Magnesium sulfate reduces the rocuronium dose needed for satisfactory double lumen tube placement conditions in patients with myasthenia gravis

Table 2 Anaesthesia and emergence data. Data are presented as mean (standard deviation) or number of patients

	Magnesium sulfate group (n = 23)	Normal saline group(n = 22)	P
Rocuronium dosage (mg.kg^− 1)	0.10 (0.05)	0.28(0.17)	< 0.0001*
Intubation condition score (excellent/fair/poor)	23/0/0	16/5/1	0.027*
Propofol concentration when intubation (μg.ml⁻¹)	3.15(0.36)	3.37(0.91)	0.267
Time of TOF ratio 90% recovery from the last dose of rocuronium before intubation (minutes)	50.5 (42.4)	47.2(42.2)	0.881
Time of extubation time from the end of operation (minutes)	9.4(5.6)	10.5(6.8)	0.561
Postoperative neostigmine medication (no/yes)	17/6	15/7	0.672
Postoperative pain intensity (free/mild/moderate)	15/7/1	8/6/6	0.056
Riker sedation and agitation scale in PACU (non-agitated/agitated)	23/0	16/6	0.009*

Intubation condition score was evaluated based on Copenhagen Consensus Conference scoring system which includes the ease of laryngoscopy, vocal cord position and/or movement and response to intubation (cough or diaphragmatic movement) [16, 17]
Excellent: all qualities are excellent; Good: all qualities are either excellent or good; Poor: difficult of laryngoscopy, vocal cords closed or vigorous/sustained response to intubation
*P value < 0.05 was considered significant
