An epidemiological, observational, analytical and retrospective study of cases and controls was conducted with women undergoing elective cesarean section under spinal anesthesia at the Carlos Manuel de Céspedes Hospital in Bayamo, Granma province, from February 2013 to December 2015; with the objective of identifying the risk factors hypothetically related to the appearance of postpuncture dural headache in obstetric patients undergoing elective cesarean section.All the patients who gave their consent to participate, their data collection form was prepared for the study that collected the variables of the study. In addition, with each hypothetically influencing factor, the estimate of the benefit frame (OR) and its 95% confidence intervals (95% CI) and the hypothesis test of Chi to Square were performed. The age less than 25 years, the history of previous headache, the diameter of the needle of 20 and 22G, the greater number of puncture attempts and the position of the seated patient are the risk factors related to the appearance of post-puncture headache dural, but not the body mass index higher than 30 in obstetric patients undergoing elective cesarean section.

In all surgical procedures, the organism presents different physiological alterations that expose the patient to a series of difficulties that, if not taken into account, can cause very severe complications in the post-anesthetic awakening of elderly patients. A longitudinal prospective cohort study was carried out on elderly people who underwent laparoscopic video surgery at the general provincial hospital "Carlos Manuel de Céspedes de Bayamo, from the Cauto region during the period from January 1, 2019 (,) to December 31, 2019. December 2021; with the aim to identify the risk factors related to a delay in post- anesthetic awakening. It was established that the exposed cohort consisted of 39 elderly people with delayed post-anesthetic awakening in the study period who met the inclusion criteria. The magnitude of the associations was estimated by calculating the relative risks (RR) of delay. There is an association between patient-dependent risk factors: smoking, obesity, presence of comorbidities and use of chronic pharmacological therapy, with a delay in post-anesthetic awakening in the elderly. The duration of the intervention, fasting time greater than 12 hours and hypoglycemia were the factors dependent on the surgical-anesthetic act associated with a delay in post-anesthetic awakening in the elderly.

An analytical, cross-sectional study was carried out in patients undergoing major elective surgery under general orotracheal anesthesia, at the "Carlos Manuel de Céspedes" University Provincial Hospital of Bayamo, in the period from January to December 2018, with the objective of evaluating the effectiveness of predictive tests of difficult intubation: Mallampati, Patil-Aldreti test, sternomentonian distance, and interincisive distance. For the calculation of the sample, the professional statistical program Epidemiological Analysis of Tabulated Data was applied, resulting in 269 patients, who were selected in the anesthesia office and applied the tests, after signing the informed consent. For the information processing, descriptive and inferential statistics were used. According to the Youden index, the interincisive distance was unsurpassed in effectiveness in all the tests performed, following the sternomentonian distance; The Mallampati test was the one with the lowest predictive value. Combinations of tests can increase the diagnostic value compared to the value of each test alone.

A prospective longitudinal cohort study was conducted in 470 patients undergoing surgery for gallstones by laparoscopic surgery provincial Hospital "Carlos Manuel de Céspedes in Bayamo, from the Cauto region during the period January 2012 to December 2014, with the aim to identify risk factors hypothetically related to the occurrence of intraoperative cardiorespiratory complications during anesthesia. The exposed cohort consisted of 147 patients who developed complications; Primary information was obtained from the medical records of operated patients. He also performed with each hypothetically influential factor, estimates of relative risk (RR) and confidence intervals 95% (95%) and hypothesis testing chi-square. Age, hypertension, ischemic heart disease were identified as the most important risk factors in the occurrence of cardiac complications in anesthesia for laparoscopic cholecystectomy video.

A prospective longitudinal cohort study was performed in patients with breast cancer operated surgically with the use of total intravenous anesthesia in the provincial hospital Carlos Manuel de Céspedes de Bayamo, from the Cauto region during the period from January 1 from 2014 to December 31, 2016, with the aim of identifying the risk factors hypothetically related to the appearance of respiratory complications. It was established that the exposed cohort was constituted by 79 patients who developed complications during the study period and met the inclusion criteria. The diagnosis of respiratory complications was made during the entire surgical procedure and finished. The magnitude of the associations was estimated by calculating the relative risks (RR) of complications. The age of the patient equal to or greater than 65 years, and smoking were the surgical risk factors depending on the patient related to the onset of respiratory complications in breast cancer surgery with total intravenous anesthesia, not alcoholism. Anemia, obesity, low weight and recent respiratory tract infection were surgical risk factors dependent on associated diseases related to the appearance of respiratory complications. The ASA III-IV classification and the surgical time of more than three hours were surgical risk factors related to surgery related to the appearance of respiratory complications.
