The efficacy of a single dose antibiotic regimen in adults undergoing tonsillectomy.
A prospective, randomized, double-blinded, placebo-controlled clinical trial was conducted in 41 patients evaluating the effect of a single preoperative dose of intravenous dexamethasone on postoperative vomiting and pain in children undergoing elective tonsillectomy. Dexamethasone was found to significantly reduce the incidence of vomiting in the first 24 hours postoperatively (P = 0.02), the time to first intake of solids (P = 0.001), the need to administer a rescue antiemetic (P = 0.005) and intravenous fluid therapy requirements (P = 0.006) in the postoperative period. No significant difference was found between the dexamethasone and placebo groups in the time to first intake of fluids, pain scores or analgesic requirement postoperatively. These results indicate that dexamethasone substantially reduces morbidity after tonsillectomy in children. To determine whether the intravenous administration of dexamethasone sodium phosphate before tonsillectomy and adenoidectomy can reduce the morbidity from, and increase the safety of, this procedure.
                Prospective, randomized, double-blind, placebo-controlled clinical trial.
                A university medical center, caring for both ambulatory and hospitalized children.
                Eighty children aged 3 to 15 years undergoing tonsillectomy and adenoidectomy for either chronic tonsillitis or adenotonsillar hypertrophy (obstructive sleep apnea and/or upper airway obstruction).
                Forty-one children received intravenous dexamethasone sodium phosphate (1 mg/kg up to 16 mg) and 39 received placebo before undergoing an electrocautery dissection tonsillectomy and adenoidectomy.
                Postoperative oral intake, pain, vomiting, temperature, and complications.
                Patients who received intravenous dexamethasone had significantly less trismus, vomiting, and elevations of temperature 6 hours after surgery and more oral intake (liquids and soft solids) at 24 hours. Three children, all of whom were in the placebo group, had emergency department visits for pain and dehydration. Each group had one child who had a secondary hemorrhage (no surgery needed), one child who had pneumonia, and one child who had night terrors.
                Treatment with intravenous dexamethasone before electrocautery tonsillectomy and adenoidectomy is safe, increases early postoperative oral intake, and decreases morbidity. The purpose of this study is to determine whether a single dose of dexamethasone 0.5mg/kg administered before surgery could decrease post operative vomiting and pain and improves oral intake in the first 24-hours after pediatric tonsillectomy procedures.
                It is a randomized, double blind, placebo controlled study. Sixty children age 2-12-years ASA 1 and 11 were scheduled for tonsillectomy, dexamethasone (n=29) and control group (n=31) were enrolled in the study. Dexamethasone group received 0.5mg/kg intravenous dexamethasone and control group received saline at the time of induction. The anesthetic regimen and surgical procedures were standardized for all patients. All patients were observed in post anesthesia care unit (PACU) and ward for post operative vomiting, pain, need for rescue antiemetic or analgesia and time for first oral intake for 24-hours.
                Data from 60 patients were analyzed. The overall incidence of early as well as late vomiting was significantly less in dexamethasone as compared to control group (37% versus 74% P=0.016), overall incidence of retching was 29% in control and 3.4% in dexamethasone (p=0.008). Vomiting once or more than once was significantly high in control as compared to dexamethasone group. The need for rescue antiemetic, the time to first oral intake and analgesic requirements did not show any significant difference in both groups.
                Dexamethasone is considered safe and there was no adverse effects associated with a single dose of dexamethasone. Although the need for rescue antiemetic, time to oral intake and analgesia requirements in both groups were not significant, however, we found that dexamethasone does have antiemetic properties as overall incidence of retching and vomiting was significantly less in dexamethasone group as compared to control group in children who underwent tonsillectomy. The study goal was to determine whether the combination of dexamethasone with preemptive analgesia has an additive effect in further improving recovery.
                We conducted a prospective, randomized, double-blinded trial of 50 children undergoing tonsillectomy at a university ambulatory surgery center. One study group received 1 intravenous dose of dexamethasone, and another group received 1 dose of saline solution. All patients received tonsillar fossa injections of ropivacaine plus clonidine before tonsil excision.
                The 2 study groups were similar in main outcome measurements. Pain intensity and quality of life were not statistically different between the groups. There was a small trend to less trismus and less cumulative codeine use in the steroid group. Overall, there was a very low incidence of nausea and vomiting in both groups, which may have been due to the preemptive analgesia.
                Dexamethasone does not significantly improve the morbidity of pediatric tonsillectomy when preemptive analgesia with ropivacaine and clonidine is used concurrently. Previous studies on dexamethasone's antiemetic and analgesic potential in children undergoing tonsillectomy have produced conflicting results. The aim of this study was to evaluate the effects of a single dose of dexamethasone on the incidence and severity of postoperative vomiting and pain in children undergoing electrocautery tonsillectomy under standardized general anesthesia.
                In a double-blinded study, 120 patients were randomly allocated to receive either dexamethasone 0.5 mg.kg(-1) (maximum dose 8 mg) iv or an equivalent volume of saline preoperatively. The incidence of early and late vomiting, need for rescue antiemetics, time to first oral intake, time to first demand of analgesia and analgesic consumption were compared in both groups. Pain scores used included Children's Hospital Eastern Ontario Pain Scale, "faces", and a 0-10 visual analogue pain scale.
                Compared with placebo, dexamethasone significantly decreased the incidence of early and late vomiting (P < 0.05, P < 0.001 respectively). Fewer patients in the dexamethasone group needed antiemetic rescue (P < 0.01). The time to first oral intake was shorter, and the time to first dose of analgesic was longer in the dexamethasone group (P < 0.01). Pain scores 30 min after extubation were lower (P < 0.05) in the dexamethasone group. At 12 and 24 hr postoperative swallowing was still significantly less painful in the dexamethasone group than in the control group (P < 0.01).
                Preoperative dexamethasone 0.5 mg.kg(-1) iv reduced both postoperative vomiting and pain in children after electrocautery tonsillectomy. To determine the effects of a single dose of dexamethasone sodium phosphate on postoperative morbidity in children undergoing tonsillectomy.
                Randomized, double-blind, placebo-control clinical trial.
                Academic, tertiary care children's hospital.
                Sixty-nine children (35 boys, 34 girls), aged 3 to 18 years, undergoing tonsillectomy with or without adenoidectomy.
                Patients were randomized to receive a single dose of intravenous dexamethasone or saline.
                Pain scores, determined by a Faces Scale, were obtained at 4-hour intervals during the first postoperative day and daily for 7 days thereafter. Total use of an analgesic; type of diet; level of activity; presence of halitosis, nausea, emesis, or fever; and incidence of postoperative bleeding were also compared between the two groups.
                The two groups of children were similar in age, gender, diagnosis, and surgical time. Pain scores in the postoperative period were identical while the patients were in the hospital and for the first 7 days after discharge. No statistically significant differences were noted in pain scores, nausea, emesis, halitosis, analgesic medications required, diet, or activity levels between the two groups of patients.
                A single intraoperative dose of dexamethasone did not appreciably affect postoperative morbidity in children undergoing tonsillectomy. In this prospective, randomized, double-blind, placebo-controlled study, we examined the effect of preoperative dexamethasone on postoperative nausea and vomiting (PONV) and 24-h recovery in children undergoing tonsillectomy. One hundred thirty children, 2-12 yr of age, ASA physical status I or II, completed the study. All children received oral midazolam 0.5-0.6 mg/kg preoperatively. Anesthesia was induced with halothane and nitrous oxide in 60% oxygen and maintained with nitrous oxide and isoflurane. Intubation was facilitated by mivacurium 0.2 mg/kg. Each child received fentanyl 1 microgram/kg i.v. before initiation of surgery, as well as dexamethasone 1 mg/kg (maximal dose 25 mg) (steroid group) or an equal volume of saline (control group). Intraoperative fluids were standardized to 25-30 mL/kg lactated Ringer's solution. All tonsillectomies were performed under the supervision of one attending surgeon using an electrodissection technique. Postoperatively, fentanyl and acetaminophen with codeine elixir were administered as needed for pain. Rescue antiemetics were administered when a child experienced two episodes of retching and/or vomiting. Before home discharge, the incidence of PONV, need for rescue antiemetics, quality or oral intake, and analgesic requirements did not differ between groups. However, during the 24 h after discharge, more patients in the control group experienced PONV (62% vs 24% in the steroid group) and complained of poor oral intake. Additionally, more children in the control group (8% vs 0% in the steroid group) returned to the hospital for the management of PONV and/or poor oral intake. The preoperative administration of dexamethasone significantly decreased the incidence of PONV over the 24 h after home discharge in these children. Implications: In this double blind, placebo-controlled study, we examined the efficacy of a single large dose (1 mg/kg; maximal dose 25 mg) of preoperative dexamethasone on posttonsillectomy postoperative nausea and vomiting (PONV) in children 2-12 yr of age undergoing tonsillectomy. Compared with placebo, dexamethasone significantly decreased the incidence of PONV in the 24 h after discharge, improved oral intake, decreased the frequency of parental phone calls, and resulted in no hospital returns for the management of PONV and/or poor oral intake. We evaluated the effect of dexamethasone on vomiting after elective tonsillectomy in 133 healthy children aged 2-12 yr in a randomized, stratified, blocked, double-blind, placebo-controlled study. General anesthesia was induced by inhalation of N2O and halothane or intravenously (IV) with propofol. Anesthesia was maintained with N2O and halothane. Dexamethasone 150 micrograms/kg up to a maximum dose of 8 mg, or placebo, was administered IV before surgery. All patients received 1.5 mg/kg codeine intramuscularly (IM) intraoperatively. Perioperative IV fluids, management of emesis, postoperative pain and hospital discharge criteria were all standardized. The groups were similar with respect to number, age, weight, length of surgery, and estimated intraoperative blood loss. Dexamethasone reduced the overall incidence of vomiting from 72% (placebo) to 40% (P < 0.001). Vomiting, both in-hospital and postdischarge, was decreased by the prophylactic administration of dexamethasone. Each episode of in-hospital vomiting prolonged discharge by 13 +/- 2 min, mean +/- SD (P < 0.001). In conclusion, dexamethasone markedly decreased vomiting by healthy children after elective tonsillectomy in an ambulatory hospital setting. A prospective, randomized, double-blind study to determine the postoperative efficacy of steroids in tonsillectomy was performed in 49 children. A single dose of intravenous dexamethasone or placebo was administered after each child was anesthetized. Postoperatively each child was examined for objective signs of trismus (measured by interincisor distance), temperature elevation, and weight loss, as well as for subjective signs of mouth odor, oral intake, pain, level of activity, and analgesic usage. There were no statistical differences noted in any of the variables compared in the two groups and the complication rates were also similar. In this double-blinded, randomized, placebo-controlled study, we assessed the effect of dexamethasone 0.5 mg/kg IV administered preoperatively in 110 children 2-12 yr old, undergoing electrodissection adenotonsillectomy, using a standardized anesthetic technique. The incidence of early and late vomiting, the time to first oral intake, the quality of oral intake, the satisfaction scores, and the duration of IV hydration were compared in both groups. The overall incidence of vomiting, as well as the incidence of late vomiting, was significantly less in the Dexamethasone group as compared with the Saline group (23% and 19% vs 51% and 34%, respectively). The time to first oral intake and the duration of IV hydration were shorter in the Dexamethasone group compared with the Saline group (P < 0.05). The quality of oral intake and the satisfaction scores were better in the Dexamethasone group than in the Saline group (P < 0.05). This report confirms the beneficial effect of IV dexamethasone on both vomiting and oral intake in children undergoing electrodissection adenotonsillectomy.
                In this double-blinded, placebo-controlled study, we examined the efficacy of a single dose of dexamethasone 0.5 mg/kg IV on posttonsillectomy vomiting and oral intake in children 2-12 yr old. Dexamethasone significantly decreased the incidence of postoperative vomiting during the first 24 h, shortened the time to the first oral intake and the duration of IV hydration, and improved the quality of oral intake and the satisfaction scores of the patients. Postoperative morbidity in patients undergoing tonsillectomy with or without adenoidectomy includes inadequate oral intake, pain, nausea, vomiting and bleeding. The purpose of this study is to evaluate the effect of preoperative 0.5 mg/kg i.v. dexamethasone on postoperative early oral intake, pain, vomiting in patients undergoing adenotonsillectomy while performing standard anesthesia technique and sharp dissection tonsillectomy.
                In this prospective, double-blinded, placebo-controlled study 62 children, aged 4-12 years, who underwent tonsillectomy with or without adenoidectomy were randomly assigned to receive single dose of 0.5 mg/kg i.v. dexamethasone preoperatively. Patients started to receive 100 ml of clear fluids 2 h postoperatively, then were offered every hour. When pain score was 3 or above, paracetamol was given for pain control. Tolerating 400 ml of clear fluids, no bleeding and no vomiting were accepted as discharge criteria. The discharge time was also recorded. The incidence of early vomiting, pain scores, amount of oral intake were recorded until the discharge time.
                Compared with placebo, the patients who received preoperative dexamethasone had significantly less pain score during the first 6 h postoperatively (p<0.05), adequate amount of oral intake time was shorter (p<0.05) and the discharge time was earlier (p<0.05). No difference was found in vomiting incidence in both groups.
                Preoperative dexamethasone use significantly reduces early posttonsillectomy pain, improves oral intake and facilitates meeting the discharge criteria while using standard anesthesia technique and sharp dissection tonsillectomy without any significant side effects. The effects of dexamethasone and perphenazine on vomiting after tonsillectomy in children were compared in 226 healthy children aged 2-12 yr. The study was randomized, stratified, blocked, and double-blind. Anesthesia was induced intravenously (I.V.) with propofol or by inhalation with halothane and N2O. Dexamethasone 150 microg/kg or perphenazine 70 microg/kg was administered I.V. after the induction of anesthesia in a double-blind fashion. Perioperative management of emesis, pain, fluids, and patient discharge was all standardized. The groups had similar demographic characteristics. Perphenazine significantly reduced the incidence of in-hospital vomiting compared with dexamethasone (13% vs 36%, P < 0.001). The incidence of out-of-hospital vomiting was almost identical. Overall, the incidence was significantly different for perphenazine vs dexamethasone (33% vs 46%, P = 0.04) using logistic regression analysis. Of note, sex and induction technique were significant predictors of postoperative vomiting (P < 0.05) using logistic regression analysis, with male patients and those patients undergoing I.V. induction vomiting less. In conclusion, perphenazine more effectively decreases vomiting by children after tonsillectomy in an ambulatory hospital setting compared with dexamethasone.
                Postoperative vomiting can have many debilitating effects, and children undergoing tonsillectomy are at particular risk. We compared the effects of dexamethasone and perphenazine on vomiting after tonsillectomy in 266 children. We found perphenazine more effective than dexamethasone before discharge from hospital but that the two drugs have similar effects after discharge. A prospective, randomized, double-blind study to determine the postoperative effects of steroids in tonsillectomy was performed on 25 children from 4 to 12 years of age. A single intravenous dose of dexamethasone or a placebo was administered at onset of surgery. Other preoperative and postoperative medications, including antibiotics, anesthesia, and surgical techniques were standardized as noted in this article. The ability to return to a full or semifull diet occurred on the third and fourth postoperative days, significantly sooner in the steroid-treated patients than in the control patients. By the fifth and sixth days, the control group were eating as well as those children who received steroids. No significant differences were observed in postoperative pain, nausea, emesis, fever, or in the need for postoperative pain medications. This preliminary article concludes that a single preoperative dose of steroid results in an earlier return to a normal (full) diet in children who had undergone tonsillectomy. The 5-HT3 antagonists are effective in reducing postoperative nausea and vomiting (PONV) associated with paediatric tonsillectomy. Although prophylactic tropisetron can reduce the incidence of PONV by half, the resulting level of over 40% is still unacceptably high. The aim of this study was to evaluate the effect of adding dexamethasone to tropisetron. In a blinded study, 59 children (mean age 6.1 years) were administered 0.1 mg.kg-1 up to 2 mg of tropisetron and 66 children (mean age 5.7 years) received the same dose of tropisetron plus 0.5 mg.kg-1 up to 8 mg of dexamethasone. Both drugs were given intravenously during induction of anaesthesia for tonsillectomy. During the inpatient stay of 24 h, the incidence of postoperative vomiting in the tropisetron alone group was 53% compared with 26% in the combination group (P=0.002, chi-squared). A significant reduction in nausea from 53% to 30% was also observed (P=0.02). Parents completed a daily diary for 5 days following discharge. Delayed vomiting occurred in 27% and 11% of the tropisetron and combination therapy groups, respectively (P=0.025) Sixteen percent and 9%, respectively, required medical attention (P=0.27). Tropisetron plus dexamethasone is more effective than tropisetron alone in reducing the incidence of PONV following paediatric tonsillectomy. Several studies have indicated that antibiotics given for 5-7 days post-tonsillectomy are beneficial. A prospective double blind randomized study was undertaken to evaluate the efficacy of a long-acting antibiotic (Cefonicid) given prophylactically at the time of tonsillectomy. Dependent variables were percent weight loss, number of doses of pain medications required postoperatively, the number of days required to resume a normal diet, and return to work. The results of all independent tests indicated that there were no statistically significant differences between the Cefonicid group and the placebo group. The results of this study indicate that single dose prophylactic application of Cefonicid is not effective in adults undergoing tonsillectomy.
The evidence suggests that a single intravenous dose of dexamethasone is an effective, safe and inexpensive treatment for reducing morbidity from pediatric tonsillectomy.
