The objective of this research was to determine the factors associated with the noise level produced by high and low-speed rotary instruments according to usage time, brand, and maintenance. The study was descriptive, observational, prospective, and cross-sectional. A total of 128 rotary instruments, both high and low speed, were used, and the noise level was measured using a sound level meter during cavity preparation on models with natural teeth. The results showed that the average noise levels of the high and low-speed rotary instruments were below 85 decibels (dB). According to usage time, the highest noise level was found between 4 to 5 years for both types of instruments. By brand, the highest noise level for high-speed rotary instruments was found in brand 1, and for low-speed instruments, it was found in brand 3. Finally, according to maintenance, the highest noise level in both types of instruments was found in those that had not received maintenance. It was concluded that the most frequent factor associated with the noise level produced by high and low-speed rotary instruments was maintenance, and all instruments were below the 85 dB permissible exposure limit regulated by MINSA.

(Universidad Privada Norbert Wiener, 2020-02-16) Erribari Sulluchuco, Mirtha Nitza; Giraldo Vicente, Betzabé Maira; Gamarra Bustillos, Carlos
Objective: Systematize the evidence on the effectiveness of the use of external active heating devices in the perioperative period to reduce hypothermia in patients undergoing surgical intervention. Materials and Methods: A retrospective systematic review was carried out, which summarizes the findings of various primary studies. These investigations are an important part of evidence-based nursing to answer clinical questions. Thus, it was restricted to documents using the GRADE system, which allowed the recommendation power to be strengthened. Subsequently, the selected investigations were subjected to critical analysis. Results: Finally, 10 articles were selected, carried out in the present study, the active heating methods are efficient, although some seem to be more efficient than others. Better findings were obtained when warming was extended to the preoperative stage to reduce the occurrence of perioperative hypothermia. For this reason, intervention measures are necessary in order to prevent hypothermia and maintain normal temperature before and during the operation. Conclusions: Active warming methods were shown to be effective in maintaining perioperative normothermia. Being an effective measure (efficient and effective), since it increases body temperature and thermal comfort, patient satisfaction and facilitates venous cannulation, it reduces bleeding, infection of the surgical wound, mechanical ventilation time, use of fluids, vasodilators, morphine and antibiotics, blood pressure and cardiac disorders, reduces hospitalization time and costs. Warming during the intraoperative period is sufficient to effectively prevent hypothermia, both at this stage and in the postoperative period.
