Application via mechanical dropper alleviates sufentanil-induced cough: a prospective, randomized, single-blinded trial

Table 2 Incidence and severity of SIC: primary outcome of the study

SIC incidence (%)	Group C	Group M	P
None	79	98^**	0.000
Mild	8	2	0.052
Moderate	11	0^**	0.001
Severe	2	0	0.095
Total incidence	21	2^**	0.000

Note: Group C, sufentanil injected at a rate of 1 ml·s^− 1 via T-connector near the venous catheter, while the same volume of normal saline was added to the mechanical dropper at a similar rate; group M, sufentanil injected into the dropper and normal saline into the T-connector at 1 ml·s^− 1. SIC sufentanil-induced cough
Compared with group C, ^*P < 0.05, ^**P < 0.01
