A double-blind comparison of nomifensine and amitriptyline in the treatment of depression

Ong SB, Lee CT

Acta Psychiatr Scand, 1981 Mar;63(3):198-207.
PMID: 7015790

A double-blind study was carried out to compare the efficacy and tolerability of nomifensine and amitriptyline in 17 Malaysian patients with moderate to severe depression. The two drugs did not differ with regard to antidepressant effect but nomifensine-treated subjects report fewer side-effects with no complaints of palpitations. Nomifensine also increases capacity for work and activity.

Fulltext Twice daily cimetidine in the initial treatment of chronic gastric ulcer--a double-blind placebo-controlled trial

Tay HH, Yap I, Guan R, Koh PS, LaBrooy SJ, Kang JY

Med J Malaysia, 1988 Jun;43(2):181-5.
PMID: 3070309

Thirty-one patients with endoscopically proven chronic gastric ulcer completed a randomised double-blind trial comparing the effects of cimetidine and placebo on ulcer healing. Seventeen patients received cimetidine 400 mg bid and 14 patients received placebo. Repeat endoscopy at six weeks showed that the ulcer had healed in 12 patients (71%) receiving cimetidine and in four patients (29%) receiving placebo (p=O.032). Non-smokers healed their ulcers better than smokers (83% vs 35%, p=O.023). The use of cimetidine was not associated with any adverse effects.

Fulltext Shortening the onset time of atracurium for rapid tracheal intubation

Jaradi H, Tay KH, Delilkan AE

Med J Malaysia, 1989 Jun;44(2):143-6.
PMID: 2626122

The 'Priming principle' applied to non-depolarizing muscle relaxant atracurium was studied in 60 patients. This was a double blind study. The conditions observed for intubation were graded and the efficacy of priming dose of atracurium for shortening the onset time of intubation was studied. The patients were of ASA classification I and II and received standard premedication. The purpose of the study was to use the priming dose of atracurium to shorten the onset time of intubating dose of atracurium. This would be desirable in conditions requiring rapid intubation and in situations when the depolarizing muscle relaxant suxamethonium is contra-indicated. The results were statistically significant.

Omeprazole compared with ranitidine once daily in the treatment of duodenal ulcer

Chelvam P, Goh KL, Leong YP, Leela MP, Yin TP, Ahmad H, et al.

J Gastroenterol Hepatol, 1989;4 Suppl 2:53-61.
PMID: 2491362

A double-blind randomized study in 230 Malaysian patients with duodenal ulcer was conducted to compare the proton-pump inhibitor, omeprazole 20 mg, given once daily in the morning, with ranitidine 300 mg, administered once daily at night. After 2 and 4 weeks of treatment, 222 and 220 patients, respectively, were evaluable according to the study protocol. Omeprazole produced significantly higher healing rates than ranitidine at both 2 weeks (75% versus 46%, respectively, P less than 0.0001) and 4 weeks (97% versus 83%, respectively, P = 0.001). Ulcer symptoms were relieved more rapidly by omeprazole than ranitidine. After 2 weeks, daytime epigastric pain was reported by 30% of ranitidine-treated patients but only by 15% of omeprazole-treated patients, which is a statistically significant difference (P = 0.004). No major clinical or biochemical side effects were recorded for either omeprazole or ranitidine. In conclusion, omeprazole 20 mg was found to be superior to ranitidine 300 mg administered once daily for the treatment of duodenal ulcer as measured by ulcer healing and pain relief.

A double-blind placebo-controlled trial of zopiclone 7.5 mg and temazepam 20 mg in insomnia

Ngen CC, Hassan R

Int Clin Psychopharmacol, 1990 Jul;5(3):165-71.
PMID: 2230060

Zopiclone, a cyclopyrrolone with hypnotic properties was compared with temazepam and placebo in the treatment of insomnia. After a week's washout period, suitable subjects were allocated at random to zopiclone 7.5 mg or temazepam 20 mg or placebo for 2 weeks. Measurements of psychomotor function using the Leed's psychomotor tester and letter cancellation were carried out on day 0, 7 and 14. Sleep latency, duration of sleep and number of times waking during the night were recorded on a sleep diary filled by the subjects nightly. Forty-four subjects completed the trial, 15 taking zopiclone, 16 taking temazepam and 10 taking placebo. Both zopiclone and temazepam had significant hypnotic properties when compared to placebo. Zopiclone increased total sleep time in both weeks of the trial while temazepam increased sleep time in the first week only. There was no significant deterioration in psychomotor performance at the end of both weeks for zopiclone. Critical flicker fusion was significantly increased in subjects on temazepam. There were no abnormalities for both zopiclone and temazepam subjects in the blood picture, renal profile, liver function, urine and ECG before and after the study. Zopiclone is an effective hypnotic comparable to temazepam.

Helicobacter pylori infection and non-ulcer dyspepsia: the effect of treatment with colloidal bismuth subcitrate

Goh KL, Parasakthi N, Peh SC, Wong NW, Lo YL, Puthucheary SD

Scand. J. Gastroenterol., 1991 Nov;26(11):1123-31.
PMID: 1754846

A study was undertaken to determine the role of Helicobacter pylori in non-ulcer dyspepsia (NUD) and to determine the efficacy of colloidal bismuth subcitrate (CBS) in the treatment of NUD. Seventy-one patients were randomly allocated (double blind) to CBS or placebo, two tablets twice daily for 4 weeks. The severity of dyspepsia was scored and endoscopies performed before and after treatment, and antral biopsy specimens were taken for bacteriologic and histologic examination. Forty patients had H. pylori infection, and all had changes of chronic active gastritis. H. pylori was cleared from 17 to 21 patients (81%) treated with CBS, whereas none of the 19 patients treated with placebo cleared the bacteria. Improvement in histology was noted in 15 of 21 patients (71.4%) treated with CBS, whereas no improvement was noted in any of the placebo controls. Thirty-one patients were negative for H. pylori. All had either normal gastric histology or minor degrees of inflammation. Seventeen of these patients received CBS, and 14 received placebo. All groups reported improvement in the symptom score; however, the H. pylori-positive, CBS-treated group recorded a significantly higher improvement than the other groups (p less than 0.001). Relapse of H. pylori infection after initial clearance of the bacteria was high. Twelve of 16 patients evaluated relapsed 1 month after withdrawal of CBS.

Fulltext Evaluation of therapies in the treatment of Helicobacter pylori associated non-ulcer dyspepsia

Nafeeza MI, Shahimi MM, Kudva MV, Ahmad H, Isa MR, Sood IM, et al.

Singapore Med J, 1992 Dec;33(6):570-4.
PMID: 1488663

This randomised double blind placebo controlled study evaluated the effectiveness of colloidal bismuth subcitrate (CBS), ampicillin and their combination in the treatment of Helicobacter Pylori in non-ulcer dyspepsia (NUD) and assessed if elimination of this organism is associated with improvement of gastritis and the symptoms. Forty-eight NUD patients with H. pylori and histologic gastritis were randomly allocated to one of the three regimens for 28 days. Symptoms were assessed before and after treatment. Forty-three patients completed the trial. Repeat endoscopy within 48 hours of completing treatment showed suppression of H. pylori in 6 of 7 patients (85.7%) on combined therapy and one of 8 patients (12.5%) on CBS therapy (p = 0.0205). There was no suppression of the bacteria in patients treated with ampicillin. Repeat endoscopy performed 2 weeks after completing treatment showed suppression of H. pylori in 3 of 7 patients (42.9%) on combined therapy and none in the other two groups. Patients on combined therapy who had suppression of H. pylori, 48 hours or 2 weeks after completing treatment were noted to have historical improvement of their gastritis (p = 0.0001 and p = 0.05 respectively). This was also associated with improvement of symptoms in these patients.

Treatment of subperiodic Brugia malayi infection with a single dose of ivermectin

Mak JW, Navaratnam V, Grewel JS, Mansor SM, Ambu S

Am J Trop Med Hyg, 1993 Apr;48(4):591-6.
PMID: 8480868

A clinical trial on the efficacy of a single oral dose of ivermectin at 20, 50, 100, and 200 micrograms/kg was carried out in 40 subjects with subperiodic Brugia malayi microfilaremia. There was no significant difference in the clearance of microfilaremia in the four treatment groups, and the lowest geometric mean microfilarial count (GMC) achieved in the 40 subjects was 8.8/ml or 8.3% of the initial count (106.1/ml), at two weeks post-treatment. The GMC started to increase at one month post-treatment and by six months was 22.2% of the initial GMC. Only 27.5%, 23.1%, 15.0%, and 18.9% of subjects were amicrofilaremic at two, four, 12, and 24 weeks post-treatment, respectively. Mild fever in 35% of the subjects was the primary side reaction and was more common in those with microfilarial counts > or = 500/ml (85.7%) than in those with counts < 500/ml (32%). The clearance of B. malayi microfilaremia by ivermectin was less rapid than that reported for Wuchereria bancrofti. The smaller number of side reactions encountered in the present study compared with those reported for bancroftian filariasis is probably related to the lower microfilarial density in the present subjects. Since ivermectin at a single oral dose of 20-200 micrograms/kg can reduce the GMC to less than 10% at two weeks and maintain it below 25% of the initial level even at six months post-treatment, it is recommended that the drug be seriously evaluated for use in the control of brugian filariasis.

Determination of naltrexone dosage for narcotic agonist blockade in detoxified Asian addicts

Navaratnam V, Jamaludin A, Raman N, Mohamed M, Mansor SM

Drug Alcohol Depend, 1994 Feb;34(3):231-6.
PMID: 8033761

Thirty-eight, adult, male, detoxified, Malaysian opiate addicts participated in this double-blind clinical evaluation of naltrexone. Addicts from three ethnic groups: Chinese, Malays, and Indians received a weekly regimen of naltrexone (100 mg on Days 1 and 3, and 150 mg on Day 5). Subjects were randomly assigned to receive intravenous challenge with either 25 mg heroin or placebo 12, 24, 48, and 72 h after the third naltrexone dose. Physiological and subjective parameters were measured at each challenge interval. Results indicated that naltrexone was effective in blocking the physiological and psychological effects of heroin for at least 48 and 72 h, respectively, in detoxified Malaysian opiate addicts. The efficacy of naltrexone did not differ among the three ethnic groups evaluated in this study.

Dietary palmitic acid results in lower serum cholesterol than does a lauric-myristic acid combination in normolipemic humans

Sundram K, Hayes KC, Siru OH

Am J Clin Nutr, 1994 Apr;59(4):841-6.
PMID: 8147328

In a double-blind crossover study, 17 normocholesterolemic male volunteers were fed carefully designed whole-food diets in which 5% of energy was exchanged between palmitic (16:0) and lauric + myristic acids (12:0 + 14:0) whereas all other fatty acids were held constant. Resident males received each diet during separate 4-wk periods. The test diets supplied approximately 30% of energy as fat and 200 mg cholesterol/d. Compared with the 12:0 + 14:0-rich diet, the 16:0-rich diet produced a 9% lower serum cholesterol concentration, reflected primarily by a lower (11%) low-density-lipoprotein-cholesterol concentration and, to a lesser extent, high-density-lipoprotein cholesterol. No diet-induced changes were noted in the cholesterol content of other lipoproteins, nor did exchange of saturated fatty acids affect the triglyceride concentration in serum or lipoprotein fractions. These data indicate that a dietary 12:0 + 14:0 combination produces a higher serum cholesterol concentration than does 16:0 in healthy normocholesterolemic young men fed a low-cholesterol diet.

Fulltext Phenylephrine eye drops in ophthalmic surgery--a clinical study on cardiovascular effects

Chin KW, Law NM, Chin MK

Med J Malaysia, 1994 Jun;49(2):158-63.
PMID: 8090095

Phenylephrine in concentrations of either 2.5% or 10% is widely used as a mydriatic agent in ophthalmic surgery. Its potential cardiovascular effects are seldom recorded as ophthalmic surgery is not usually monitored by an anaesthetist. A prospective randomised double blind study was carried out in 89 consecutive cases of uncomplicated cataract surgery in the presence of an anaesthesiologist ensuring the continuous monitoring of blood pressure, heart rate, electrocardiography and pulse oximetry. All these patients were given a drop of either normal saline, 2.5% or 10% phenylephrine in addition to mydriacyl prior to surgery. Blood pressure readings were found to be significantly higher in non-hypertensive patients receiving phenylephrine at the start of the operation and at five, 10, 15 and 20 minutes intra-operatively and the first three hours post-operatively. Blood pressure readings in hypertensive patients, on the other hand, were also found to increase after phenylephrine administration, though not statistically significant. 10.3% of the 10% phenylephrine group and 3% of the 2.5% phenylephrine group required intraoperative intravenous hypotensive agent to control the blood pressure. There were no arrhythmias or ischaemic changes observed intraoperatively. None of the patients complained of palpitation, headache or chest discomfort. There was no oxygen desaturation observed. We concluded that significant hypertensive effects can arise after phenylephrine eye drop administration. Hence, it should be used cautiously with intraoperative monitoring of the cardiovascular status during cataract surgery.

Omeprazole 40 mg o.m. combined with amoxycillin alone or with amoxycillin and metronidazole in the eradication of Helicobacter pylori

Goh KL, Peh SC, Parasakthi N, Wong NW, Tan KK, Lo YL

Am J Gastroenterol, 1994 Oct;89(10):1789-92.
PMID: 7942668

OBJECTIVES: Our objectives were to determine the effect of dual therapy with omeprazole and amoxicillin and of triple therapy with omeprazole, amoxicillin, and metronidazole in the eradication of Helicobacter pylori (HP) and to study the long-term results of eradication in these patients.
METHODS: A prospective, randomized, controlled trial was performed. Patients who were recruited had unequivocal evidence of HP infection based on culture, histology, rapid urease test, and Gram's stain of a tissue smear. Eradication was defined as the absence of bacteria in all tests performed on both corpus and antral biopsies.
RESULTS: The infection was eradicated in 15 of 19 (78.9%) patients randomized to receive dual therapy and in 19 of 22 (86.4%) patients who received triple therapy. We followed the course of 30 patients in whom HP had been eradicated for a prolonged term (up to 12 months). All remained clear of HP. Twenty-five of 28 patients (89.3%) with duodenal ulcers in whom HP was successfully eradicated remained healed at 12 months. Fewer side effects were reported among patients who received the dual therapy.
CONCLUSIONS: Combination therapy with omeprazole and amoxicillin with or without metronidazole is effective in the eradication of HP. In particular, the dual therapy regimen with amoxicillin is not only effective but is also well tolerated by patients.

Fulltext Efficacy and safety of loratadine compared with astemizole in Malaysian patients with allergic rhinitis

Lee ST, Amin MJ

Singapore Med J, 1994 Dec;35(6):591-4.
PMID: 7761882

Nonsedating selective peripheral H1 receptor antagonists are an important advance in antihistaminic therapy in allergic patients. This is a randomised, double-blind parallel group study comparing the use of two such agents viz loratadine 10mg daily and astemizole 10mg daily for two weeks in 39 Malaysian allergic rhinitis patients. At these dosages, both drugs were demonstrated to be efficacious (p < 0.05) for controlling nasal symptoms and safe in terms of short term biochemical and haematological changes and adverse effects noted. Evaluating efficacy criteria utilised in this study loratadine and astemizole were comparable but loratadine was significantly more effective in three areas viz: (i) in diminishing nasal symptoms after 2 weeks of treatment (p = 0.03); (ii) physician's efficacy evaluation after 2 weeks' treatment (p = 0.009); (iii) patient's efficacy evaluation after 2 weeks' treatment (p = 0.019).

Prevention of duodenal ulcer relapse with omeprazole 20 mg daily: a randomized double-blind, placebo-controlled study

Goh KL, Boonyapisit S, Lai KH, Chang R, Kang JY, Lam SK

J Gastroenterol Hepatol, 1995 1 1;10(1):92-7.
PMID: 7620115

We report the first double-blind, placebo-controlled study that assesses the efficacy and safety of omeprazole 20 mg daily in the maintenance treatment of duodenal ulcer. For the healing phase, 128 patients with endoscopically proven active duodenal ulcer and a history of three or more relapses during the 2 years prior to the study were treated until healing with omeprazole 40 mg daily for 2 and up to 8 weeks. One hundred and twenty-three patients whose ulcers were healed were randomized to receive omeprazole 20 mg daily (n = 60) or placebo (n = 63) for 12 months as maintenance treatment. Patients were interviewed at 3, 6, 9 and 12 months, and endoscopy was performed at 3, 6 and 12 months and whenever symptoms recurred. The healing rates of the 124 patients completing the healing phase were 84, 98 and 100% at 2, 4 and 8 weeks, respectively. During the maintenance phase, eight and four patients discontinued treatment from the omeprazole and placebo groups, respectively. The proportion of patients in remission in the omeprazole group and placebo group after 12 months were 94 and 9% respectively (life table estimates, P < 0.0001). No significant clinical or laboratory changes were observed in patients on therapy with omeprazole. Patients with a history of frequent relapses thus continued to have a very high relapse rate without prophylactic treatment. Omeprazole 20 mg daily was effective and safe in maintaining such patients in remission.

Intubation without muscle relaxant: an alternative technique for rapid tracheal intubation

Wong AK, Teoh GS

Anaesth Intensive Care, 1996 Apr;24(2):224-30.
PMID: 9133197

The quality of laryngoscopy and tracheal intubation with propofol augmented by alfentanil was investigated as an alternative technique for rapid tracheal intubation. 119 patients aged between 18 and 60 years (ASA 1 and 2) undergoing elective surgery were prospectively studied in a randomized double-blind controlled fashion. Tracheal intubation facilitated by suxamethonium 1.0 mg/kg alfentanil 15 mu g/kg alfentanil 30 mu g/kg or saline control was compared after propofol induction. The quality of laryngoscopy and intubation were graded according to jaw relaxation, ease of insertion of the endotracheal tube and coughing on intubation. Failure to intubate occurred in 4% and 17% with alfentanil 15 mu g/kg and saline control respectively Tracheal intubation was successful in all patients with alfentanil 30 mu g/kg and suxamethonium 1.0 mg/kg. Alfentanil 15 mu g/kg was not statistically significantly different from saline (P = 0.112). Alfentanil 30 mu g/kg provided similar overall intubating conditions (P = 0.5) to suxamethonium 1.0 mg/kg. Alfentanil in both dosages effectively attenuated the haemodynamic responses to laryngoscopy and tracheal intubation.

Effect of heparin-surface-modified poly(methyl methacrylate) intraocular lenses on the postoperative inflammation in an Asian population

Lai YK, Fan RF

J Cataract Refract Surg, 1996;22 Suppl 1:830-4.
PMID: 9279680

PURPOSE: To compare the efficacy of heparin-surface-modified (HSM), poly(methyl methacrylate) (PMMA) posterior chamber intraocular lenses (IOLs) with that of unmodified PMMA IOLs in reducing postoperative complications caused by inflammatory reactions after extracapsular cataract extraction in an Asian population.
SETTING: Departments of Ophthalmology, University of Malaya, Kuala Lumpur, Malaysia, and Tan Tock Seng Hospital, Singapore.
METHODS: In a randomized, double-blind study performed at two centers, 51 patients received an HSM PMMA lens and 48, an unmodified PMMA IOL. Cell and pigment deposits were evaluated by slitlamp at 1 to 6 days, 2 to 3 weeks, and 3 to 6 months postoperatively.
RESULTS: Significantly more eyes with unmodified IOLs had inflammatory cell deposits than those with HSM IOLs at 3 to 6 months (P < .001) and 12 to 14 months (P = .018) postoperatively. The HSM group also had significantly fewer cell deposits per patient at these two follow-ups. Significantly more eyes in the non-HSM group had pigment deposits 3 to 6 months after surgery (P = .049). One year postoperatively, about 85% of patients in both groups had a best corrected visual acuity of 0.5 or better.
CONCLUSION: Heparin surface modification significantly reduced the inflammatory response to PMMA IOLs in an Asian population for at least 12 to 14 months.

Trans (elaidic) fatty acids adversely affect the lipoprotein profile relative to specific saturated fatty acids in humans

Sundram K, Ismail A, Hayes KC, Jeyamalar R, Pathmanathan R

J Nutr, 1997 Mar;127(3):514S-520S.
PMID: 9082038

Although dietary trans fatty acids can affect plasma lipoproteins negatively in humans, no direct comparison with specific saturated fatty acids has been reported, even though trans fatty acids were designed to replace saturates in foods and food processing. In this study, dietary trans 18:1 [elaidic acid at 5.5% energy (en)] was specifically exchanged for cis 18:1, 16:0 or 12:0 + 14:0 in 27 male and female subjects consuming moderate fat (31% en), low cholesterol (<225 mg/d) whole food diets during 4-wk diet periods in a crossover design. The trans-rich fat significantly elevated total cholesterol and LDL cholesterol relative to the 16:0-rich and 18:1-rich fats and uniquely depressed HDL cholesterol relative to all of the fats tested. Trans fatty acids also elevated lipoprotein (a) [Lp(a)] values relative to all dietary treatments. Furthermore, identical effects on lipoproteins were elicited by 16:0 and cis 18:1 in these subjects. The current results suggest that elaidic acid, one of the principal trans isomers produced during industrial hydrogenation of edible oils, adversely affects plasma lipoproteins. Thus, the negative effect of elaidic acid on the lipoprotein profile of humans appears to be unmatched by any other natural fatty acid(s).

Combination amoxycillin and metronidazole with famotidine in the eradication of Helicobacter pylori--a randomized, double-blind comparison of a three times daily and twice daily regimen

Goh KL, Parasakthi N, Chuah SY, Toetsch M

Eur J Gastroenterol Hepatol, 1997 Nov;9(11):1091-5.
PMID: 9431900

OBJECTIVES: To determine the efficacy of a three times daily (t.i.d.) versus a twice daily (b.i.d.) regimen of combination amoxycillin and metronidazole and famotidine in the eradication of Helicobacter pylori and the influence of metronidazole resistance on the outcome of treatment.
PATIENTS: Patients selected had unequivocal evidence of H. pylori infection based on the urease test, culture and histology and had either peptic ulcer disease or non-ulcer dyspepsia.
DESIGN: The study was a comparative and double-blind study and patients were randomized to receive either amoxycillin 750 mg t.i.d. and metronidazole 500 mg t.i.d. for 12 days or amoxycillin 1000 mg b.i.d. and metronidazole 500 mg b.i.d. for 12 days. Both groups also received famotidine 40 mg for 6 weeks.
MAIN OUTCOME MEASURE: Patients were assessed for successful eradication, defined as absence of bacteria in all tests, at least 4 weeks after completion of antibiotic therapy by repeat gastroscopy.
RESULTS: One hundred and twenty-nine patients were recruited for the study. Two patients defaulted follow-up, two patients were withdrawn from the study and six patients were found to be non-compliant with medications. The eradication rates of the t.i.d. regimen was higher than the b.i.d. regimen (per protocol (PP) analysis: 83.3% (50/60) vs. 76.3% (45/59), P=0.337; intention-to-treat (ITT) analysis: 78.5% (51/65) vs. 75.0% (48/64), P=0.642). Seventy-five patients had pre-treatment cultures checked for metronidazole resistance, 33 (44.0%) were found to be resistant. Acquired resistance occurred in 3/40 (7.5%) patients. Eradication rates of metronidazole-sensitive and metronidazole-resistant patients: t.i.d. regimen - 100% (17/17) and 88.2% (15/17), b.i.d. regimen - 19/21 (90.5%) and 11/15 (73.3%). Side effects were reported in up to 70% of patients but were mild and tolerable in the majority. Two patients were withdrawn from the study because of a fixed drug eruption in one and generalized macular rash in the other.
CONCLUSION: Combination amoxycillin and metronidazole is effective in eradicating H. pylori. There was a tendency for the t.i.d. regimen to be better than the b.i.d. regimen and for metronidazole-resistant infections to be associated with a lower eradication rate but these differences did not reach statistical significance.

The effect of mivacurium pretreatment on intra-ocular pressure changes induced by suxamethonium

Chiu CL, Lang CC, Wong PK, Delilkan AE, Wang CY

Anaesthesia, 1998 May;53(5):501-5.
PMID: 9659028

Forty patients without eye disease, undergoing elective nonophthalmic surgery, were studied in a double-blind, randomised, placebo-controlled study evaluating the efficacy of mivacurium pretreatment in attenuating the rise in intra-ocular pressure in response to suxamethonium administration, laryngoscopy and intubation. The patients were randomly allocated to receive either mivacurium 0.02 mg.kg-1 or normal saline as pretreatment 3 min before a rapid sequence induction technique using alfentanil, propofol and suxamethonium. Suxamethonium induced a significant increase in intra-ocular pressure in the control group but not in the mivacurium pretreatment group (mean (SEM) increase = 3.5 (1.2) mmHg vs. 0.4 (0.8) mmHg, p < 0.05). There was a decrease in intra-ocular pressure in both groups after laryngoscopy and intubation with no significant difference between the two groups. These results show that mivacurium pretreatment is effective in preventing the increase in intra-ocular pressure after suxamethonium administration.
