BACKGROUND AND OBJECTIVE: A randomized controlled trial of patients undergoing laparoscopic cholecystectomy. To evaluate whether the instillation of levobupivacaine, with epinephrine, intraperitoneally, reduces morphine consumption; further, to consider the degree of abdominal and shoulder pain in the presence of local anaesthetic at the site of surgical incision. METHODS: Patients received a standardized procedure and were allocated randomly to receive either (a) 2.5 mg mL(-1) levobupivacaine 30 mL, with epinephrine 5 microg mL(-1), or (b) normal saline 30 mL, with epinephrine 5 microg mL(-1), to the bed of the gall bladder and above the liver, immediately before wound closure. RESULTS: Median (interquartile range) total abdominal pain during inspiration in the levobupivacaine group was significantly (P = 0.041) lower (71 (21-129) mm) than that in the placebo group (123 (71-179) mm). However, there was no significant difference between the two groups with respect to total abdominal pain at rest, right shoulder pain or the consumption of rescue morphine and rescue dihydrocodeine. There were no differences between the two groups with respect to the administration of cyclizine, total nausea and total sedation scores. In addition, the number of episodes of vomiting was not significantly different. CONCLUSIONS: Intraperitoneal administration of levobupivacaine with epinephrine is associated with modest analgesia following laparoscopic cholecystectomy. 相似文献

Rapid assessment of fine needle aspiration smears has become popular. The goal is minimal time required and fastest turn around time for test results in breast aspirates. In the present study, fine needle aspiration smears from 100 cases of breast lump were stained by modified ultrafast Papanicolaou stain which consisted of the following changes from ultrafast Papanicolaou stain: (i) Use of Gill 's haematoxylin instead of Richard Allan haematoxylin, (ii) omission of orange G from cytostain. Wet fixed smears subjeted to May-Gruenwald and Giemsa stain and an air dried smear subjected to modified ultrafast Papanicolaou stain were compared. Smears stained by modified stain showed transparent cells with crisp nuclear features in a blood free background. Total time required in this staining was 130 seconds. Out of 100, diagnosis was inadequate in 5 cases. In 95 cases cytological diagnosis was as follows: 60 benign, 27 ductal malignancy and 8 of inflammatory lesions. There was 100% agreement in cytologic diagnosis offered on smears stained by May-Gruenwald and Giemsa and modified ultrafast Papanicolaou stain. 相似文献

OBJECTIVE: Clear amniotic fluid is frequently considered a reassuring sign during labor. Our aim was to examine the incidence of meconium that can only have been passed intrapartum and to determine its neonatal associations and whether its absence is a useful sign. METHODS: This was a prospective cohort study of 8394 "low risk" laboring women at term with clear amniotic fluid at early amniotomy. RESULTS: Meconium was passed in 5.2% of labors but was not detected until delivery of the fetal head in 51.5% of these. It was associated with moderate-severe acidosis (odds ratio [OR] 4.40; 95% confidence interval [CI] 3.21, 6.03), low Apgar score at 5 minutes (OR 6.49; 95% CI 2.73, 15.44), and neonatal seizures (OR 4.33; 95% CI 3.17, 5.93). However, the sensitivity for these outcomes of the intrapartum passage of meconium and, particularly, its detection before delivery was very poor. CONCLUSION: Although correlated with adverse neonatal outcomes, most affected infants had clear amniotic fluid throughout labor. The presence of clear amniotic fluid is an unreliable sign of fetal well-being. 相似文献

Chronic illnesses in children and adolescents have devastating influence on them and their families. The patients have to
cope up with illness, medication and it’s influence on their development. Consequently a large number of them have emotional
disorders which influence the course and outcome of physical disorder. In recent few years, research has shifted its focus
from merely figuring out the prevalence of the emotional disorders to understanding the adjustment to chronic illness under
defined theoretical constructs. Apart from temperamental variation, family burden and functioning have been identified as
factors operating in determining adjustment. Distress experienced by the family and disturbed family functioning directly
influences the emotional outcome in physically disordered children. Comprehensive coordinated care services are required for
integration of these patients into the community. 相似文献

A case of double aneuploidy involving chromosome 21 and Y is reported in an eight-month-old infant with developmental delay and failure to thrive. Patient had all classical phenotypical features of trisomy 21 except, absence of epicanthal folds. The diagnosis was confirmed by cytogenetic study performed on peripheral blood leucocyte culture using G-banding. Literature review revealed only 17 cases of XYY and trisomy 21 reported so far. No such case is reported in Indian literature. Relevant literature is reviewed and possible effects of trisomy 21 on XYY and that of XYY on trisomy 21 has been discussed. A routine chromosomal study even in patient with classical features of Down syndrome has been advocated. Interestingly, our patient also had left to right shunts at atrial and ductal level and tricuspid regurgitation. Given the rarity of the disorder and scanty published data the incidence, phenotype and recurrence risk are difficult to establish. 相似文献

Plasma homocysteine levels in Indian patients with essential hypertension and their siblings 总被引:3,自引:0,他引:3
BACKGROUND: An association between plasma homocysteine and essential hypertension and their non-hypertensive siblings is controversial. METHODS AND RESULTS: Plasma homocysteine levels were measured in subjects with essential hypertension (n = 50), their normotensive siblings (n = 50) and normotensive controls (n = 50). All the subjects were non-diabetic, had no past history of myocardial infarction, stroke or peripheral vascular disease and had normal renal functions. The mean homocysteine values were 18.96 +/- 8.08 micromol/L in patients, 14.84 +/- 5.55 micromol/L in siblings and 10.50 +/- 4.92 micromol/L in controls. Plasma homocysteine level were found to be significantly higher in patients with hypertension (p < 0.0001) and their normotensive siblings (p < 0.0001) when compared to controls. Also patients with hypertension had their higher plasma homocysteine levels compared to their siblings (p < 0.0036). CONCLUSION: Plasma homocysteine levels are significantly elevated in Indian patients with essential hypertension and their normotensive siblings. Thus, plasma homocysteine may serve as a marker for the development of essential hypertension. 相似文献

The presence of high concentration of metals (Cr, Cd, Co, Ni, Pb, etc.) in the work place environments of various types of industries including electroplating units are well known to influence respiratory system. Pulmonary function tests including forced expiratory capacity (FVC), volumes, mechanics and slow vital capacity (SVC) were studied in 80 males, divided into group I and Group II of 40 each were drawn from electroplating and non-electroplating units, respectively from East Delhi factories. The lung function tests were measured using computerized Spiro-232 of P.K. Morgan, Values of majority of lung function parameters such as FEV1/FVC%, FEF50 FEF75, PIFR, FIF50, MVV and SVC were decreased in electroplaters, perhaps due to the exposure to metals and their lower anthropmetric results as compared with non electoplaters. Where as results of TLC, FRC, RV & RV/ TLC% were higher in electroplaters and this may be attributed to higher values of RV in them as compared with non electroplaters. 相似文献
