腹部重症脓毒症老年患者术后T淋巴细胞亚群的变化

目的探讨重症脓毒症患者免疫治疗及各免疫指标的变化对严重脓毒症患者预后的影响。方法将20例腹部无明显感染的患者、20例腹部脓毒症患者不伴器官功能障碍、18例腹部严重脓毒症及脓毒性休克患者分为A、B、C组,A组术前及A、B、C组术后第1、3、7天,各抽取外周静脉血5ml于肝素管内,分别测定T淋巴细胞亚群(CD3、CD4、CD8、CD4/CD8)。同时记录生命体征的变化和预后转归。结果A、B、C三组在术后1、3天,CD3、CD4、CD4/CD8均下降,C组下降明显,与A、B组比较,差异具有显著性意义(P<0.05),术后第7天A、B、C组(病情好转者)均上升,C组恶化者CD3、CD4、CD4/CD8持续低下,与A、B、C组(病情好转者)比较,差异具有显著性意义(P<0.05)。结论手术对T淋巴细胞CD3、CD4抑制明显,术后1、3天抑制明显,7天明显上升至正常。对于术后脓毒症不伴器官功能障碍者对T淋巴细胞亚群影响不大,其变化与手术对机体免疫功能的变化一致。对于术后重症脓毒症及脓毒性休克患者IgA、IgM、IgG,C3、C4及T淋巴细胞亚群CD3、CD4、CD4/CD8明显降低,且随病情恶化,持续在较低水平。

小切口加脊柱花刀治疗髓核骨化性腰椎间盘突出症

为保留腰椎后部结构的完整性，防止术后腰椎不稳，采用小切口单侧小开窗加脊柱花刀治疗旁侧型髓核骨化性腰椎间盘突出症22例，单侧扩大开窗加脊柱花刀治疗中央型髓核骨化性腰椎间盘突出症10例。手术尽可能地保留了腰椎全部结构的完整性，可防止术后腰椎不稳和减少对硬膜和神经根的疤痕粘连。并就32例髓核骨化性腰椎间盘突出症患者CT图像中髓核骨化的形式和形态进行了讨论。     

Neonatal necrotizing enterocolitis

PURPOSE: A retrospective, 12-year review of neonatal necrotizing enterocolitis was undertaken at a county hospital, with emphasis on presentation signs and symptoms. METHODS: Eighty-two patients with presence of intramural air were included in the study. The following signs and symptoms were studied: evidence of respiratory distress, use of umbilical catheters, white blood cell count and temperature at presentation, time interval from birth to diagnosis and time interval from diagnosis to operative intervention, presence of intramural air, air in biliary tree or free air, changes in abdominal girth, and presence of occult or gross blood in stools. Comparison was done among infants who had surgical or medical treatment, premature and full-term infants, and infants who had neonatal necrotizing enterocolitis less than or more than 20 days after birth. RESULTS: Eleven patients had a fatal outcome, with an overall survival of 87 percent. Sixty-four patients were treated medically and 18 had operative treatment. Mortality of the surgically treated group was 44 percent. Neonates who had surgical intervention had a left shift of the white blood cell count more commonly present, and all had documented abdominal distention. There were 62 premature and 20 full-term neonates in the group. Full-term neonates developed neonatal necrotizing enterocolitis earlier after birth (5.3 days compared with 15.3 days in the premature neonate group). Full-term neonates had a better prognosis in our series. Presentation of symptoms more than 20 days after birth did not change outcome. CONCLUSION: Our results reflect the experience of a community-based hospital. Clinical acumen remains the cornerstone of diagnosis and management.     

64例脾脏损伤手术的临床分析

正常腹内压影响因素的临床研究

目的　探讨正常腹内压的影响因素 ,建立腹内压回归方程。方法　应用膀胱测压法测定 10 6例住院患者的腹内压 ,并对年龄、性别、身高、体重、体质指数、既往和近期腹部手术史、住院原因、合并症情况及数量等 14项因子与腹内压的关系进行分析。结果　住院患者平均腹内压为 5 .5mmHg( 1mmHg =0 .133kPa) ,范围为 0 .4～12 .8mmHg。各级体质指数相应的腹内压差异有显著性意义 (F =5 .5 5 0 ,P<0 .0 1)。男性腹内压比女性高 2 .0mmHg ,差异有显著性意义 (t=3.12 2 ,P<0 .0 1)。其他 12种因素对腹内压无明显影响 (P>0 .0 5 )。结论　正常腹内压可能受性别和体质指数影响 ,存在明显的个体差异     

单侧听力耳鼓室成形术的临床探讨

目的分析单侧听耳患者的鼓室成形术,了解手术方法和手术疗效。方法对9耳慢性化脓性中耳炎胆脂瘤型进行了乳突根治术加鼓室成形术,对37耳慢性化脓性中耳炎单纯型和中耳炎后遗症进行鼓室成形术,并比较术后效果。手术后3个月~1年之间进行术后听力评价。结果46耳单侧听力耳术前言语频率气导平均听阈为60.2±23.1dB HL,骨导听阈35.7±17.0dB HL;手术后的平均气导听阈为51.3±22.6dB HL,骨导听阈为36.3±10.6dB HL。鼓室成形术后疗效评定:37耳外耳道宽敞,人工鼓膜完整,血运好,近正常鼓膜色泽;纯音测听500~2000Hz平均气导听力改善23例(62.16%,23/37),听力不变13例(35.14%,13/37),听力恶化(下降10dB以上)1例(2.70%,1/37)。乳突根治术加鼓室成形术后疗效评定:9耳术腔干洁,人工鼓膜完整,血运好,近正常鼓膜色;纯音测听500~2000Hz平均气导听力改善5例(56.56%,5/9),听力不变4例(44.44%,4/9)。结论各型慢性化脓性中耳炎都可作为单侧听力耳的手术适应症。手术时只要注意手术技巧,认真仔细,一般不会造成手术后骨导听力的下降。术后干耳和保持原有听力是手术的最终目的。     

肛周按揉及温水足浴对腹部手术后患者肛门排气时间的影响

目的探讨肛周按揉及温水足浴对腹部手术后患者肛门排气时间的影响。方法选择普外科180例腹部手术后患者，随机分为A组（肛周按揉＋温水足浴组＋常规护理）90例和B组（常规护理组）90例。比较2组肛门排气时间及腹胀情况。结果首次肛门排气时间A组早于B组，2组比较差异有统计学意义（P＜0．01）；腹胀症状A组较B组轻。结论肛周按揉结合温水足浴可显著缩短腹部手术术后患者肛门排气时间，减轻术后腹胀症状。     

腹茧症合并不孕七例临床分析

目的探讨腹茧症合并不孕的病因和诊治方法。方法对1996年至2005年因不孕施行腹部手术中发现的7例腹茧症患者进行回顾性分析。结果7例患者均为原发、管性不孕。其共同特点为,术中见多重疏松、灰白色的纤维膜状组织包裹于肠管间隙及盆腔脏器,手术分离困难。结论腹茧症引起的不孕可能为纤维膜包裹输卵管,使其丧失活动度,伞端封闭,无法完成捡拾和输送卵子的功能或包裹卵巢,使其排卵障碍而不能受孕。术后"假性囊肿"或"包裹性积液"易复发。     

Motor blockade associated with continuous epidural infusion after abdominal hysterectomy: a randomized controlled trial comparing 0.1% ropivacaine-plus-fentanyl versus 0.2% ropivacaine-alone

We compared rates of motor blockade, analgesia, adverse effects and patient satisfaction of 0.1% ropivacaine+fentanyl versus 0.2% ropivacaine-alone in a randomized, controlled trial. Fifty-four women who had undergone abdominal hysterectomy were randomly allocated into two groups to receive an epidural block at L_1–2 or L_2–3: group R received 0.2% ropivacaine-alone and group RF received 0.1% ropivacaine plus 2 μg fentanyl/ml, both at 8 ml/h. Rescue analgesia was provided via a morphine-loaded PCA device. Motor blockade (using a modified Bromage scale), pain intensity (visual analogue scale (VAS)), morphine consumption, level of sensory blockade and adverse effects, were measured at 4, 8 and 21 h after infusion. Patient satisfaction with pain management was assessed at the end of the study. The rates of motor blockade were not different at 8 h after infusion but at 21 h, group RF had significantly less motor blockade than group R. There were no differences in VAS, level of sensory blockade, adverse effects and patient satisfaction. Morphine consumption at each measurement was comparable but the total amount used by group RF was less than group R (12 mg versus 20 mg, P=0.049). Therefore, 0.1% ropivacaine with fentanyl 2 μg/ml appears to offer advantages over 0.2% ropivacaine-alone.
