Background: Postoperative nausea and vomiting (PONV) is a commonly observed adverse effect of anaesthesia. This study was designed to evaluate the efficacy of granisetron administered orally for preventing PONV in female patients undergoing major gynaecological surgery.
Methods: In a prospective, randomized, placebo-controlled, double-blind study, 120 patients received orally either placebo or granisetron (1 mg, 2 mg or 4 mg) (n=30 for each) 1 h before surgery. The same standard general plus regional anaesthetic technique was employed throughout. Postoperatively, during the first 24 h after anaesthesia, the incidence of PONV and adverse events was recorded by nursing staff.
Results: The incidence of PONV was 47% with placebo, 37% with granisetron 1 mg, 10% with granisetron 2 mg and 10% with granisetron 4 mg (P<0.05; overall Fisher's exact probability test). No difference in the incidence of adverse events was observed among the groups.
Conclusion: Preoperative oral granisetron in a minimum dose of 2 mg is effective for preventing PONV after major gynaecological surgery. 相似文献

BACKGROUND: We evaluated the efficacy of granisetron, 5-hydroxytryptamine type 3 receptor antagonist, given orally, preoperatively, for the prevention of postoperative vomiting in children undergoing general anaesthesia for surgery (inguinal hernia, phimosis-circumcision). METHODS: In a randomized, double-blinded manner, 100 children, ASA physical status I, aged 4-11 years, received orally placebo or granisetron at three different doses (20 microg x kg(-1), 40 microg x kg(-1), 80 microg x kg(-1)) 60 min before surgery (n=25 of each). The same standard general anaesthetic technique was used. RESULTS: The percentage of patients being emesis-free during 0-6 h after anaesthesia was 56% with placebo, 64% with graniseron 20 microg x kg(-1) (P=0.773), 88% with granisetron 40 microg x kg(-1) (P=0.027) and 92% with granisetron 80 microg x kg(-1) (P=0.01); the corresponding rate during 6-24 h after anaesthesia was 60%, 68% (P=0.768), 92% (P=0.02) and 92% (P=0.02) (P-values versus placebo). No clinically serious adverse events were observed in any of the groups. CONCLUSIONS: In summary, preoperative oral granisetron 40 microg x kg(-1) is effective for the prevention of vomiting following paediatric surgery (inguinal hernia, phimosis-circumcision). Increasing the doses to 80 microg x kg(-1) provides no demonstrable additional benefit. 相似文献

Comparison of ramosetron and granisetron for preventing postoperative nausea and vomiting after gynecologic surgery. 总被引:3,自引:0,他引:3
In a prospective, randomized, double-blinded study, we evaluated the efficacy of granisetron and ramosetron for preventing postoperative nausea and vomiting (PONV) in major gynecologic surgery. One hundred twenty patients, ASA physical status I or II, aged 23-65 yr, received i.v. granisetron 2.5 mg or ramosetron 0.3 mg (n = 60 each) at the end of surgery. A standard general anesthetic technique and postoperative analgesia were used. The incidence of a complete response, defined as no PONV and no need for another rescue medication, 0-3 h after anesthesia was 87% with granisetron and 90% with ramosetron; the corresponding incidence 3-24 h after anesthesia was 85% and 90%; the corresponding incidence 24-48 h after anesthesia was 70% and 92% (P < 0.05). No clinically serious adverse events due to the drugs were observed in any of the groups. In conclusion, prophylactic therapy with ramosetron is more effective than granisetron for the longterm prevention of PONV after major gynecologic surgery. Implications: We compared the efficacy of granisetron and ramosetron for preventing postoperative nausea and vomiting in major gynecologic surgery. Prophylactic therapy with ramosetron was more effective than granisetron for preventing postoperative nausea and vomiting 24-48 h after anesthesia. 相似文献

BACKGROUND: Laparoscopic cholecystectomies are associated with an appreciably high rate of postoperative nausea and vomiting (PONV). This study was designed to compare the effectiveness of granisetron plus dexamethasone with granisetron alone for the prevention of postoperative nausea and vomiting in patients after laparoscopic cholecystectomy. METHODS: In a randomized, double-blind study, 120 patients of both sexes received granisetron 40 micro g kg-1 alone or granisetron 40 micro g kg-1 plus dexamethasone 8 mg (n=60 of each) intravenously immediately before induction of anesthesia. Perioperative anesthetic care was standardized in all patients. Patients were then observed for 24 h after administration of the study drug. RESULTS: A complete response (defined as no PONV and no need for another rescue antiemetic) was achieved in 83% of the patients given granisetron and in 95% of the patients given granisetron plus dexamethasone (P<0.05). The overall cumulative incidences (0-24 h) of PONV were 11 (18.3%) in the granisetron and three (5%) in the combination group. No difference in adverse events were observed in any of the groups. CONCLUSION: The combination (granisetron plus dexamethasone) further increases the chance of complete response than granisetron alone. Therefore, the combination might be considered clinically relevant in a high risk setting. 相似文献

In this randomized, double-blind, parallel group, placebo-controlled,
dose-ranging study, we have compared three doses (0.1 mg, 1.0 mg and 3.0
mg) of the 5-HT3 receptor antagonist, granisetron (Kytril), as prophylactic
therapy for the prevention of postoperative nausea and vomiting. The aims
were to determine the optimal dose of granisetron and to evaluate its
safety profile. We studied 527 adult patients, undergoing elective open
abdominal surgery or vaginal hysterectomy during general anaesthesia.
Antiemetic prophylaxis with a single dose of granisetron 1.0 mg or 3.0 mg
resulted in a significant reduction (P < 0.001 compared with placebo) in
the numbers of patients experiencing postoperative vomiting, or nausea, or
who achieved total control during the postoperative periods 0-6 h and 0-24
h. The two higher doses of granisetron (1.0 mg and 3.0 mg) provided
effective prophylaxis against vomiting, with 78% and 77% of patients,
respectively, being free from vomiting in the first 6 h after surgery, and
63% and 62% in the first 24 h. This compares with 50% and 34% at 0-6 h and
0-24 h, respectively, in the placebo group. Granisetron was well tolerated
and the optimum dose was 1.0 mg.

In a randomized, placebo-controlled, double-blind trial, we compared the efficacy of dolasetron, dexamethasone, and metoclopramide in a preventing postoperative nausea and vomiting in women undergoing breast surgery. Patients were allocated randomly to one of four groups (20 patients each): group A received 12.5 mg dolasetron, group B received 8 mg dexamethasone, group C received 20 mg metoclopramide, and group D received placebo intravenously. If patients complained of retching or vomiting or if patients demanded an antiemetic, 1.25 mg droperidol was administered intravenously. To quantify postoperative nausea and vomiting, the following score was used: 0 = no nausea, 1 = nausea, 2 = retching, 3 = single vomiting, 4 = multiple vomiting. Dolasetron and dexamethasone reduced the postoperative nausea and vomiting score significantly (p < 0.02 versus metoclopramide; p < 0.0001 versus placebo). Metoclopramide also reduced the postoperative nausea and vomiting score (p < 0.02 versus placebo). Fisher's exact test showed a significant reduction of vomiting in the dolasetron and dexamethasone groups compared with metoclopramide-treated patients (p < 0.007) and placebo-treated patients (p < 0.000006) and a significantly lower rate of nausea in comparison to the placebo group (p < 0.009). There were no significant differences between the metoclopramide and the placebo groups (using Fisher's exact test). The use of postoperative droperidol was significantly lower in both the dolasetron group (p < 0.04 versus metoclopramide; p < 0.0001 versus placebo) and dexamethasone group (p < 0.04 versus metoclopramide; p < 0.0001 versus placebo), as well as in the metoclopramide group (p < 0.02 versus placebo). Intravenous dolasetron and dexamethasone were equally effective and both are more effective than metoclopramide for preventing vomiting after breast surgery. Also both were significantly superior to either metoclopramide or placebo for postoperative nausea and vomiting and the need for droperidol rescue. 相似文献

In a randomised, double-blind study, a transdermal patch containing either hyoscine or placebo was applied post-auricularly in 190 adult patients under 65 year old, seven to twelve hours prior to their undergoing minor orthopaedic or plastic surgery under thiopentone/nitrous oxide/halothane general anaesthesia. In the first 24 hours after surgery 34% of patients vomited. The incidence of nausea (31% vs 54%; P less than 0.01) and the number of episodes of vomiting (66 vs 125; P less than 0.05) during the first 24 hours were significantly less with hyoscine than with placebo. The hyoscine group required fewer doses of antiemetic than the placebo group (12 vs 27; P less than 0.05). Side-effects were mild, the only difference between the two groups being the frequency of dry mouth immediately preoperatively. No differences were seen in the second 24 hours after surgery. We conclude that transdermal hyoscine is moderately effective in reducing the occurrence of postoperative nausea and vomiting following minor surgery. 相似文献

PURPOSE: To compare the efficacy of ramosetron with granisetron for the prevention of postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy. METHODS: In a randomized, double-blind study, 80 female inpatients received 3 mg granisetron or 0.3 mg ramosetron i.v. (n=40 of each) at the completion of surgery The standardized anesthetic included isoflurane and nitrous oxide in oxygen. RESULTS: Complete response, defined as no PONV, during the first 24 hr (0-24 hr) after anesthesia was 85% with granisetron and 93% with ramosetron, respectively (P=0.241); the corresponding incidence during the next 24 hr (24-48 hr) after anesthesia was 63% and 90% (P=0.004). No clinically important adverse events due to the study drug were observed in any of the groups. CONCLUSION: Ramosetron was more effective than granisetron for prevention of PONV during 0-48 hr after anesthesia for laparoscopic cholecystectomy. 相似文献

Study ObjectiveTo investigate whether betamethasone decreases the incidence of postoperative nausea/vomiting (PONV) and reduces postoperative pain following partial mastectomy.DesignProspective randomized, double-blinded study.SettingOperating room and Postanesthesia Care Unit of a university hospital.Patients80 ASA physical status 1 and 2 women scheduled for elective breast cancer surgery.InterventionsPatients were randomly allocated to two groups in double-blinded fashion: Group B (betamethasone; 37 pts) and Group C (control; 38 pts). Group B received 8 mg of betamethasone intravenously before the start of surgery.MeasurementsThe rate of PONV and pain were recorded using a numeric rating scale (NRS; 0–10), as well as rescue doses of antiemetics (ondansetron) and analgesics (ketobemidone).Main ResultsThere was a significant lower incidence of postoperative nausea (PON) scoring NRS ≥ 1 in Group B in the 4 to 12-hour period compared with Group C (P = 0.02). The cumulative incidence of PON was 57% in Group B versus 68% in Group C (P = 0.27). The overall incidence of postoperative vomiting (POV) was 18% and 20% in Groups B and C, respectively. Postoperative pain was reduced by 40% in Group B in the 4 to 12-hour period, but the mean dose of postoperative rescue analgesic did not differ between the groups.ConclusionsPreoperative betamethasone reduces the severity of PONV and pain in patients undergoing elective breast surgery. 相似文献

Background: Prophylactic use of granisetron, a selective Shydroxytryptamine type 3 receptor antagonist, reduces the incidence of nausea and vomiting after breast surgery. This study was undertaken to determine the minimum effective dose of granisetron in the reduction of postoperative nausea and vomiting (PONV) in patients undergoing general anaesthesia for breast surgery.
Methods: In a randomized, double-blind manner, 120 female patients aged 42–66 years were assigned to receive either placebo (saline) or granisetron in a dose of 20 μg · kg-1 , 40 μg · kg-1 and 80 μg · kg-1 i.v. immediately before the induction of anaesthesia. A standard general anaesthetic technique was employed throughout. The POW and safety assessments were performed continuously during the first 24 h after anaesthesia.
Results: There were no significant differences among the groups with regard to patient demographics, surgical procedures, anaesthetics administered and analgesics given. The incidence of PONV was 47%, 43%, 17% and 17% after administration of placebo and granisetron 20 μg -kg-1 , 40 μg kg-1 and 80 μg kg-1 , respectively. Granisetron 40 μg kg-1 was as effective as 80 μ g - kg-1 and both resulted in significant reductions of the incidence of PONV compared with placebo and granisetron 20 μg kg-1 ( P < 0.05). No differences in the incidence of adverse events were observed among the groups.
Conclusion: Granisetron 40 μg · kg-1 appears to be the minimum effective dose for reducing POW in patients undergoing general anaesthesia for breast surgery. 相似文献

Background. Administration of supplemental oxygen 80% has beenshown to halve the incidence of postoperative nausea and vomiting(PONV). We tested the efficacy of supplemental oxygen 50% indecreasing the incidence of PONV after breast surgery. Methods. One hundred patients receiving standardized sevofluraneanaesthesia were randomly assigned to two groups: oxygen 30%administration (Group 30); and oxygen 50% administration (Group50). Oxygen was administered during surgery and for 2 hfrom the end of surgery. Results. The incidence of PONV over 24 h after surgeryshowed no difference between the groups: 82% in Group 30 and89% in Group 50. However, during the postoperative oxygen administration,eight patients vomited in Group 30, compared with none in Group50 (P<0.05). After oxygen therapy ceased, there was no differencein the incidence of vomiting between the groups. Nausea andneed for rescue antiemetics did not differ between the groups. Conclusion. The incidence of vomiting decreased during the shortpostoperative administration of supplemental oxygen 50%. However,perioperative oxygen 50% administration did not prevent PONVover the 24-h follow-up period in patients undergoing breastsurgery performed under general anaesthesia.

In a prospective, randomized, double-blinded trial, we evaluated the efficacy of two antiemetics given orally, granisetron and perphenazine, for preventing postoperative vomiting after tonsillectomy with or without adenoidectomy in children. One hundred pediatric patients, ASA physical status I, aged 4-10 yr, received either granisetron 40 microg/kg or perphenazine 70 microg/kg (n = 50 each) orally 1 h before surgery. We used a standard general anesthetic technique. The rate of complete response, defined as no emesis and no need for rescue antiemetic medication, during 0-3 h after anesthesia was 86% with granisetron and 60% with perphenazine; the corresponding rate 3-24 h after anesthesia was 86% and 62%, respectively (P < 0.05). No serious adverse events were observed in any of the groups. In conclusion, preoperative oral granisetron is more effective than perphenazine for preventing postoperative vomiting in children undergoing tonsillectomy with or without adenoidectomy. IMPLICATIONS: We compared the efficacy of granisetron and perphenazine given orally for preventing postoperative vomiting after tonsillectomy with or without adenoidectomy in children. Preoperative oral granisetron was more effective than perphenazine. 相似文献

Combination of granisetron and droperidol in the prevention of nausea and vomiting after middle ear surgery. 总被引:1,自引:0,他引:1
STUDY OBJECTIVES: To evaluate the efficacy and safety of granisetron-droperidol combination for the prevention of postoperative nausea and vomiting (PONV) after middle ear surgery. DESIGN: Prospective, randomized, double-blind study. SETTING: University hospital. PATIENTS: 150 ASA physical status I patients (108 females, 42 males) scheduled for elective middle ear surgery. INTERVENTIONS: Patients received granisetron 40 micrograms/kg (n = 50), droperidol 20 micrograms/kg (n = 50), or granisetron 40 micrograms/kg plus droperidol 20 micrograms/kg (n = 50) intravenously immediately before induction of anesthesia. MEASUREMENTS AND MAIN RESULTS: A standard general anesthetic technique and postoperative analgesia were used throughout the study. A complete response, defined as no PONV and no need for another rescue antiemetic, from 0 to 3 hours after anesthesia occurred in 78%, 56%, and 94% of patients who had received granisetron, droperidol, and granisetron plus droperidol, respectively. The corresponding incidence between 3 and 24 hours after anesthesia was 80%, 52% and 94%. Thus, a complete response within the first 24-hour postanesthetic period was greater in patients receiving granisetron-droperidol combination than in those receiving granisetron alone or droperidol alone (p < 0.05). No clinically adverse events were observed in any of the groups. CONCLUSIONS: A combination of granisetron and droperidol is more effective than droperidol or granisetron alone for the prevention of PONV after middle ear surgery. 相似文献

We have compared the efficacy and safety of the combination granisetron-
droperidol with each antiemetic alone in preventing postoperative nausea
and vomiting (PONV) after breast surgery. In a randomized, double-blind
study, 150 female patients received granisetron 3 mg, droperidol 1.25 mg or
granisetron 3 mg with droperidol 1.25 mg (n = 50 each) i.v., immediately
before induction of anaesthesia. A standard general anaesthetic technique
was used. The incidence of PONV during the first 24 h after anaesthesia was
18% with granisetron, 38% with droperidol and 4% with the
granisetron-droperidol combination (P < 0.05; overall Fisher's exact
probability test). We conclude that the granisetron-droperidol combination
was more effective than each antiemetic alone in the prevention of PONV in
female patients undergoing breast surgery.

Prophylaxis with oral granisetron for the prevention of nausea and vomiting after laparoscopic cholecystectomy: a prospective randomized study 总被引:2,自引:0,他引:2
HYPOTHESIS: Laparoscopic cholecystectomy is associated with a relatively high incidence of postoperative nausea and vomiting when no prophylactic antiemetic is given. This study assesses the efficacy and safety of oral granisetron hydrochloride for the prevention of nausea and vomiting after laparoscopic cholecystectomy. DESIGN: A prospective, randomized, double-blind, placebo-controlled study. SETTING: University teaching hospital. PATIENTS: The study comprised 120 patients, 92 women and 28 men, undergoing laparoscopic cholecystectomy. INTERVENTIONS: Patients received orally either placebo or granisetron at 3 different doses (1 mg, 2 mg, and 4 mg; n = 30 of each) 60 minutes before surgery. A standard general anesthetic technique and postoperative analgesia were used. MAIN OUTCOME MEASURES: Emetic episodes were recorded during the first 24 hours after anesthesia. RESULTS: The incidence of patients who were emesis-free 24 hours after anesthesia was 60% with 1 mg of granisetron (P =.40), 83% with 2 mg of granisetron (P =.01), and 83% with 4 mg of granisetron (P =.01), compared with placebo (53%). No clinically important adverse effects were observed in any of the groups. CONCLUSION: Preoperative oral granisetron in doses higher than 2 mg is effective for the prevention of nausea and vomiting after laparoscopic cholecystectomy. 相似文献
