Non-knot subcutaneous suture in method of scalp incision suture

Objective To introduce the method of non-knot subcutaneous suture technique and explore the application value of this method in scalp incision suture. Methods One hundred and eighteen patients, admitted to and performed craniotomy in our hospital from January 2008 and January 2015, were enrolled and divided into traditional suture group (n=51) and non-knot subcutaneous suture (n=67) according to the suture methods. The incision suture time, class A or B healing rate and rejection reaction in the two groups were analyzed. Results Time of traditional incision suture was (27.35±1.85) min; there were 45 patients having class A healing and 6 class B healing; 14 times of rejection including 1 having knotting reaction leading to explosion of bone repair material were noted. However, time of non-knot subcutaneous suture was (18.36±2.50) min; and there were 63 patients having class A healing and 4 class B healing; and no rejection was noted. Statistically significant differences were noted between the two groups in the incision suture time and rejection rate (P<0.05), while there was no significant difference in the incision healing level (88.24% vs. 94.03%, P=0.263). Conclusion Non-knot subcutaneous suture technique can shorten the suture time and eliminate the knot rejection, which is easy to learn and promote.
