The calculation of body mass index and duration of anesthesia is the first step of a series of actions performed anesthesia on pediatric patients who planned to undergo anesthesia . The calculation of body mass index and duration of anesthesia determine the smoothness of anesthesia , and the patient's recovery period after general anesthesia. The study is to determine the relationship of body mass index and duration of anesthesia with conscious recovery time after general anesthesia in children using observational analytic cross sectional survey approach. The site of research is in recovery room of The Central Surgery Installation RSUD Kebumen Central Java with as many as 44 research sample consists of body mass index and duration of anesthesia, with postoperative assessment instruments Steward score. The result is patients with conscious recovery time after general anesthesia slowly, over 30 minutes is a patient with a body mass index is not ideal that 13 people ( 68.42 % ) of the total sample whereas patients who recovered quickly in less than or equal to 30 minutes as many as 17 people ( 72 % ) with an ideal tubu mass index of the total sample . From the statistical test Chi-square computer program values obtained value , the probability asymp . Sig . ( 2 - sided ) : 0,008 which means there is a relationship of body mass index of anesthesia with the patient recovery time , and patients recover with time after general anesthesia consciously slowly , over 30 minutes is a patient with a long lebi anesthesia time of 1 hour 12 people ( 75 % ) of the total sample whereas patients who recovered quickly in less than or equal to 30 minutes of 20 people ( 71.43 % ) with a time of anesthesia faster than the total sample . From the statistical test Chi-square computer program values obtained value , the probability asymp. Sig. ( 2 - sided): 0,003 which means there is a long-standing relationship with the anesthesia recovery time of patients, so there is a relationship of body mass index and duration of anesthesia with conscious recovery time

PENDAHULUANAnestesi yang ideal akan bekerja secara cepat dan baik serta mengembalikan kesadaran dengan cepat segera sesudah pemberian anestesi dihentikan (Majid dkk., 2011). Anestesi baik intravena atau inhalasi akan berpengaruh pada kondisi tubuh post operasi, antara lain: mual muntah post anestesi, hipertensi/ takikardi, obstruksi jalan nafas, dan menggigil (Brunton, 2011).Pasien yang mengalami komplikasi pasca operasi dengan general anestesi yang tidak segera ditangani akan berdampak kematian bagi pasien. Komplikasi yang sering terjadi meliputi komplikasi respirasi, komplikasi, kardiovaskuler, hipotermia, hipertermia dan gelisah pascaoperasi (Baradero, 2008). Laporan umum mencatat kejadian kematian di Amerika rata-rata 0,2-0,6% dari operasi dan kematian yang disebabkan oleh anestesi 0,03-0,1% dari seluruh anestesi yang diberikan (Nainggolan, 2011) Sekitar 90% pasien sadar penuh dalam waktu 15 menit. Tidak sadar lebih dari 15 menit dianggap prolonged, bahkan pasien yang sangat rentan harus merespons stimulus dalam 30 hingga 45 menit setelah anestesia. Sisa efek sedasi dari anestesia inhalasi dapat mengakibatkan keterlambatan pulih sadar, terutama setelah prosedur operasi yang lama, pasien obesitas (Mecca, 2013). Pergerakan akan mencegah kekakuan otot dan sendi sehingga juga mengurangi nyeri, menjamin kelancaran peredaran darah,
