Postoperative residual curarization at the post-anesthetic care unit of a university hospital: Estudio de corte transversal. Postoperative residual curarization has been related to postoperative complications.

To determine the prevalence of postoperative residual curarization in a university hospital and its association with perioperative conditions. A prospective registry of patients in a period of 4 months was designed to include ASA I-II patients who intraoperatively received nondepolarizing neuromuscular blockers. Organon, Ireland was measured immediately upon arrival at the postanesthetic care unit and 30 s later.

Postoperative residual curarization was detected in A high prevalence of postoperative residual curarization persists in university hospitals, despite a reduced use of “long-lasting” neuromuscular blockers. Strategies to assure neuromuscular monitoring practice and access to therapeutic alternatives in this setting must be considered. Intraoperative neuromuscular blockers using algorithms and continued education in this field must be priorities within anesthesia services.

Nondepolarizing neuromuscular blocking agents ND-NMBA have commonly used in surgical units to facilitate endotracheal intubation and during procedures under general anesthesia to provide adequate surgical conditions or optimize ventilatory support. This study aimed to assess the prevalence of PORC on admission to the PACU of patients treated at a university hospital as our primary objective, and to determine possible associations with demographic aspects and perioperative variables.

The size of the representative sample of the surgical population was defined and data were collected continuously during business hours during the time in which the expected number of patients was completed.

All patients were invited to participate and gave their consent at admission to the surgical unit. Subjects with previous diagnosis of neurological or neuromuscular disease, those who were transferred to other places different to PACU or who requiring postoperative mechanical ventilation, were excluded.

A second-year resident of Anesthesiology or technical assistant previously trained and blinded to perioperative management were responsible to perform NMRM immediately for admission to PACU and 30 s later. After cleaning the site, an electrode distal was positioned at the point where the proximal flexor line of the wrist crosses the radial side of the flexor carpi ulnaris; the proximal electrode was placed 3-Icm away from the first one, on the ulnar nerve area.

Simultaneously, surface temperature was determined by a sensor placed on the thenar eminence. The TOF test was applied by four stimuli of 0. In regards to the test and results, the anesthesiologist remained blinded to control the treatment bias. The prevalence of the outcome of interest was calculated as follows:. Processing and data analysis was performed using SPSS Categorical variables are described as proportions and percentage distributions while numerical variables as means and standard deviations SD.

Differences among groups were evaluated based on analysis of variance of one way. A total of subjects accepted to participate in this study. Other demographic characteristics related to surgery showed no differences between groups Table 1. Additionally, a non-significant trend to increased cases of PORC was found when combinations of these drugs Table 2 were presented. To clarify the influence of the temperature measured in the thenar eminence on the TOF test results, we performed a concordance analysis.

Coefficient of determination R 2 showed a value of 0. PORC incidence reported in our study was We would like to highlight the use of doses close to DE95x2 in the sample analyzed and a total preference for the use of ND-NMBA of steroid type, whereas a global trend is toward the use of lower doses of these drugs and a reduction of their use only for selected cases.

Our data show that pancuronium is associated with a greater probability of PORC as reported by previous studies. We believe our results may be due to multiple factors. In the first instance, there are barriers on awareness to prevent and detect this adverse event within anesthesia teams this adverse event. Additionally, the absence of other therapeutic alternatives such as benzylisoquinolinics, which have been associated with a lower incidence of PORC and interindividual variability, 32,33 limits the staff practicing in public hospitals, unable to decide between different current therapeutic options in diverse clinical scenarios.

Nevertheless and as shown by our results, a proportionally smaller pancuronium use has been observed. We estimate a further reduction in the use of this drug for the coming years, as usual option in operating rooms. It has been suggested that routine use NMRM intraoperatively, could reduce the incidence of PORC, 34 and thus decrease complications associated with this morbid condition. It is well known that clinical tests as elevation of the head or feet, evaluation of minute volume among others, have a poor positive predictive value for detecting PORC.

Our finding about the correlation between lower thenar temperatures and a higher proportion of PORC deserves further analysis. A failed statistical causality between these temperatures coefficient of determination and the main event can be explained by the high variability between central temperatures and peripheral areas. This study represents one of the first publications in Latin America in order to delimit this problem at public university hospitals 14,32,37 ; scenarios where limitations in alternative therapies and devices for monitoring and preservation of homeostasis during surgery are frequent.

In regards to standardization of TOF test arrival upon PACU, we follow the guidelines for NMRM, considering that the voltages used in our study are valid for the evaluation of neuromuscular function for awake patiens.

Current prevalence of PORC in a Latin American university hospital representative of other institutions in the area, is as high as reported by similar studies around the world. Despite an apparent reduction in the use of long lasting ND-NMBA an unacceptably high incidence of this adverse event persists. Given the high prevalence of this problem, we strongly suggest to enhance strategies to stimulate the routine practice of NMRM in despolatizantes hospitals and efforts to assure availability of different therapeutic options for this purpose, as well as to encourage surgical teams to build ND-NMBA using algorithms in order to offer the blosueantes possible perioperative care to our patients.
