RESUMO
Introducción: El aumento de la expectativa de vida determina un incremento en la incidencia de enfermedades con indicación quirúrgica. El avance en las técnicas quirúrgicas, los cuidados intensivos y el conocimiento más profundo del proceso de envejecimiento tiende a favorecer la disminución de la morbimortalidad perioperatoria del paciente geriátrico. Objetivo: Determinar la incidencia de complicaciones intra y posoperatorias en pacientes geriátricos durante la cirugía abdominal mayor electiva. Métodos: Se realizó un estudio observacional descriptivo, de corte transversal a 373 pacientes geriátricos programados para intervención quirúrgica abdominal mayor desde enero de 2017 hasta diciembre de 2019 en el Hospital Clínico Quirúrgico Dr. Miguel Enríquez. Se registró la incidencia de complicaciones perioperatorias relacionándolas con las variables de estudio. Resultados: Las complicaciones más frecuentes fueron las cardiovasculares. La mortalidad fue escasa. Conclusiones: Las complicaciones perioperatorias detectadas en los pacientes geriátricos estudiados, se relacionan con las enfermedades previas, el tipo y la envergadura de la cirugía y con el tiempo quirúrgico(AU)
Introduction: The increase in life expectancy determines an increase in the incidence of diseases with surgical indication. Advances in surgical techniques, intensive care and deeper understanding of the aging process tend to favor the reduction of perioperative morbidity and mortality among geriatric patients. Objective: To determine the incidence of intraoperative and postoperative complications among geriatric patients during elective major abdominal surgery. Methods: A descriptive, cross-sectional and observational study was carried out with 373 geriatric patients scheduled for major abdominal surgery from January 2017 to December 2019 at Dr. Miguel Enríquez Clinical-Surgical Hospital. The incidence of perioperative complications was recorded, relating them to the study variables. Results: The most frequent complications were the cardiovascular ones. Mortality was low. Conclusions: The perioperative complications identified among the geriatric patients studied are related with previous diseases, with the type and extent of surgery, and with the surgical time(AU)

Older patients undergoing surgery have reduced physiologic reserve caused by the combined impact of physiologic age-related changes and the increased burden of comorbid conditions. The preoperative assessment of older patients is directed at evaluating the patient's functional reserve and identifying opportunities to minimize any potential for complications. In addition to a standard preoperative evaluation that includes cardiac risk and a systematic review of systems, the evaluation should be supplemented with a review of geriatric syndromes. Age-based laboratory testing protocols can lead to unnecessary testing, and all testing should be requested if indicated by underlying disease and surgical risk.

Increasing life expectancies paired with age-related comorbidities have resulted in the continued growth of the elderly surgical population. In this group, age-associated changes and decreased physiological reserve impede the body's ability to maintain homeostasis during times of physiological stress, with a subsequent decrease in physiological reserve. This can lead to age-related physiological and cognitive dysfunction resulting in perioperative complications. Changes in the cardiovascular, pulmonary, nervous, hepatorenal, endocrine, skin, and soft tissue systems are discussed as they are connected to the perioperative experience. Alterations affect both the pharmacodynamics and pharmacokinetics of administered drugs. Elderly patients with coexisting diseases are at a greater risk for polypharmacy that can further complicate anesthetic management. Consequently, the importance of conducting a focused preoperative evaluation and identifying potential risk factors is strongly emphasized. Efforts to maintain intraoperative normothermia have been shown to be of great importance. Procedures to maintain stable body temperature throughout the perioperative period are presented. The choice of anesthetic technique, in regard to a regional versus general anesthetic approach, is debated widely in the literature. The type of anesthesia to be administered should be assessed on a case-by-case basis, with special consideration given to the health status of the patient, the type of operation being conducted, and the expertise of the anesthesiologist. Specifically addressed in this article are age-related cognitive issues such as postoperative cognitive dysfunction and postoperative delirium. Strategies are suggested for avoiding these pitfalls.
