IV lidocaine is effective in suppressing the cough reflex of tracheal intubation, extubation, bronchography, bronchoscopy, and laryngoscopy. We investigated this effect of lidocaine on fentanyl-induced cough in 502 patients of ASA physical status I and II scheduled for elective surgery. The patients were assigned to 2 equal groups to receive either lidocaine 1.5 mg/kg or placebo (0.9% saline) over 5 s 1 min before the administration of fentanyl 3 mug/kg in a randomized and double-blind fashion. Coughs were classified as coughing and graded as mild (1-2), moderate (3-4), or severe (5 or more). The results of the study suggest that IV lidocaine 1.5 mg/kg, when administered 1 min before fentanyl, is significantly effective in suppressing fentanyl-induced cough compared to placebo (0.9% saline) (218 versus 165 patients) (P < 0.002) but without affecting the severity of cough (P > 0.05). 相似文献

Acceptance of the value of antibiotic prophylaxis in gastroduodenal surgery is growing, but only one controlled, double-blind study justifying this is available. In this second, controlled, randomized, double-blind study 60 patients underwent urgent and elective gastroduodenal operations. Among 32 patients receiving cefamandole perioperatively for prophylaxis, only 1 subsequently had a wound infection, but wound infections occurred in 8 of the 28 patients who received a placebo (P less than 0.01). Infection rates were higher in contaminated wounds and in urgent operations than in clean-contaminated wounds and elective surgery. The results confirm the value of antibiotic prophylaxis in this setting. 相似文献

BACKGROUND AND OBJECTIVES: Sciatica is a neuropathic pain syndrome caused by compression and/or inflammation of spinal nerve roots by herniated disc material, and its treatment is therefore usually aimed at reducing compression and inflammation. Studies have shown that both systemic local anesthetics and N-methyl-D-aspartate (NMDA) receptor antagonists may produce analgesia in a variety of neuropathic pain syndromes. The present study evaluated the analgesic efficacy of i.v. infusions of the local anesthetic lidocaine, the NMDA receptor antagonist amantadine, and a placebo in sciatica. METHODS: Thirty patients with sciatica, as confirmed by physical examination and imaging studies, were enrolled in a randomized, double-blind, three-arm crossover trial. Infusions of amantadine (2.5 mg/kg), lidocaine (5 mg/kg), and a placebo were administered over a 2-hour period, 2-7 days apart from each other. Spontaneous pain (visual analog scale) and evoked pain (straight leg raise) were measured every 30 minutes for 3 hours. RESULTS: Lidocaine reduced spontaneous pain as compared with amantadine and with the placebo for all measurements and at a significant level at the 30 (P < .05), 120, and 180 (P < .01) minute time points. Maximal pain reduction from the baseline was 62 +/- 7% for lidocaine, 43 +/- 7% for amantadine, and 47 +/- 7% for the placebo. Straight leg raise test also significantly improved with lidocaine (from 30 to 37 degrees; P < .05), as compared to amantadine (34-36 degrees) and to the placebo (32-34 degrees). All three treatments were relatively well tolerated. CONCLUSIONS: Intravenous lidocaine, rather than amantadine, reduces both spontaneous and evoked sciatic pain. 相似文献

OBJECTIVE: To investigate the effect of recombinant human erythropoietin (r-HuEPO) administration on perioperative hemoglobin concentrations and on the number of blood transfusions in patients undergoing surgery for gastrointestinal tract malignancies. SUMMARY BACKGROUND DATA: Erythropoietin has been shown to improve the yield of autologously predonated blood and to reduce the subsequent requirements for homologous blood transfusions in cancer patients. METHODS: In this double-blind placebo-controlled study, 31 cancer patients received subcutaneous r-HuEPO in a dose of 300 IU/kg body weight plus 100 mg iron intravenously (study group) and 32 patients received placebo medication and iron (control group). All patients received the medications daily for at least 7 days before and 7 days after the operation. RESULTS: Patients who received erythropoietin received significantly fewer transfusions intraoperatively and postoperatively. Postoperatively, the study group had significantly higher hematocrit, hemoglobin, and reticulocyte count values compared to the control group. The use of erythropoietin was also associated with a reduced number of postoperative complications and improved 1-year survival. CONCLUSIONS: Patients with gastrointestinal tract cancer and mild anemia benefit from perioperative erythropoietin administration in terms of stimulated erythropoiesis, reduction in the number of blood transfusions, and a favorable outcome. 相似文献

BACKGROUND: Many different doses and administration schemes have been proposed for the use of the antifibrinolytic drug tranexamic acid during cardiac surgery. This study evaluated the effects of the treatment using tranexamic acid during the intraoperative period only and compared the results with the effects of the treatment continued into the postoperative period. METHODS: Patients undergoing elective cardiac surgery with use of cardiopulmonary bypass (N = 510) were treated intraoperatively with tranexamic acid and then were randomized in a double-blind fashion to one of three postoperative treatment groups: group A: 169 patients, infusion of saline for 12 h; group B: 171 patients, infusion of tranexamic acid, 1 mg x kg(-1) x h(-1) for 12 h; group C: 170 patients, infusion of tranexamic acid, 2 mg x kg(-1) x h(-1) for 12 h. Bleeding was considered to be a primary outcome variable. Hematologic data, allogeneic transfusions, thrombotic complications, intubation time, and intensive care unit and hospital stay duration also were evaluated. RESULTS: No differences were found among groups regarding postoperative bleeding and outcomes; however, the group treated with 1 mg x kg(-1) x h(-1) tranexamic acid required more units of packed red blood cells because of a significantly lower basal value of hematocrit, as shown by multivariate analysis. CONCLUSIONS: Prolongation of treatment with tranexamic acid after cardiac surgery is not advantageous with respect to intraoperative administration alone in reducing bleeding and number of allogeneic transfusions. Although the prevalence of postoperative complications was similar among groups, there is an increased risk of procoagulant response because of antifibrinolytic treatment. Therefore, the use of tranexamic acid during the postoperative period should be limited to patients with excessive bleeding as a result of primary fibrinolysis. 相似文献

We studied 90 adults undergoing surgical removal of at least both lower
third molar teeth as day cases under standardized general anaesthesia.
Patients were allocated randomly (with stratification for surgeon) to
receive tenoxicam 40 mg, tenoxicam 20 mg or placebo i.v. at induction of
anaesthesia and orally (effervescent tablets) with food on each of the
subsequent 2 days. Panadeine (paracetamol 500 mg-codeine 8 mg) was given
before operation and was available as needed for pain thereafter, to a
limit of two tablets every 4 h. Nefopam i.v. was also available. Efficacy
variables and adverse reactions were assessed over 6 days. Over the 6-day
period, patients who received tenoxicam reported less pain on rest (area
under the curve; P < 0.05) and less disturbance in sleep (P < 0.01)
even though they used fewer Panadeine tablets (P < 0.05). Differences
between tenoxicam 40 mg and 20 mg were not significant. There was no
significant difference in nefopam requirements or side effects, and no
adverse event attributable to the study medication.

OBJECTIVE: To assess the efficacy of glutamine (Gln) dipeptide-enriched total parenteral nutrition (TPN) on selected metabolic, immunologic, and clinical variables in surgical patients. SUMMARY BACKGROUND DATA: Depletion of Gln stores might lead to severe clinical complications. Recent studies indicate that the parenteral provision of Gln or Gln-containing dipeptides improves nitrogen balance, maintains the intracellular Gln pool, preserves intestinal permeability and absorption, and shortens hospital stay. METHODS: Twenty-eight patients (age range, 42-86 years, mean 68 years) undergoing elective abdominal surgery were allocated, after randomization, to two groups to receive isonitrogenous (0.24 g nitrogen kg(-1) day(-1)) and isoenergetic (29 kcal/122 kJ kg(-1) day(-1)) TPN over 5 days. Controls received 1.5 g of amino acids kg(-1) day(-1), and the test group received 1.2 g of amino acids and 0.3 g of L-alanyl-L-glutamine (Ala-Gln) kg(-1) day(-1). Venous heparinized blood samples were obtained before surgery and on days 1, 3, and 6 after surgery for routine clinical chemistry and for the measurement of plasma free amino acids. Lymphocytes were counted and the generation of cysteinyl-leukotrienes from polymorphonuclear neutrophil granulocytes was analyzed before surgery and on days 1 and 6 after surgery. Nitrogen balances were calculated postoperatively on days 2, 3, 4, and 5. RESULTS: No side effects or complaints were noted. Patients receiving Gln dipeptide revealed improved nitrogen balances (cumulative balance over 5 days: -7.9 +/- 3.6 vs. -23.0 +/- 2.6 g nitrogen), improved lymphocyte recovery on day 6 (2.41 +/- 0.27 vs. 1.52 +/- 0.17 lymphocytes/nL) and improved generation of cysteinyl-leukotrienes from polymorphonuclear neutrophil granulocytes (25.7 +/- 4.89 vs. 5.03 +/- 3.11 ng/mL). Postoperative hospital stay was 6.2 days shorter in the dipeptide-supplemented group. CONCLUSION: We confirm the beneficial effects of Gln dipeptide-supplemented TPN on nitrogen economy, maintenance of plasma Gln concentration, lymphocyte recovery, cysteinyl-leukotriene generation, and shortened hospital stay in surgical patients. 相似文献

Background
The preemptive intravenous and intraperitoneal application of local anesthetics is known to improve the postoperative outcome in abdominal surgery. The aim of this study was to compare the analgesic effect of intravenous lidocaine injection to that of intraperitoneal lidocaine instillation in patients who were undergoing laparoscopic appendectomy (LA). 相似文献14.
Various strategies have been studied to reduce the discomfort of rocuronium pain. These studies have shown fentanyl and lidocaine
to be effective in reducing the incidence of pain on rocuronium injection. This prospective, randomized, and double-blind
study was carried out on 80 neurosurgical patients for whom pain on rocuronium injection was assessed after pretreatment with
lidocaine, fentanyl, sufentanil, or normal saline. The 80 neurosurgical patients were randomly allocated to anyone of the
groups to receive lidocaine, fentanyl, sufentanil, or normal saline prior to being given rocuronium. The patients were asked
about any discomfort in the hand, and also to rank that discomfort on a 5-point scale. In the normal saline group, the incidence
of pain was 95%, of which 90% had very severe pain. In the lidocaine group, only 10% of patients reported pain, which was
mild in nature. In the fentanyl group, 95% of patients had pain, of whom 25% had severe to very severe pain. In the sufentanil
group, 85% of patients reported pain, of whom 25% fell into the severe to very severe group. We found that lidocaine was best
at decreasing the incidence of pain on intravenous (i.v.) injection of rocuronium. Although the incidence of pain on injection
of rocuronium with both fentanyl and sufentanil was high, the intensity was definitely reduced, with most patients falling
in the mild pain group. 相似文献

Background
Spasm through the internal anal sphincter is one of the supposed causes for pain after hemorrhoidectomy, a common and distressing experience. We hypothesized that the addition of topical nifedipine to lidocaine would improve pain control by causing a relaxation of the smooth muscle of the internal anal sphincter.Methods
We conducted a multicentre randomized, double-blind trial to compare the efficacy of 0.3% nifedipine and 1.5% lidocaine ointment versus 1.5% lidocaine ointment alone in reducing pain after hemorrhoidectomy. A physician unaware of the treatment arm measured pain by use of the Analogue Chromatic Continuous Scale (ACCS) at baseline; soon after surgery; at 2, 4, 6, 8 and 24 hours after surgery; on day 7 after surgery; and at a final visit 14 days after surgery. The physician also noted the time to first analgesic administration within 24 hours after surgery.Results
In all, 135 patients per group participated (270 total). Evaluation of the delta ACCS score versus basal value, a covariate for rescue analgesic administration time, revealed better pain control in the group that received nifedipine with lidocaine at 6 hours after surgery and on day 7 (p < 0.011 and p < 0.054, respectively). We noticed no difference between groups for time of administration of rescue analgesic, blood pressure, heart rate or frequency of headache.Conclusion
Although there was no difference between groups for time of administration of rescue analgesic after open hemorrhoidectomy, the patients’ assessment of pain using ACCS showed that the use of topical nifedipine with lidocaine may provide a slight significant difference in favour of the study group at 6 hours and at day 7 after surgery. Narcotic analgesics and nonsteroidal anti-inflammatory drug administration should continue to be recommended. Further research focusing on these outcomes is warranted. 相似文献17.

Background
Pre-emptive intravenous lidocaine infusion is known to improve postoperative pain in abdominal surgery. We assessed the effect of intravenous lidocaine infusion in patients who underwent subtotal gastrectomy.Methods
We conducted a double-blind, placebo-controlled study with patients undergoing subtotal gastrectomy for early gastric cancer divided into 2 groups: 1 group received intravenous lidocaine infusion preoperatively and throughout surgery, and the other received normal saline infusion (placebo). We assessed postoperative outcomes, including pain scores on a visual analogue scale (VAS), administration frequency of patient-controlled analgesia (PCA) and the amount of consumed fentanyl. Postoperative nausea and vomiting, length of hospital stay (LOS), time to return to regular diet and patient satisfaction at discharge were evaluated.Results
There were 36 patients in our study. Demographic characteristics were similar between the groups. The VAS pain scores and administration frequency of PCA were significantly lower in the lidocaine group until 24 hours after surgery, and fentanyl consumption was significantly lower in this group until 12 hours postoperatively compared with the placebo group. The total amount of consumed fentanyl and the total administration frequency of PCA were significantly lower in the lidocaine than the control group. No significant differences were detected in terms of nausea and vomiting, return to regular diet, LOS and patient satisfaction, and there were no reported side-effects of lidocaine.Conclusion
Intravenous lidocaine infusion reduces pain during the postoperative period after subtotal gastrectomy. 相似文献19.

Patients with reflex sympathetic dystrophy, who received transient pain relief from stellate ganglion blocks or lumbar sympathetic blocks and had abnormal isolated cold stress tests, were enrolled in a study to determine the efficacy of intravenous regional bretylium. Each patient received two control treatments (0.5% lidocaine) and two treatments with 0.5% lidocaine and bretylium 1.5 mg/kg in a randomized, double-blind fashion. A standard intravenous regional technique was used with a 300-mm Hg tourniquet pressure for 20 min. Patients kept a daily record of pain relief (0 = no relief, 100% = complete relief). A decrease in pain of more than 30% was considered clinically significant. Therefore, once the patient's pain relief was less than 30%, the next intravenous regional treatment was performed. Bretylium and lidocaine provided more than 30% pain relief for a mean of 20.0 (+/- 17.5) days, whereas lidocaine alone provided relief for only 2.7 (+/- 3.7) days (Mann-Whitney U-test, P less than 0.001). A mean temperature increase in the treated limb of +2.64 +/- 3.41 degrees C above the baseline temperature was noted after bretylium administration, whereas after control treatments the change was -0.086 +/- 1.30 degrees C (Mann-Whitney U-test, P less than 0.02). We conclude that the combination of bretylium and lidocaine is significantly more effective than lidocaine alone when an intravenous block is used to treat reflex sympathetic dystrophy. 相似文献
