Methods A quasi-randomized controlled trial was used. A total of 62 paraquat-poisoned patients (from January 2009 to March 2010) were divided into experimental group and control group in order to compare the healing rate of oral ulcer, complications and the necessity of early oral care between the two groups. Results The oral mucosa lesions in experimental group obviously alleviated and the complications decreased. The effective early oral care provided the very favorable conditions for better prognosis. Conclusion The early oral care for paraquat-poisoned patients could relieve the pain of oral ulcer, reduce the complications and improve patient′s life quality.
Objective To explore the clinical value, latest research progress, and clinical controversy of total neoadjuvant therapy (TNT) in locally advanced rectal cancer (LARC). Method We searched and reviewed on the latest literatures about studies of the clinical research of TNT in LARC. Results TNT could make the tumor downstage rapidly and improve the patients’ treatment compliance. In terms of organ preservation rate, 3-year disease-free survival and pathological complete remission rate, TNT had advantages and was a especial potential treatment strategy compared with traditional methods. Conclusions TNT decreases local recurrence rate and improves the long-term survival. For LARC patients with strong desire for organ preservation, TNT is a good treatment choice and has the value of clinical promotion.
Objective To summarize the clinical application of esophagogastrostomy with layered anastomosis and to observe the healing quality of anastomotic stoma in animal experiments. Methods One thousand and twenty-four patients suffered from carcinoma of esophagus or carcinoma of gastric cardia had undergone esophagogastrostomy by layered anastomosis with absorbable suture. Twenty-four experimental dogs (adult male healthy hybrid dogs) were divided into two groups: the experimental group and the control group. The former (experimental group) underwent the layered anastomosis, the diameter of esophagogastric stoma and the length and depth of stomal scar were measured under anesthesia in both groups on 5th,8th,14th,and 42th postoperative day, respectively. So were done the histological measurement, such as the count infiltrating inflammatory cells, the proliferation of blood capillary and other cells. And the cytokines related to wound healing (LsAB technique) such as epidermal growth factor(EGF), transforming growth factor-beta 1 (TGF-beta 1) were detected, either. Results One thousand and twenty-four patients had no anastomotic leakage. There were only 6 patients suffered from mild anastomotic stricture, and they got well after one dilatation. The results of the measurement of 24 experimental dogs revealed that, in the experimental group, the mucosa was in good connecting condition, had a soften anastomotic stoma and a thin scar. The counts of inflammatory cells and fibroblast showed more in number at the early time after operation (Plt;0.05), while showed less in number at the advanced time of operation (Plt;0.05). In the control group, however, the mucosa were in a bad connecting condition, the scar was thicker, and the muscle layer was frequently exposed. The counts of inflammatory cells and fibroblast were fewer at the early time after operation, however, they had a clearly tendency of increasing at the anaphase after the operation. On the cytokines related to the healing of wound in the experimental group, there was a high expression and activity at the early period. There were a little expression up to postoperative 42 d. Whereas, in the control group, there had a low expression level,increased clearly on postoperative 8 d, and still a higher expression up to postoperative 42 d. Conclusions The esophagogastrostomy by layered anastomosis has a high healing quality with a thin scar. The proliferation of cells and the expression of growth factors benefits the normal healing of wound by first intention.
ObjectiveTo explore the effect of goal directed analgesia on patients with noninvasive positive pressure ventilation (NPPV) in the intensive care unit (ICU).MethodsThis was a retrospective study. Two hundred sixty-four patients requiring non-invasive positive pressure ventilation were enrolled in the ICU of this hospital, including 118 patients in the empirical analgesia group and 146 in the goal directed analgesia group. The empirical analgesia group was treated with remifentanil to analgesia and propofol, midazolam or dexmedetomidine to sedation. The sedative depth maintained <1 measured by the score of the Richmond restless sedative scale (RASS). The same analgesic and sedative drug were first used in the goal directed analgesia group to maintain the Critical Care Pain Observation Tool score <2, and the RASS score <1 was maintained after the analgesia depth were achieved. Whether the patients occurred delirium was assessed by the Confusion Assessment Method for the ICU. The dosage of analgesic and sedative drugs, the dependability (based on the total ventilation time in the first 24 hours after ventilation), the incidence of delirium, the rate of invasive ventilation, the total time of NPPV and the length of stay of ICU were observed in the two groups.ResultsThere were no significant differences in age, sex, APACHEⅡ score, mean arterial pressure, heart rate, respiratory rate, SpO2, arterial blood gas and the reason of NPPV between the two groups. The dosage of analgesic and sedative drugs in the goal directed analgesia group were less than the empirical analgesia group, and the dependability was higher than that of the empirical analgesia group ［(12.6±5.8)h vs. (10.9±4.8)h, P<0.05), and the incidence of delirium and the rate of invasive ventilation were also lower than those of the empirical analgesia group (15.8% vs. 25.4%, P<0.05; 32.9% vs. 44.9%, P<0.05). The total time of NPPV in the goal directed analgesia group was shorter than that of the empirical analgesia group ［(28.6±8.8)h vs. (37.3±10.7)h, P<0.05), but there was no significant difference in the length of stay in ICU.ConclusionGoal directed analgesia can improve the dependability of NPPV patients, reduce the use of sedative drugs, and decrease the incidence of delirium and rate of invasive ventilation.
