Do insecticide-treated bednets have an effect on malaria vectors?

Minimally invasive techniques were used for tracheostomy including small horizontal skin incision, limited soft tissue dissection and no suturing. A Retrospective analysis of case sheets of patients who underwent elective tracheostomy by the first and second authors at M S Ramaiah Hospitals in Bangalore between 1st May 2010 and 1st May 2015 was done to compare the result of elective conventional open surgical tracheostomy using midline vertical skin incision with minimally invasive tracheostomy using a short horizontal incision. No statistically significant difference in the peri and post operative complication rate was found. The patterns of intra and post operative complications reflected the choice of the surgical technique-the conventional technique had problems associated with wide dissection, whereas the minimally invasive technique had problems associated with limited exposure. Problems of wound gaping, emphysema and peristomal inflammation were reduced with minimally invasive technique with short horizontal skin incision although statistical difference could not be shown. There was also no statistically significant difference with either technique regards death and decannulation rates. Minimally invasive technique of elective open surgical tracheostomy was found to be as safe as conventional open surgical tracheostomy with midline vertical skin incision in the studied groups.
