, American Society of Anesthesiologists (ASA) score, Mallampati scoring, neuromuscular monitoring, intubation grading, and number of successful/failed attempts were recorded.
Results: Our results showed that Group MP had a rapid onset of action of rocuronium with 58.90 +/- 4.77 seconds and a longer duration of action of rocuronium with 54.92 +/- 10.39 minutes, which are statistically significant compared to Group P (onset of action of ROC 106.70 +/- 4.24 seconds and duration of action rocuronium 45.88 +/- 6.22 minutes) and Group C (onset of action of ROC 154.56 +/- 11.39 seconds and duration of ROC 40.56 +/- 3.96 minutes). The maximum number of patients in Group MP (33 patients) showed good intubation conditions compared to Group P (23 patients) and Group C (16 patients), which was statistically significant.
Conclusion: We conclude that magnesium sulfate pretreatment in combination with rocuronium priming (Group MP) considerably accelerates the onset of rocuronium action, increases the duration of action of rocuronium, and enhances the intubation procedure without any adverse effect of rocuronium and magnesium sulfate.

Skeletal muscle relaxants have their place in everyday use in numerous anesthesiological procedures, such as preparing a patient for surgery, supporting mechanical ventilation, and performing effective intubation. These drugs can be divided, based on their mechanism of action, into depolarizing skeletal relaxants, such as succinylcholine, and non-depolarizing skeletal muscle relaxants. Non-depolarizing agents are further categorized, based on their structure, into steroidal (eg, rocuronium) and benzylisoquinoline (eg, atracurium) compounds.

Article Synopsis
- Anaesthesia primarily depresses the central nervous system, impacting various physiological systems during procedures like hysteroscopy and endometrial ablation.
- In this case study, preoxygenation helped maintain oxygen levels during apnoea, but Propofol significantly lowered the patient's respiratory rate, leading to apnoea.
- The cardiovascular effects included a spike in heart rate from sympathetic stimulation during intubation and hypotension from anaesthesia induction, which was managed with ephedrine and required adjusted dosages of rocuronium and sugammadex for muscle paralysis reversal.

Article Synopsis
- * Sugammadex can reverse the effects of rocuronium-induced neuromuscular blockade but may also provoke anaphylaxis, indicating a need for better treatment options.
- * Research into the antibodies of patients with rocuronium sensitivity found a diverse range that can activate anaphylaxis; high-affinity antibodies capable of reversing rocuronium effects were isolated, suggesting new avenues for diagnosis and treatment.
