Abstract
Background: Anal surgeries are prevalent, but they didn't perform as outpatient surgeries because of concerns about postoperative pain. The aim of the present study was to compare the effects of rectal acetaminophen and diclofenac on postoperative analgesia after anal surgeries in adult patients.
Methods: In a randomized, double-blinded, placebo-controlled study 60 ASA class I or II scheduled for haemorrhoidectomy, anal fissure or fistula repair, were randomized (with block randomization method) to receive either a single dose of 650 mg rectal acetaminophen (n=20), 100 mg rectal diclofenac (n=20) or placebo suppositories (n=20) after the operation. The severity of pain, time to first request of analgesic agent after administration of suppositories and complications were compared between three groups. Pain scores were evaluated in patients by Visual Analogue Scale (VAS) in 0 (after complete consciousness in recovery), 2, 4, 12 and 24 hours after surgery. The period between administration of the suppositories and the patients' first request to receive analgesic was compared between groups.
Results: Pain scores were lower significantly in rectal diclofenac than the other groups. The period between administration of the suppositories and the patients' first request to receive analgesic in diclofenac group was 219±73 minutes, was significantly longer compared with placebo (153±47 minutes) and acetaminophen (178±64 minutes) groups. No complications were reported.
Conclusions: Diclofenac suppository is more effective than acetaminophen suppository in post hemorrhoidectomy pain management.

Abstract
Background: The incidence of Patent Ductus Arteriosus (PDA) in premature infants whose birth weight is less than 1500 grams is approximately 30-60%, most of them need medical or surgical interventions. The purpose of this study is to determine the efficacy of prophylactic treatment with oral paracetamol (Acetaminophen- Hakim® Oral Drops 100 mg/ml, Hakim Pharmaceutical Co., Tehran, Iran) for PDA in preterm infants.
Methods: A randomized clinical trial conducted from March 2012 to March 2013. Thirty-two preterm newborns whose gestational age was under 32 weeks and birth weight was 1500 grams or less, admitted in neonatal intensive care unit (NICU) of Vali-Asr Hospital, Tehran were studied prospectively. They were randomly assigned in two groups. The prophylaxis group received oral paracetamol for a period of two days starting during first 24 hours of life. No placebo was given to the control group. Echocardiography was performed 24-36 hours after the last given dose in prophylaxis group and on the 4th and 5th day in control group. A p-value less than 0.05 are considered significant.
Results: There were 16 newborns in each group (20 boys and 12 girls). In 12 newborns of prophylaxis group the ductus arteriosus was closed although in control group in 8 newborns the duct was closed. No significant difference was observed in sex, gestational age, birth weight, mode of delivery, multifetal gestation and birth order between two groups. The rate of ductal closure was 75% and 50% in prophylaxis group and control group respectively (P=0.27).
Conclusion: Our study demonstrated that prophylactic paracetamol is ineffective in PDA closure, although the rate of ductal closure between two groups seems remarkable. Paracetamol as a new strategy for PDA closure because of cost effectiveness and harmlessness may be used in future. However, we presume larger sample size studies are needed to show the efficacy of paracetamol, side effects, and complications in PDA prophylaxis treatment.

Abstract
Background: Pain control after orthognathic surgeries due to severity of pain and limitations of opioids use in these patients are particular importance. The aim of this study was to evaluate the effect of oral gabapentin and intramuscular ketorolac in combination with intravenous acetaminophen for pain control after this surgery.
Methods: This study was a randomized clinical trial (RCT) on 75 patients (18-60 years old American Society of Anesthesiologists (ASA) physical status classification system, I, II) that undergo orthognathic surgery in Sina University Hospital, Tehran University of Medical Sciences, Tehran, Iran from June 2013 to August 2014. The patients were randomly divided in 3 groups. All of groups received 1 gr (intravenous acetaminophen) 30 minutes before the end of surgery. The control group (n= 25) received placebo. The second group (n= 25) received 30 mg ketorolac intramuscular after induction of anesthesia and the third group (n= 25) received 600 mg Gabapentin orally 30 minute before the induction of anesthesia. The pain severity score assessed by visual analogue scale (VAS), the level of sedation assessed by Ramsey scale, opioid requirement, nausea and vomiting was recorded in the post-anesthesia care unit (PACU) at 1, 3, 6, 12 and 24 hours after surgery. For rescue pain management intravenous morphine was administered.
Results: Seventy-five patients were enrolled in this study. Use of Ketorolac and gabapentin declines the pain intensity, level of agitation and morphine requirement in the recovery room and early hours in the ward (P= 0.011). The 24-hour opioid consumption, nausea and vomiting was significantly higher in control group compared with the both intervention groups (15±1.4 vs. 5±0.5 mg) (P< 0.05) retrospectively. Mean arterial pressure and heart rate changes was significantly lower in ketorolac and gabapentin groups compare to control group in recovery room (P< 0.05).
Conclusion: The result of this study suggest that ketorolac as well as gabapentin can decline the pain intensity and opioid requirement with less nausea and vomiting and good hemodynamic control after orthognathic surgery.

Abstract
Background: Previous studies have considered patent ductus arteriosus (PDA) a common finding in premature infants, leading to complications such as intracranial hemorrhage, necrotizing enterocolitis and pulmonary dysplasia. The aim of this study was to assess and compare the efficacy of oral ibuprofen and intravenous acetaminophen in the closure of arterial duct in premature newborns. We also evaluated the complications of each drug.
Methods: A cross-sectional and analytical study was conducted at Amiralmomenin Hospital, Semnan City in Iran from April 2012 to December 2017. Subjects were selected through convenient sampling and consisted of all premature infants with patent arterial duct. All of the infants with the diagnosis of PDA were treated with either intravenous acetaminophen or oral ibuprofen. Cardiac echocardiographic findings were assessed in two study groups before and after each treatment course. The complications associated with the two treatment approaches were evaluated in two groups after treatment of each drug.
Results: In general, twenty-four neonates (62.5% females) with the average gestational age of 31.46±3.43 weeks were studied. There was no significant difference in the echocardiographic characteristics in the two treatment groups at the pre and post-treatment periods as well as the side effects of the medications. The average number of treatment cycles in newborns treated with oral ibuprofen (1.06±0.25) was not significantly different compared to those with intravenous acetaminophen (1.25±0.46) (P=0.190). There was no significant difference concerning closure status of the arterial duct in the two treatment groups at the end of the first period (P=0.112) as well as after the second period of treatment (P=0.386).
Conclusion: Our study indicated similar efficacy of oral ibuprofen and intravenous acetaminophen in the closure of the arterial duct. The incidence of complications was not significantly different between the two groups. The results of this study suggest the use of intravenous acetaminophen as a suitable drug for PDA closure, particularly in cases of ibuprofen contraindications.

Abstract
Background: This study aimed to evaluate the effect of intravenous Ibuprofen Apotel analgesia in comparison with intravenous Morphine alone regimen in patients undergoing lubmar disc surgery.
Methods: This study was a double-blind clinical trial that was performed on patients with moderate to severe lumbar disc pain (VAS score or Visual analog scale more than 4) in August 2019 at Shohada Tajrish hospital. Patients in the Ibuprofen-Apotel group (group A) recieved intravenous Ibuprofen (800 mg) in 100 cc Normal saline in the first 30 minutes of Recovery, then 400 mg in 100 cc Normal saline every 6 hours (48 hours after surgery), plus 30 mg Apotel for each kilogram in100 cc Normal saline in 15 minutes every 8 hours. In group B, Morphine has injected with 70 µg/kg bolus and then 20µg/kg/h infused with a PCA pump with a Maximum Rate of 1mg/hr. Then 60 minutes after surgery, patients' pain was measured using an analog scale.
The primary outcome was defined as a reduction in pain intensity of 3 or more VAS units (which was considered as therapeutic success) and the incidence of side effects was considered as secondary outcomes.
Results: Based on the results of this study, the mean age of the subjects was 33.28±12.48 years. Also, the mean age in the group of Ibuprofen-Apotel and Morphine alone were 35.4±13.6 and 31.16±11.75 years. So, there is not a significant difference between the groups. 77.14% of the subjects (54 people) were male and 22.86% (16 people) were women. In comparing the frequency distribution of individuals in terms of gender and the method of creating analgesia, no significant difference was observed between the groups studied.
According to the results, after the intervention, the highest pain intensity in both groups was significantly decreased. However, no significant difference was observed between the two groups.
Conclusion: The study indicated that Ibuprofen can be effective in controlling postoperative pain.
