目的 探讨科学的出院后营养管理对肠道术后新生儿体格追赶的效果,分析影响体格追赶的相关因素。方法 通过营养门诊对出院术后婴儿及社区婴儿进行个体化营养喂养指导和营养咨询,比较两组每月体质量、身长及头围,并随访至生后9月龄。两组生后半年生长趋势行重复测量检验。结果 第1月龄时,手术组患儿体质量、身长、头围均落后于对照组婴儿(P<0.001, P=0.004, P=0.008),第2月龄时,手术组患儿体质量、头围仍落后于对照组(P=0.003,P=0.031),第4月龄时,手术组体质量低于对照组(P=0.012),第5～9月龄,两组体格指标均无明显差异。生后半年内两组的生长趋势差异无统计学意义。前半年身长的增长与出生身长、父母文化以及父亲的不良习惯存在负相关关系,头围的增长与住院天数呈明显负相关关系、与出生以及首诊时的体格状况呈正相关关系。结论 合理喂养对新生儿肠道术后体格追赶有利,帮助其接近正常生长曲线。再次手术可能是导致体质量增长下降的主要因素,但未明显影响身长、头围的正常增长。出生时和就诊时的体格状况、父母教育程度和不良习惯以及住院天数均是影响体格追赶的相关因素。

Objective To investigate the effect of scientific nutrition management after discharge on neonatal physical catch-up after intestinal operation, and to analyze the related factors affecting physical catch-up. Methods Individualized nutritional feeding instruction and nutrition consultation were performed on infants and community infants after discharge from hospital through nutrition clinic. The monthly body weight, body length and head circumference were compared between the two groups, and followed up to 9 months old. The growth trend of the two groups in half a year after birth was tested by repeated measurement. Results At the first month of age, the body weight, body length and head circumference of the patients in the operation group were lower than those in the control group (P<0.001, P=0.004, P=0.008). At the second month, the body weight and head circumference of the operation group were still behind those of the control group (P=0.003, P=0.031), and at the fourth month of age, the weight and head circumference of the patients in the operation group were still lower than those in the control group. The body weight of the operation group was lower than that of the control group (P=0.012), and there was no diffence in the physical indexes between the two groups at the age of 5~9 months. There was no statistical significance in growth trend between the two groups within half a year after birth. The growth of body length in the first half of the year had a negative correlation with the length of birth, parents' culture and father's bad habits. The growth of head circumference had a negative correlation with the length of stay in hospital, and had a positive correlation with the physical condition at birth and at first visit. Conclusion Reasonable feeding is beneficial to the physical catch-up of the newborn after intestinal operation and helps them approach the normal growth curve. Reoperation may be the main cause of weight loss, but it does not affect the normal growth of body length and head circumference. The physical condition at birth and medical visit, parents' education level, bad habit and hospitalization days were all related factors of physical catch-up.

目的 本研究旨在采用连续气道监测法对患者呼吸力学指标进行动态观察,同时监测脑电双频指数（Bispectral index,BIS）和清醒镇静评分（The Observer's Assessment of Alertness/Sedation Scale,OAA/S）,全面系统地评估右旋美托咪定（dexmedetomidine ,Dex）对患者自主呼吸功能和镇静深度的影响,为Dex临床安全应用提供参考依据。方法 80例患者随机分为四组,Dex 0.5 μg/kg组（D₁组）,1.0 μg/kg组（D₂组）,1.5 μg/kg组（D₃组）和对照组（D₀组）,每组病人20例。麻醉诱导前35min分别静脉泵注Dex或0.9%生理盐水10 mL。记录预先给药前（T0 ）、预处理后5min（T1）、10min（T2）、15min（T3）、20min（T4）、25min（T5）和30min（T6）患者的潮气量（V_T）、分钟通气量（MV）、呼气末二氧化碳分压（P_ETCO₂）、呼吸频率（RR）、第一秒呼出率（FEV₁%）、顺应性环（PV环）、阻力环（FV环）、脉搏氧饱和度（SpO₂）、心率（HR）、平均动脉压（MAP）等呼吸力学参数和循环参数及脑电双频谱指数（BIS）及警觉/镇静评分（OAA/S）,并于T0、T1、T3和T6抽取动脉血行血气分析记录PaO₂、PaCO₂和pH值。结果 与对照组相比,D₁组的V_T、RR、MV、P_ETCO₂、FEV₁%、PaCO₂和SpO₂均无变化（P>0.05）,PV环和FV环形态基本正常;D₂组和D₃组MV分别降低16.9%和27.0%;PaCO₂分别升高11.0%和19.9%;FEV₁%分别下降11.0%和14.9%。四组患者均无发生呼吸暂停,而且所有患者SpO₂均在98%或以上。D₃组自主呼吸的PV环和FV环图形面积明显缩小（P<0.05）。D₁组BIS值均在85以上,OAA/S 4分为65%,镇静满意率低,OAA/S 3分仅20%;D₂组镇静满意率最高,OAA/S 3分达70%,且无出现过度镇静;D₃组有60%患者OAA/S评分小于或等于2。结论 静脉泵注Dex所产生的的镇静效应及其对呼吸力学的影响,随着泵注Dex剂量增大,患者镇静程度加深,虽然SpO₂仍在正常范围,但呼吸会受到一定抑制（PV环和FV环图形面积缩小,PaCO₂ 均上升）,临床推荐静脉泵注Dex剂量为0.5 μg/kg~1 μg/kg以策安全。

Objective The purpose of this study was to observe the dynamic indexes of respiratory mechanics in patients with continuous airway monitoring,and to monitor the Bispectral index （BIS） and the Observer's Assessment of Alertness/Sedation Scale （OAA/S）. We evaluated the effect of dexmedetomidine （Dex） on the autonomic respiratory function and the sedative depth of the patients in a comprehensive and systematic way,so as to provide reference for the clinical safety of Dex. Methods In the study,we randomly divided 80 patients into four groups,Dex 0.5,group g/kg （group D₁）,1 group g/kg （group D₂）,1.5 g/kg group （D₃ group） and control group （D₀ group）. There were 20 cases in each group. At about 35min before anesthesia induction,Dex or 0.9% saline 10 mL was injected intravenously. The following time points were selected： pre- administration （T0）,pre-treated 5min （T1）,pre-treated 10min （T2）,pre-processed 15min （T3）,pre-processed 20min （T4）,pre -treated 25min （T5） and pre-treated 30min. The following experimental parameters were recorded at the above time point： tidal volume （VT）,minute ventilation （MV）,end expiratory carbon dioxide partial pressure （P_ETCO₂）,respiratory frequency （RR）,first second exhalation rate （FEV1%）,compliance ring （PV ring）,resistance ring （FV ring）,pulse oxygen saturation （SpO₂）,heart rate （HR）,and respiratory mechanics parameters and circulatory parameters such as mean arterial pressure （MAP）,bispectral index （BIS） and vigilance / sedation score （OAA/S）. At the same time at T0,T1,T3 and T6,arterial blood gas was extracted,and PaO₂,PaCO₂ and pH values were recorded. Results Compared with the control group,the value of VT,RR,MV,PETCO₂,FEV1%,PaCO₂ and SpO₂ in group D₁ did not change significantly （P>0.05）,and the morphology of PV ring and FV ring were basically normal. In group D₂ and group D₃,MV decreased by 16.9% and 27% respectively;PaCO₂ increased by 11% and 19.9% respectively;FEV1% decreased by 11% and 14.9% respectively. No apnea occurred in the four groups,and all patients had SpO₂ at 98% or above. The area of PV rings and FV rings of spontaneous breathing in group D₃ was reduced （P<0.05）. The BIS values in group D₁ were above 85,OAA/S 4 was 65%,sedative satisfaction rate was low,20% patients had a score of 3 in OAA/S;group D₂ had the highest sedative satisfaction rate,70% of patients had a score of 3 in OAA/S,and no excessive sedation;60% of patients in group D₃ with an OAA/S score that was less than or equal to 2. Conclusion The sedation effect that was caused by intravenous infusion of Dex and its effect on respiratory mechanics are as follows： with the increase of Dex's dose,the degree of sedation is deepened. Although SpO₂ is still in the normal range,the respiration will be restrained （the area of PV ring and FV ring is narrowed,the value of PaCO₂ is increased）,and the clinical recommendation of intravenous infusion Dex is at a dose of 0.5µg /kg~1µg /kg for safety reasons. .
