Use of protocol and evaluation of postoperative residual curarization incidence in the absence of intraoperative acceleromyography – Randomized clinical trial

Perioperative management of elderly patients remains one of the most difficult tasks of modern anesthesiology. Compared with younger patients, people over 60 years of age have a higher risk of developing adverse postoperative outcomes, as a result of age-related decline in physiological functions, the presence of several concomitant diseases, polypragmasia, cognitive dysfunction and specific geriatric syndromes, such as frailty. More than 25 % of this category of people have several chronic diseases of the cardiovascular, nervous, endocrine, hematopoietic, musculoskeletal systems, respiratory, digestive and other systems. In the process of aging, there is also a decrease and some perversion of metabolic processes, a decrease in the reactivity of the body. All of the above, along with the surgical intervention, increases the risk of postoperative complications and perioperative mortality. The recommendations present the definition of the category of elderly and senile patients, provide information about age-related changes in their body that affect anesthesia and intensive care. The main clinical syndromes and symptoms useful in predicting the unfavorable course of the perioperative period are indicated, including frailty, nutritional insufficiency, sarcopenia and cognitive dysfunction. Methods for assessing functional activity and the risk of falls are given separately. Attention is paid to the causes, diagnosis, prevention and treatment of delirium, cardiovascular, respiratory complications. The principles of choosing the method of anesthesia and management of the perioperative period in elderly and senile patients, depending on the features of і nterventions and concomitant pathology, are described.

Introduction : Various drugs and physiologic disturbances affect the action of neuromuscular blocking agents. If some are ignored by the anesthesiologist, e.g. in the absence of monitoring of neuromuscular function, the patient may be at risk of potentially severe consequences related to postoperative residual curarization. Case presentation : A 67-year-old female patient underwent septoplasty under general anesthesia with basic monitoring (three-lead electrocardiogram, non-invasive blood pressure, end-tidal partial pressure of carbon dioxide and SpO2) and a monitoring of neuromuscular function using acceleromyography of the adductor pollicis. General anesthesia was induced with propofol and sufentanil. After neuromuscular monitoring calibration, a single dose of rocuronium was given. Thereafter the trachea was intubated and anesthesia was maintained with sevoflurane. One hundred and two minutes after the administration of rocuronium, a 1% lidocaine solution containing 5µg/mL epinephrine was injected under the mucosa of the nasal septum immediately before the incision. Two minutes after this injection, the train of four ratio was significantly reduced. It took about 13 minutes to recover to the value recorded before the submucosal injection. Conclusion : Epinephrine increases the degree of muscle relaxation achieved by rocuronium, even when neuro-muscular function is recovering. Monitoring is the only mean to rule out a risk of postoperative residual curarization, given the numerous medications and factors interfering with the action of neuromuscular blocking agents.
