Background:
Intravenous injection of rocuronium is associated with withdrawal responses which are attributable to the pain from the injection of rocuronium. Several methods have been proposed to abolish and attenuate rocuronium-induced pain. We hypothesized priming dose of rocuronium could reduce withdrawal responses associated with administering a second large dose of rocuronium for tracheal intubation. We compared the efficacy of the priming dose technique of rocuronium with intravenous lidocaine as a pre-treatment for the prevention of withdrawal responses associated with rocuronium injection.
Methods:
We recruited 150 patients aged between 18 and 60 years, ASA physical status 1 or 2, who were going to undergo elective surgery requiring general anesthesia. Patients were allocated into three groups. Group C received normal saline, Group L received lidocaine 1 mg/kg, and Group P received rocuronium 0.06 mg/kg 2 minutes before administering a second large dose of rocuronium for tracheal intubation. After the loss of consciousness, rocuronium 0.6 mg/kg was administered intravenously over 10 seconds for tracheal intubation. The withdrawal responses to the injection of rocuronium were evaluated.
Results:
The incidence of withdrawal responses associated with rocuronium injection for tracheal intubation was 56, 50, 24% in group C, group L, and group P, respectively. The incidence of withdrawal responses was lower in group P than group C and group L, but there was no difference between group L and group C.
Conclusions:
Priming dose technique is a useful clinical method to alleviate withdrawal responses associated with rocuronium injection.

01:18Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
01:18Routes of Drug Administration: Enteral
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...

01:22Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...
