Abstract:
Nasopharynx cancer (NPC) occurs frequently in southern China. Radiotherapy (RT) is the standard treatment for this cancer, and weight loss is commonly observed during and for a prolonged period after RT. The determinants of this phenomenon are not well known. The nutritional status of 38 NPC patients was assessed serially before and for a 6-mo period after RT. Body weight, body composition (by dual X-ray absorptiometry), basal metabolic rate (BMR, by indirect calorimetry), and calorie intake (by 3-day dietary record) were documented at pre-RT (T0), end-RT (T1), 2 mo post-end-RT (T2), and 6 mo post-end-RT (T3). The BMI at end-RT was 21.5 +- 3.7 kg/m2 (range = 13.7-27.9 kg/m2) and was significantly lower than that at pre-RT (P < 0.001). Body weight at T1-T3 was significantly lower than that at T0 (P < 0.001). Mean percentage weight loss was 10.8% at end-RT. Fifty-five percent of patients (20 of 30) had 10% weight loss by the end of RT. BMR corrected for body weight did not change significantly among the four time points, but BMRs corrected for lean body mass at T2 and T3 were significantly lower than that at T0 (P < 0.01). Patients' calorie intake generally declined from T0 to T1 (from 1,857 P < 411 kcal to 11,68 +- 549 kcal, P < 0.001) and then increased from T1 to T3. The calorie intakes at T2 and T3 were not significantly different from that at T0 but were significantly higher than that at T1. Patients were in negative energy balance before, during, and up until 6 mo after RT. The recovery in body weight lagged behind the recovery of dietary intake. Eighty-two percent of NPC patients had significant weight loss and was in negative energy balance at the end of RT, which persisted for at least 6 mo. This finding suggests that there is room for improvement in the nutritional status of patients with NPC treated with RT.Cite

Seperti pada dewasa, teknik regional anestesi pada pediatrik kini makin popular digunakan oleh ahli anestesikarena keuntungannya. Namun demikian selalu ada risiko dan kemungkinan timbulnya komplikasi dari setiap tindakan yang dilakukan, termasuk tindakan anestesi regional pada pediatrik. Insidensi komplikasi anestesi regional pada pediatrik tidak banyak, dan kalaupun terjadi komplikasi adalah minor. Komplikasi bisa diakibatkan dari identifikasi ruang saraf, alat, obat, teknis tindakan anestesi regionalnya dan komplikasi lainnya.Walaupun tidak banyak kejadian komplikasi regional anestesi yang dilaporkan pada pediatrik, dan bukanlah komplikasi yang fatal, teknik regional anestesi pada pediatrik harus dilakukan dengan lebih hatihati, pertimbangan risiko dan keuntungannya untuk menghindari terjadinya komplikasi, terlebih karena kebanyakan komplikasi dapat dihindari dengan mempelajari teknik yang benar, menggunakan peralatan yang sesuai, dan sangat menerapkan prinsip keamanan pada pasien dengan baik.

ABSTRACT Airway management is particularly difficult in children with severe congenital anomalies. Such patients are extre- mely sensitive to the respiratory depressant effects of anaesthetic agents. We describe the successful and safe app- lication of caudal anaesthesia for inguinal hernia repair in three cases with severe congenital anomalies (Joubert syndrome, I-cell syndrome). The three patients concerned had congenital anomalies including serious facial defor- mity, respiratory failure and cardiovascular defects. They were administered a single dose of caudal epidural anaest- hesia for inguinal hernia surgery in order to avoid complications associated with general anaesthesia. Caudal block was performed and 1 mL/kg levobupivacaine 0.25% administered. We conclude that caudal epidural anaesthesia can be an effective, suitable and safe anaesthetic technique for inguinal herniotomy without the need for general anaesthesia or endotracheal intubation in children with severe congenital anomalies. Key Words: Caudal anaesthesia, children, congenital anomaly OZET Havayolu yonetimi, ciddi konjenital anomalileri olan cocuklarda ozellikle zordur. Bu tur hastalar anestezik ilaclarin solunum depresan etkilerine karsi asiri derecede duyarlidir. Kaudal anestezinin inguinal herni onarimindaki basarili ve guvenli uygulamasi konjenital anomalileri (Joubert sendromu, I-cell hastaligi) olan uc olguda gosterilmistir. Ilgili uc cocuk hastada, ciddi yuz deformitesi, solunum yetmezligi ve kardiyovaskuler bozukluk dahil konjenital bozuk- luklar vardi. Genel anesteziyle iliskili komplikasyonlari onlemek icin inguinal herni cerrahisinde tek doz kaudal epi- dural anestezi uygulandi. Kaudal anestezide %0.25 levobupivakain 1 mL/kg kullanildi. Kaudal epidural anestezinin, ciddi konjenital bozukluklari olan cocuklarda inguinal herni onarimi acisindan genel anesteziye veya endotrakeal entubasyona gerek duyulmadan etkili, uygun ve guvenli bir alternatif anestezi teknigi olabilecegi sonucuna varildi.
