The nine-item instrument produced valid and reliable measures of faculty supervision. However, a significant amount of halo effect biased such measures. G-studies may help identify the type and magnitude of rater biases affecting resident-generated faculty supervision evaluations, and can be useful for interpreting their results, especially if personnel decisions (e.g., tenure, promotion) rely on such measures.
The successful location of the subarachnoid or the epidural space at the first attempt is influenced by the quality of patients' anatomical landmarks, the adequacy of patient positioning and the provider's level of experience.
Justificativa e Objetivos
R e s u l t a d o s -Qu a r e n ta e n o v e pa c i e n t e s ( 2 4 , 0 1 % ) apresentaram SpO 2 menor que 92% durante o período de observação. Foram indicadores de hipoxemia [relação de chances (limites de 95% de confiança)]: idade maior que 55anos [4,32 (1,70; 10,95)], SpO 2 pré-operatória menor que 95% [7,47 (1,50;37,11)], anestesia geral com enflurano [14,53 (2,54;82,93)], hipoventilação detectada clinicamente [34,82 (11,46;105,84) [7.47 (1.50; 37.11)], general anesthesia with enflurane [14.53 (2.54; 82.93)], and clinically detectable hypoventilation [34.82 (11.46; 105.84
]. A PAS e a FC foram significativamente mais elevadas nos pacientes hipoxêmicos.
Conclusões -Existem fatores significativamente associados à ocorrência de hipoxemia pós-operatória, enquanto o uso do o x í m e t r o d e p u l s o p e r m i t e a u t i l i za ç ã o s e l e t i v a d e oxigenioterapia no período pós-anestésico imediato.
