Variabilidad de la tensión arterial durante colecistectomía laparoscópica en hipertensos

introduction: the vesicular lithiasis requiring surgical treatment is associated with the blood pressure frequency. nowadays, most of cholecystectomies are carried out by minimal invasive surgery.objectives: to describe the blood pressure variability and the possible significant complications in hypertensive patients during laparoscopic cholecystectomy, as well as the type of hypertensive patient (treated or no-treated), is more prone to blood pressure fluctuations in the intraoperative time. method: a longitudinal, descriptive and retrospective study was conducted in the national center of minimal access surgery from january, 2007 to december, 2007 in patients operated on due to laparoscopic cholescystectomy with a history of high blood pressure. results: the most variability of the mean blood pressure was noted after pneumoperitoneum and to place patient in inverse trendelemburg position with values of 91±25 mmhg and 94±23 mmhg, respectively without appearance of complications. from the patients treated the 66.7% and the 47.6% of no-treated, had a drop of more than the 20% of mean blood pressure after anesthesia induction, for remainder, the measurement times for both groups behave of similar way. conclusions: despite the variability found in the blood pressure figures, there were not clinical and significant complications during the intraoperative time.
