ObjectiveTo examine the effect of initiating very early feeding on time-to-reach full feeding in stable, small for gestational age (SGA) preterm infants.MethodPreterm infants with gestational age below 37 weeks and birth weight below the 10th percentile were randomly allocated to a very early (within 24 hours of birth) feeding regimen or delayed (after 24 hours of birth) feeding. All infants had in utero evidence of absent or reverse diastolic flow. Infants unable to start early feeding were excluded. Time-to-reach full feeding, feeding progression, and related morbidity were compared. Electrogastrography (EGG) was used to measure pre- and postprandial gastric motility on the second and seventh day after feeding initiation.ResultsSixty infants were included in the study, 30 in each group. Infants included in the very early feeding regimen achieved full enteral feeding sooner than controls (98 ± 80-157 vs. 172 ± 123-261 hours of age, respectively; p = 0.004) and were discharged home earlier (p = 0.04). No necrotizing enterocolitis (NEC) was documented in both study groups. Gastric motility was improved at day seven after feeding initiation in both study groups, with no difference between groups.ConclusionsStable SGA preterm infants on a very early feeding regimen achieved full enteral feeding and were discharged home significantly earlier than those on a delayed regimen, with no excess morbidity.  相似文献

AIM:To investigate the influence of percutaneous local therapy on gastric myoelectrical activity in patients with hepatocellular carcinomas.METHODS:Forty-four patients with hepatocellular carcinoma(HCC) [27 males and 17 females,ranging in age from 49 to 81 years old(69.7 ± 8.01 years)] who were admitted for percutaneous local therapy were enrolled in this study.We examined clinical abdominal symptoms using the Gastrointestinal Symptom Rating Scale(GSRS) before and 3 d after percutaneous local therapy.We also measured cutaneous fasting and postprandial electrogastrography(EGG) recordings before and 3 d after percutaneous local therapy.RESULTS:We found that the percentage of normogastria in the fasting period was lower in the Child B group than in the Child A group(66.8% ± 8.6% vs 84.0% ± 3.8%).After percutaneous local therapy for HCC,the percentages of normogastria in the fasting period were significantly decreased(81.6% ± 3.5% vs 75.2% ± 4.5%).None of the postprandial EGG parameters changed significantly after percutaneous local therapy for HCC.Percutaneous local therapy for HCC reduced the power ratio(PR).In particular,the PR of tachygastria was significantly decreased after therapy(P < 0.01).However,no significant differences were found in the postprandial EGG parameters.Likewise,no significant differences were found in the calculated GSRS scores obtained from the questionnaire before and after therapy.CONCLUSION:Gastric slow-wave dysrhythmias were induced by percutaneous local therapy in HCC patients,even though the GSRS scores obtained from the questionnaire did not change significantly.  相似文献

Objective  To examine gastric myoelectrical activity in patients with primary biliary cirrhosis (PBC). Materials and methods  The study comprised 11 female PBC patients (average age 53.4 years, range 43–70) and two aged-matched control groups: 11 (53.4 years, range 37–78) healthy women, and 10 female patients with chronic hepatitis C, CHC (53.9 years, range 35–66), who were examined prior to administration of an antiviral therapy. Every subject underwent an electrogastrographic recording comprising a 30-min interdigestive and a 120-min postprandial period. Results  Abnormal electrogastrograms, containing prolonged epochs of tachygastria in the postprandial phase were found in 2 out of 11 (18.2%) patients having both stage IV of the Scheuer’s PBC classification, as well as in 1 patient out of 10 (10%) with CHC at stage F2 according to the METAVIR fibrosis score. Conclusion  Electrogastrographic abnormalities do not seem to be pathognomonic for the PBC as a disease, but rather would be considered an unspecific sequel of a morbid liver affection.  相似文献

窒息后新生儿胃电活动的研究   总被引:5,自引:0,他引:5  
目的 利用胃电图探讨窒息对新生儿胃电活动的影响。 方法 采用瑞典 CTd-synec-tics公司生产的便携式胃电图 ( EGG)记录仪对 50例窒息后新生儿和 2 0例正常新生儿进行了喂奶前、后各 3 0 min的胃电活动的检测 ,利用计算机 EGG Version6.4 0软件分析系统分析数据。 结果  70例新生儿有 3 9例 ( 56% )成功记录到 EGG。轻度窒息组与对照组比较 ,喂奶前胃动过缓 ( <2cpm)百分比增多 ( 7.0± 6.8与 4 .7± 5.4 ) ,差异有非常显著意义 ( P<0 .0 1 )。重度窒息组与对照组及轻度窒息组比较 :喂奶前、后正常慢波百分比明显降低 ( P<0 .0 1 ) ,胃动过速 ( >4 cpm)百分比明显增多 ( P<0 .0 1 )。主功频率不稳定系数 ( DFIC)增高 ( P<0 .0 1 )。 结论 EGG可以用来研究窒息后新生儿的胃电活动 ,进而研究新生儿消化道动力 ;围产期轻度窒息新生儿喂奶前胃动过缓增多 ,重度窒息新生儿喂奶前、后正常慢波百分比明显降低 ,胃动过速百分比明显增多 ,提示围产期窒息的新生儿出现拒乳、腹胀、呕吐等症状 ,可能与其胃电节律异常有关。  相似文献

目的探讨幽门螺杆菌(Hp)对非溃疡性消化不良(NUD)患者体表胃电图的影响.方法通过胃镜活检胃窦粘膜进行快速尿素酶试验及Giemsa检查以判定Hp感染状态,并对NUD患者空腹体表胃电图与Hp二者的关系进行了评价.结果35例NUD患者Hp阳性(Hp+)24例、Hp阴性(Hp-)11例,Hp+NUD患者AP值明显高于Hp-NUD患者及健康人(胃体269.61±81.11μv、148.10±61.32μv、156.75±71.73μv;胃窦272.94±68.45μv、150.41±71.11μv、193.50±98.74μv,P<0.01);而FP值前者显著低于后两者(胃体1.77±0.36cpm、2.80±0.77cpm、2.93±0.38cpm;胃窦1.80±0.49cpm、2.85±0.63cpm、2.98±0.28cpm,P<0.01);正常慢波百分比值,前者也明显降低(胃体41.07±12.67%、59.57±19.41%、68.49±1.95%;胃窦31.84±15.67%、60.58±21.59%、19.19±4.34%,P<0.01);并且Hp+NUD患者胃电节律紊乱发生率亦显著多于后两者(胃体37.5%、18.2%、11.1%;胃窦45.8%、18.2%、0,P<0.01).结论Hp+NUD患者胃电节律紊乱发生率明显高于Hp-NUD患者及健康人,Hp感染可能导致正常慢波的紊乱.  相似文献

目的分析不同胎龄新生儿体表胃电图的临床特点。方法收集不同胎龄新生儿的体表胃电图资料。将收入我科不同胎龄的新生儿分为4组:Ⅰ组为胎龄≥37周;Ⅱ组为胎龄34~36^+6周;Ⅲ组为胎龄32~33^+6周;Ⅳ组为胎龄〈32周,在生后1周内进行体表胃电图检测,记录并分析胃电图参数。应用ANOVA方法对各组间的差异进行统计学分析。对其中部分早产儿在生后1周内、2、4周分别进行胃电图检测,应用配对t检验检测同一病例的胃电图参数的前后差异。结果对141例新生儿进行了胃电图检测,Ⅰ组25例;Ⅱ44例;HI组33例;Ⅳ组39例。与成人和儿童相比所有新生儿的正常胃电慢波百分比均较低,平均为30.6%,而胃电节律紊乱百分比较高。各组间正常胃电慢波百分比、胃电节律过缓百分比及胃电节律过速百分比差异无统计学意义。24例早产儿生后4周及生后2周的胃电图参数与生后1周内相比差异无统计学意义。结论与成人和儿童相比,新生儿的胃肌电活动不成熟,生后1周内不同胎龄的早产儿与足月儿的胃电形式比较,差异无统计学意义,新生儿的胃肌电活动在生后4周时仍处于发育成熟阶段。  相似文献

The modified adaptive filter method described in Part 1 was applied to 16 stretches of (cutaneous) electrogastrographic signal of 17·07 min duration. A signal-to-noise ratio improvement of about 8 dB was achieved. The most characteristic feature of the filter method appeared to be that wave-form and phase of the gastric component of the electrogastrographic signal are preserved. It is concluded that the use of the modified adaptive filter forms a valuable tool in the study of the electrogastrographic signal.  相似文献

目的通过胃电图(EGG)检查,观察32例甲状腺机能亢进(甲亢)病人,29名甲状腺机能减退(甲减)病人及30名正常健康人餐前和餐后30min的体表胃电频谱变化。结果3组内餐后胃电图主频(DF)、平均幅值(AP)、正常慢波百分比(N%)与餐前相比均有显著增加(P<0.01)。甲亢组主频和平均幅值与对照组相比,无显著差异(P>0.05),甲减组平均幅值与正常慢波百分比较对照组差异显著(P<0.01)。结论甲亢组食欲亢进在胃电图上无特殊反映,表现为主频正常,胃电节律正常,振幅亦无明显升高。甲减组食欲减退可能与胃动过缓,胃电节律紊乱增多有关。  相似文献

目的探讨腹部手术后胃肠运动功能障碍的机理。方法对22例胆囊切除患者行手术前后胃电图描记,并对其中17例行术后胃窦、十二指肠和空肠测压。结果术后当天胃电正常波所占百分比、术后胃电幅度均较术前有显著意义的降低(P<001);术后胃窦部移行性运动复合波(MMC)Ⅲ期最早出现于十二指肠,胃窦出现最晚,次数最少;术后胃窦MMCⅢ期平均压力和收缩曲线面积明显小于十二指肠和空肠,差异有显著意义(P<005)。结论腹部手术后胃肠运动功能障碍与胃电幅度降低密切相关;术后胃窦部MMCⅢ期恢复明显落后于十二指肠和空肠,这是胃排空障碍的重要原因。  相似文献
