Background: The qulity of recovery-40 questionnaire (QoR-40) has been widely used to assess quality of recovery after surgery, but it is too lengthy for clinical use. The short form of QoR-40, QoR-15, has been validated in many languages; however, an official Korean version of the QoR-15 (QoR-15K) has not yet been established. This study aimed to develop and validate QoR-15K.Methods: Based on the previously-validated Korean QoR-40, we selected 15 items; the QoR-15K was patterned on the original QoR-15. We analyzed 210 subjects who had been scheduled for elective surgery under general anesthesia. The patients completed the questionnaire before surgery and on postoperative days one and two. The validity, reliability, and responsiveness of the QoR-15K were evaluated. Results: We obtained excellent convergent validity on visual analog scale for recovery (VAS) (ρ = 0.88, P < 0.001). The duration of anesthesia, post-anesthesia care unit, and overall hospital stay with the QoR-15K showed a significant negative correlation (ρ = -0.183, -0.151, and -0.185, respectively). Cronbach’s α was 0.909. Cohen’s effect size and standardized response mean were 0.819 and 0.721. The recruitment and completion rate were 92.9% and 100%, respectively. We based the above calculations on the results obtained on the first day following surgery.Conclusions: The validity and reliability of the QoR-15K are comparable to those of the English version. The QoR-15K would be a good instrument to assess the quality of recovery in Korean patients after surgery.
El síndrome de Wallenberg es el accidente cerebrovascular isquémico más común de la circulación posterior, causado por una obstrucción aterotrombótica en la arteria vertebral o la arteria cerebelosa posteroinferior. Esta oclusión origina una isquemia en la porción lateral del bulbo que resulta en la triada representativa del síndrome de Horner, ataxia ipsilateral a la lesión y alteraciones sensitivas. El riesgo de padecer este cuadro es mayor si se tiene variaciones anatómicas tales como una arteria vertebral hipoplásica y/o duplicada. Se presenta el caso de una mujer de 45 años admitida por hipoestesia en el lado derecho del rostro y en el hemicuerpo izquierdo, así como disfagia y vómitos. La resonancia magnética reveló una lesión isquémica en la zona bulbar lateral derecha; en la angiorresonancia se evidenció una arteria vertebral derecha hipoplásica, en tanto que la angio-TEM del cuello mostró una arteria vertebral derecha hipoplásica y bifurcada. En base a la clínica y exámenes radiológicos se confirmó el diagnóstico de Síndrome de Wallenberg, causado por isquemia en el territorio de la arteria vertebral derecha hipoplásica bifurcada.
