RESUMO
BACKGROUND: Emergence agitation after maxillofacial surgeries is an anxious and problematic complication for the surgeon and anesthesiologist that may lead to self-extubation, haemorrhage, and surgical destruction. In this study, we investigated the effects of preemptive administration of diphenhydramine on emergence agitation and quality of recovery after maxillofacial surgery in adult patients. METHODS: Eighty-five patients undergoing maxillofacial surgery were randomized into two groups. The diphenhydramine group (Group D, n = 40) received diphenhydramine premedication 0.5 mg/kg before anesthesia induction, while the control group (Group C, n = 40) received volume-matched normal saline as a placebo. Before incision, all patients receive 0.1 mg/kg morphine sulfate slowly intravenously within 5 min. Continuous infusion of remifentanil 0.2 µg/kg/h and inhalation of isoflurane was maintained during the anesthesia period. Paracetamol 1 g was infused 15 min before extubation. We evaluated the incidence of agitation during the extubation period after general anesthesia, hemodynamic parameters, and recovery characteristics during the postoperative period. RESULTS: During extubation time, the incidence of emergence agitation was lower in Group D than in Group C (16% vs. 49%, P = 0.041). The time from isoflurane discontinuation to extubation (7.7 min in Group D vs. 6.8 min in Group C, P = 0.082) was not different. Grade of cough during emergence, the severity of pain, analgesic requirements, and hemodynamic changes were lower in group D compared with Group C. CONCLUSIONS: Preemptive administration of diphenhydramine provided smooth emergence from anesthesia. It also improved the quality of recovery after maxillofacial surgery.

INTRODUCTION: Nasogastric tube (NGT) insertion is sometimes required in intubated patients. NGTs are prone to kink and coil during blind insertion. We hypothesised that wire rope guide-assisted NGT insertion with chin lift can significantly improve the first-attempt success rate over the conventional technique during its insertion in intubated patients. OBJECTIVE: Mean time to successful insertion of NGT, the failure rate of NGT insertion in the first attempt, the failure rate of NGT insertion in the second attempt and overall failure rate were assessed along with the incidence of any complications. METHOD: This prospective clinical trial conducted 100 adult patients presenting for abdominal surgery under general anaesthesia. These patients were randomised to an experimental technique of Wire rope guide with chin lift (wire group) or a control technique of head flexion (control group) for insertion of the NGT. RESULTS: The first-attempt success rate was 98% in wire group compared with 74% in the control group (P = .001). Thus, the first-attempt failure rate was 2% in wire group compared with 26% in the control group (P = .001). The median time required to insert the NGT was significantly shorter in wire group (35.3 ± 4.8 vs 61.5 ± 6.2 seconds, P = .001). The incidences of kinking/coiling, bleeding, and moderate injuries were significantly lower in wire group. CONCLUSION: The use of rope wire guide for correct positioning of the NGT in intubated patients is less time-consuming with the high first-attempt success rate and lower incidence of procedure-related injuries compared to the conventional method.

PURPOSE: To evaluate the efficacy of single low dose (75 mg) preoperative pregabalin in reducing post-operative pain of septorhinoplasty. METHODS: A double blind single center Randomized controlled trial based on block randomization. In the pregabalin group (PG) 34 participants received 75 mg pregabalin orally one hour before anesthesia induction while in control group (CG) 34 participants received a placebo. Pain and sedation were repeatedly measured with Visual Analouge Scale (VAS) and Riker Sedation-Agitation Scale (RSAS) respectively, 0.5, 1, 2, 6, 24 hours postextubation. Cumulative doses of fentanyl and ibuprofen received in both groups were compared. RESULTS: Thirty-two of the participants in PG and 33 of the participants in CG completed the study. The Mean VAS pain score was less in PG versus CG 30 min postoperatively (2.30 ± 1.30 vs. 4.85 ± 1.17), one hour (2.28 ± 0.92 vs. 4.27 ± 0.78), two hours (2.11 ± 0.88 vs. 3.60 ± 0.61) and six hours (1.47 0.62 vs. 2.76 ± 0.91) but not 24-hours postoperatively (0.84 ± 0.62 vs. 1.09 ± 0.92). Participants in the PG were less agitated during early post-extubation period (at 10 min: RSAS 3.93 ± 0.43 vs. 4.42 ± 0.50) and more alert during the first hour post-extubation (at 60 min: RSAS 3.90 ± 0.29 vs. 3.36 ± 0.69). The total dose of rescue fentanyl and ibuprofen was lower in the PG compared to the CG. CONCLUSIONS: A single dose of 75 mg pregabalin is very effective for pain control after septorhinoplasty procedure when administered one hour before anesthesia induction. Side effects are rare and opioid sparing was noted. TRIAL REGISTRATION: Clinical trial number: IRCT2017043033706N1.

BACKGROUND: The incidence of difficult laryngoscopy is reported in the range of 1.5% to 20%. We hypothesized that there is a close association between the occurrence of difficult laryngoscopy and the height between the anterior borders of the mentum and thyroid cartilage, while the patient lies supine with her/his mouth closed. We have termed this the "thyromental height test" (TMHT). Our aim in this study was to determine its utility in predicting difficult laryngoscopy. METHODS: Three hundred fourteen consecutive male and female patients aged ≥ 16 years scheduled to undergo general anesthesia were invited to participate. Airway assessments were performed with the modified Mallampati test, thyromental distance and sternomental distance, and TMHT in the preoperative clinic. Afterward, Cormack and Lehane grade of laryngoscopy views was assessed during intubation. The laryngoscopist was unaware of airway assessments. As a primary end point, the validity and prediction indexes for the TMHT were calculated. Calculation of validity indexes for the 3 other methods of airway assessment was a secondary objective of this study. RESULTS: The optimal sensitivity and specificity values were in the range of 47.46 to 51.02 mm. To facilitate clinical application, a cutoff value equal to 50 mm was chosen. TMHT was more accurate than the other tests (all P < 0.0001). CONCLUSIONS: The TMHT appears to be a more accurate predictor of difficult laryngoscopy than the existing anatomical measurements.

BACKGROUND: Tissue injuries may provoke neuro-hormonal response which in turn may lead to release of inflammatory cytokines. We hypothesize that block of afferent sensory pathways by infiltration of 0.5% bupivacaine in the scalp may decrease neuro-hormonal response in the neurosurgical patient. METHODS: After obtaining informed consent, forty ASA physical statuses I, II, or III patients between the ages of 18 and 65 years were enrolled randomly into two equal groups to receive either 20 ml of 0.5% bupivacaine (group A) or 20 ml of 0.9% normal saline as a placebo (group B) in the site of pin insertion and scalp incision. As the primary outcome we checked serum C-reactive protein (CRP) levels before implementation of noxious stimulus, 24h, and 48h after the end of surgery to compare these values between groups. In addition, mean arterial pressure (MAP) and heart rate (HR) were checked at baseline (after the induction of anesthesia), one minute after pin fixation and 5, 10, and 15 minute after skin incision and the recorded values were compared between groups. RESULTS: No significant difference was found between serum CRP levels of the two groups. Comparison of mean HR between groups shows no significant difference. The mean of MAP was significantly lower in the group A in comparison with the group B (p< 0.001). CONCLUSION: The results of this study confirm that 0.5% bupivacaine scalp infiltration before skull-pin holder fixation and skin incision could not decrease post-operative C-reactive protein level.
RESUMO
BACKGROUND: Recently, several studies have been conducted to determine the optimal strategy for intra-operative fluid replacement therapy in renal transplantation surgery. Since infusion of sodium bicarbonate as a buffer seems to be safer than other buffer compounds (lactate, gluconate, acetate)that indirectly convert into it within the liver, We hypothesized tight control of metabolic acidosis by infusion of sodium bicarbonate may improve early post-operative renal function in renal transplant recipients. METHODS: 120 patients were randomly divided into two equal groups. In group A, bicarbonate was infused intra-operatively according to Base Excess (BE) measurements to achieve the normal values of BE (-5 to +5 mEq/L). In group B, infusion of bicarbonate was allowed only in case of severe metabolic acidosis (BE ≤ -15 mEq/L or bicarbonate ≤ 10 mEq/L or PH ≤ 7.15). Minute ventilation was adjusted to keep PaCO2 within the normal range. Primary end-point was sampling of serum creatinine level in first, second, third and seventh post-operative days for statistical comparison between groups. Secondary objectives were comparison of cumulative urine volumes in the first 24 h of post-operative period and serum BUN levels which were obtained in first, second, third and seventh post-operative days. RESULTS: In group A, all of consecutive serum creatinine levels were significantly lower in comparison with group B. With regard to secondary outcomes, no significant difference between groups was observed. CONCLUSION: Intra-operative tight control of metabolic acidosis by infusion of Sodium Bicarbonate in renal transplant recipients may improve early post-operative renal function.
RESUMO
INTRODUCTION: There is a large armamentarium of pain-reducing interventions and analgesic choices available to anesthesiologists, but oligoanalgesia continues to be a large problem. We studied the attitudes of residents and faculty members of anesthesiology towards different domains of pain medicine. METHODS: anonymous questionnaires were mailed to 68 professionals containing demographic and personal data plus 40 items in 10 domains: control, emotion, disability, solicitude, cure, opioids, harm, practice settings, training, and barriers. Internal consistency was 0.70 and the test-retest reliability was 0.80. RESULTS: With 81% response rate, we observed desirable beliefs towards all domains except moderately undesirable beliefs towards the domain solicitude. Scores of residents and faculties were not significantly different. CONCLUSION: Continuing education programs on both the international guidelines, routine professional education, are needed to improve attitudes towards pain control.

PURPOSE: Postoperative nausea and vomiting (PONV) and pain following bariatric surgery are problematic and affect the outcome of patients. Intraoperative multimodal antiemetic prophylaxis is essential to improve postoperative outcomes. This study investigated the effect of adding diphenhydramine to acetaminophen and ondansetron in reducing postoperative nausea and vomiting and pain following laparoscopic sleeve gastrectomy (LSG). MATERIALS AND METHODS: Eighty-two patients scheduled for LSG were assigned to receive a single preinduction dose of diphenhydramine 0.4 mg/kg VI (D group) in addition to acetaminophen 1g and ondansetron 4 mg IV at the end of surgery and just acetaminophen 1 g and ondansetron 4 mg IV (C group) in a randomized, double-blind trial. PONV was assessed in recovery and 24 hours after surgery in the ward. Postoperative pain, analgesic requirements, and patients' level of sedation were also assessed. RESULTS: The PONV rates in the recovery of the D group and the C group were 30% and 56% (P = .001). It also had a more significant reduction in the D group than in the C group in the first 24 h after surgery (40% vs. 66%). The severity of pain score and level of sedation and analgesic requirements was significantly reduced in this period in the D group. CONCLUSION: Prophylactic diphenhydramine 0.4 mg/kg at the induction of general anesthesia in combination with acetaminophen 1 g and ondansetron 4 mg at the end of surgery reduced the incidence of PONV and postoperative severity of pain in laparoscopic sleeve gastrectomy.

Background: Goal-directed fluid therapy (GDFT) is a new concept to describe the cardiac output (CO) and stroke volume variation to guide intravenous fluid administration during surgery. LiDCOrapid (LiDCO, Cardiac Sensor System, UK Company Regd 2736561, VAT Regd 672475708) is a minimally invasive monitor that estimates the responsiveness of CO versus fluid infusion. We intend to find whether GDFT using the LiDCOrapid system can decrease the volume of intraoperative fluid therapy and facilitate recovery in patients undergoing posterior fusion spine surgeries in comparison to regular fluid therapy. Methods: This study is a randomised clinical trial, and the design was parallel. Inclusion criteria for participants in this study were patients with comorbidities such as diabetes mellitus, hypertension, and ischemic heart disease undergoing spine surgery; exclusion criteria were patients with irregular heart rhythm or severe valvular heart disease. Forty patients with a previous history of medical comorbidities undergoing spine surgery were randomly and evenly assigned to receive either LiDCOrapid guided fluid therapy or regular fluid therapy. The volume of infused fluid was the primary outcome. The amount of bleeding, number of patients who needed packed red blood cell transfusion, base deficit, urine output, days of hospital length of stay and intensive care unit (ICU) admission, and time needed to start eating solids were monitored as secondary outcomes. Results: The volume of infused crystalloid and urinary output in the LiDCO group was significantly lower than that of the control group (p = .001). Base deficit at the end of surgery was significantly better in the LiDCO group (p < .001). The duration of hospital length of stay in the LiDCO group was significantly shorter (p = .027), but the duration of ICU admission was not significantly different between the two groups. Conclusion: Goal-directed fluid therapy using the LiDCOrapid system reduced the volume of intraoperative fluid therapy.
RESUMO
BACKGROUND: The prognostic factors of long-term outcomes in hospitalized patients with diabetes mellitus and COVID-19 are lacking. METHODS: In this retrospective cohort study, we evaluated patients aged ≥ 18-years-old with the COVID-19 diagnosis who were hospitalized between Feb 20 and Oct 29, 2020, in the Sina Hospital, Tehran, Iran. 1323 patients with COVID-19 entered in the final analysis, of whom 393 (29.7%) patients had diabetes. We followed up patients for incurring in-hospital death, severe COVID-19, in-hospital complications, and 7-month all-cause mortality. By doing univariate analysis, variables with unadjusted P-value < 0.1 in univariate analyses were regarded as the confounders to include in the logistic regression models. We made adjustments for possible clinical (model 1) and both clinical and laboratory (model 2) confounders. RESULTS: After multivariable regression, it was revealed that preadmission use of sulfonylureas was associated with a borderline increased risk of severity in both models [model 1, OR (95% CI):1.83 (0.91-3.71), P-value: 0.092; model 2, 2.05 (0.87-4.79), P-value: 0.099] and major adverse events (MAE: each of the severe COVID-19, multi-organ damage, or in-hospital mortality) in model 1 [OR (95% CI): 1.86 (0.90-3.87), P-value: 0.094]. Preadmission use of ACEIs/ARBs was associated with borderline increased risk of MAE in the only model 1 [OR (95% CI):1.83 (0.96-3.48), P-value: 0.066]. CONCLUSIONS: Preadmission use of sulfonylureas and ACEIs/ARBs were associated with borderline increased risk of in-hospital adverse outcomes.

RESUMO
BACKGROUND: The GlideScope (Saturn Biomedical Systems, B.C., Canada) is a reusable videolaryngoscope and is considered an effective device for tracheal intubation. We designed this study to evaluate the application of this device in nasogastric tube (NGT) insertion. METHODS: This randomized clinical trial was performed at a teaching hospital on 80 adult patients who required intraoperative placement of an NGT. The patients were divided into 2 groups (the control and the GlideScope group) using computerized, random allocation software. In the control group, the NGT was inserted blindly as commonly performed in operating rooms; however, in the GlideScope group, the tube was inserted with the assistance of a GlideScope. The number of attempts for NGT insertion and the time required for inserting the NGT properly along with the occurrence of possible complications were recorded. RESULTS: The mean intubation time in the GlideScope group was 27.7 +/- 20.7 s shorter than that in the control group. NGT insertion in the first attempt was successful in approximately 85% of the patients in the GlideScope group; in the control group, however, the tubes were inserted successfully after the first attempt in 57.5% of the patients. Complications were reported in 14 patients (35%) of the control group and 8 patients (20%) of the GlideScope group. CONCLUSION: GlideScope facilitates NGT insertion and reduces the duration of the procedure.

BACKGROUND: The present study was designed to describe the characteristics, risk factors and prognosis of patients diagnosed with CVT in our center. METHOD: The present retrospective cross-sectional study was conducted on patients diagnosed with cerebral vein or sinus thrombosis based on the patients' clinical presentation and the findings of the imaging studies between 2003 and 2008. The patients were studied for possible risk factors and the resultant outcome after terminating the therapeutic course. RESULTS: Headache, the most common symptom reported in 80% of the cases, was considered the first symptom in only 46% of these patients. Coma, focal motor deficit at presentation, hemorrhagic conversion of infarction and thrombosis in more than one sinus were factors associated with unfavorable outcome in these patients. CONCLUSION: Physicians should always have CVT in mind while examining patients particularly women on pills who complain about headache. More studies however are needed to point out more specific presentations which would lead to the early diagnosis of CVT in the patients.

PURPOSE: The aim of this study is to compare the effects of Sanosil and glutaraldehyde 2 percent in disinfecting ventilator connecting tubes in an intensive care unit (ICU) environment. DESIGN/METHODOLOGY/APPROACH: The 12-week open-labelled clinical trial was conducted in the surgical ICU of a teaching hospital from March to May 2005. In the first phase of the study, high level disinfection was performed using glutaraldehyde 2 percent, whereas Sanosil was used as the disinfectant agent of the second phase. Samples for microbial culture were obtained from the Y piece, the expiratory limb proximal to the ventilator and the humidifier in different stages; the results were then compared. FINDINGS: Positive culture was more frequently reported in Y pieces, humidifiers and expiratory end of ventilators. Comparing the two groups, there were more positive cultures in the glutaraldehyde group (p value = 0.005); multiple organism growths, gram negative, gram positive and fungi were also more frequent in this group (p value = 0.01; 0. 007; 0. 062; 0.144, respectively). ORIGINALITY/VALUE: The paper shows that Sanosil is an effective agent in reducing the contamination risk in the tubes used in ICUs.

OBJECTIVES: Normal saline is the most common crystalloid solution that is used in renal transplant surgery. In this study, our aim was to determine the effects of a combination of half saline and bicarbonate versus normal saline as a routine solution. MATERIALS AND METHODS: For this double-blind random-ized clinical trial, we enrolled 100 adult patients undergoing kidney transplant. Patients were divided into 2 groups: those who received normal saline and those who received half saline and bicarbonate infusion as fluid replacement therapy during renal transplant. All patients received about 40 mL/kg of crystalloids during surgery. Serial creatinine con-centrations (primary outcomes) were compared between groups at 1, 2, 3, and 7 days after surgery. Urine output (secondary outcome) was compared between groups at recovery and at 6 and 24 hours after surgery. In addition, base excess, chloride, and sodium levels were measured before and 6 hours after surgery. Each liter of half saline-bircarbonate, which is relatively isoosmotic to human plasma, was composed of 70 mEq bicarbonate, 77 mEq chloride, and 147 mEq sodium. RESULTS: Patients who received half saline-bicarbonate had significantly lower postoperative creatinine levels at all time points than patients who received normal saline (P = .019). Serum chloride and sodium levels (P = .001) were significantly higher and base excess (P = .007) was significantly lower in the normal saline group at 6 hours after transplant. At all time points, urine output levels were significantly higher in the half saline-bicarbonate group (P = .001). CONCLUSIONS: The use of half saline-bicarbonate was associated with better early graft function compared with normal saline in the first 7 days after transplant.

BACKGROUND: Recently, the peripheral anesthetic effect of tramadol has been the theme of many studies. The postoperative analgesic effects of subcutaneous wound infiltration with tramadol have not been extensively studied and compared with those of intravenous administration. OBJECTIVE: To compare the therapeutic effects and complications of intravenous versus local wound infiltration of using tramadol following pyelolithotomy. METHODS: This double-blind study was carried out on 60 patients (age 18-60 y) of American Society of Anesthesiologists physical status I-II who were awaiting pyelolithotomy in Sina Hospital, Tehran, Iran, during 2006 and 2007. They were randomly assigned to receive intravenous or subcutaneous wound infiltration with tramadol. Vital signs, the intensity of pain (visual analog scale), and the level of consciousness (Ramsey Sedation Scale [RSS]), as well as the frequency of nausea and vomiting were recorded during 30 minutes to 1 hour after the patient entered the recovery room. Vital signs were also recorded every hour until 6 hours postoperatively and then on the day after the patient was transferred to the ward. RESULTS: The RSS was lower in patients who had received subcutaneous infiltration of tramadol (p < 0.001). A significant difference was noted in the severity of pain between the groups; it was higher in the group that received intravenous tramadol. The average time for the first meperidine requirement was 45.2 +/- 8.4 min (mean +/- SD) in the subcutaneous group and 21.6 +/- 12.4 min in the intravenous group. Total meperidine consumption was lower in patients who had received subcutaneous wound infiltration with tramadol compared with those who had received intravenous tramadol (p < 0.001). Nausea and vomiting were more frequent during the first hour of recovery; the complication, however, was less frequent in the subcutaneous group. CONCLUSIONS: Subcutaneous wound infiltration with tramadol reduces postoperative opioid consumption and produces less nausea and vomiting than does intravenous administration.

BACKGROUND: General anesthesia and regional anesthesia have both been shown to be suitable techniques for patients undergoing lower thoracic and lumbar spine surgery; however, GA is the most frequently used method. The purpose of this study was to conduct an acceptable RCT to compare the intraoperative parameters and postoperative outcome after SA and GA in patients undergoing elective lumbar disk surgery. METHODS: Patients undergoing laminectomy for herniated lumbar disk during the years 2005 and 2007 were enrolled. They were randomly selected to undergo GA and SA. The variables recorded during the operation were the patients' HR, MAP, amount of blood loss, and surgeons' satisfaction with the operating conditions. The severity of pain, nausea, vomiting, and length of stay in the hospital were recorded in the postoperative course. RESULTS: The mean blood loss was less in the group undergoing GA; however, the difference was not statistically significant. The surgeon's satisfaction was reported to be higher in the GA group. No major intraoperative complication was reported in either series. During the recovery period, hypertension was reported to happen more frequently in the patients undergoing GA; and postoperative nausea and vomiting were more frequent among patients recovering from SA. CONCLUSION: Contrary to previous studies, the findings of the present study revealed that SA has no advantages over GA. Moreover, it was showed that GA can reduce the related risks and complications in several aspects.

OBJECTIVES: Catheterization of urinary bladder during surgery frequently leads to agitation of the patient in the recovery room, especially in those patients who remain catheterized after gaining consciousness. We hypothesized that administration of a combination of ketamine-haloperidol (KH) before urinary catheterization would reduce the incidence of catheter-related bladder discomfort (CRBD) while reducing some adverse effects of ketamine in the postoperative period. METHODS: A total of 119 male patients who underwent lumbar spinal stenosis surgery were randomized into three groups. The KH group consisted of 39 patients who received KH just before urinary catheterization. The second arm of the study including 40 patients who received pethidine-haloperidol (PH). The control (C) group consisted of 40 patients who received normal saline as a placebo. We sought to determine the incidence and severity of CRBD at arrival in recovery and one, six, and 24 hours after. RESULTS: The incidence of CRBD upon arrival in the recovery room was 17.9% in the KH group, and 52.5% and 55% in the PH and C groups, respectively. The incidence of CRBD was signiï¬cantly lower in the KH group at arrival in the recovery room. The severity of CRBD was lower in the KH group at one and six hours of surgery (p < 0.007). There was no significant difference 24 hours after surgery. CONCLUSIONS: Intravenous administration of KH before urinary catheterization effectively decreases the incidence and severity of postoperative CRBD while reducing adverse effects attributed to ketamine.
RESUMO
OBJECTIVES: Absorption of the fluid used for bladder irrigation during transurethral resection of prostate (TURP) may disturb the circulatory system and lead to clinical symptoms known as the transurethral resection syndrome. The purpose of this study was to evaluate the changes in electrolytes in patients who had undergone TURP. METHODS: For all the cases with benign prostatic hypertrophy enrolled in the present study, TURP was performed as recommended in Miller's Anesthesia, the sixth edition. Sterile water was used as an irrigating fluid for bladder washing. Laboratory tests were performed before and immediately after the surgery. RESULTS: No statistically significant changes were reported in the serum sodium, blood urea nitrogen, creatinine, and hematocrit. The most common complications were hypotension (8.3%), hypertension (7.8%), nausea (6.4%), and vomiting (2.8%). Hyponatremia, decreased hematocrit, and increased blood urea nitrogen/creatinine were rarely reported (2.5, 1.0, and 0.9%, respectively). CONCLUSION: Sterile water has been shown to be a safe irrigating fluid for TURP.
