Early clinical experience with a new video laryngoscope (SANYAR®) for tracheal intubation in adults: a comparison clinical study
Objective: SANYAR® video laryngoscope (S-VL) is a new video laryngoscope. We conducted a comparative clinical study to assess its ability to provide laryngeal exposure and facilitate endotrachetal intubation (ETI) in adult patients. Methods: This comparison clinical study was conducted on adult patients undergoing elective general anesthesia. The patients were randomly divided into two groups of direct laryngoscopy (DL) or S-VL. The primary outcome was the time required for performing ETI. The glottic view and successful ETI on the first attempt was also compared between the two groups. Results: Full and partial glottic visualization was achieved in 100% of the patients in the S-VL group, while the corresponding figure in the DL group was 90%. Cormack-Lehane III was observed in 5 patients of the DL group, and ETI was successfully carried out with S-VL. The first-pass success rate of ETI was significantly higher in S-VL group compared to the DL group (94% vs. 78%; P = 0.034). The mean times to ETI were 38.32±6.4 and 35.31±8.4 seconds in DL and S-VL groups, respectively (P = 0.650). Conclusions: During ETI for general anesthesia, SANYAR® video laryngoscope compared with direct laryngoscopy improved glottic visualization and first-pass ETI rate
Porównanie wpływu leczenia metforminą i insuliną na kontrolę glikemii u krytycznie chorych pacjentów
Introduction: It is accepted that preventing hyperglycaemia during critical illness while assuring adequate caloric intake can reduce mortality
and morbidity. The aim of this study was to compare the metabolic effects of metformin and insulin on hyperglycaemia in ICU patients.
Methods: This double-blind randomised clinical trial was performed on 24 patients who were admitted to the intensive care unit (ICU)
from 20 March to 20 September 2007. All patients with serious injuries or with major non-abdominal surgeries were included if they met
the inclusion criteria, and were assigned randomly to one of the study groups. Patients in Group 1 received intensive insulin therapy, and
patients in Group 2 were treated with metformin. Moreover, the Acute Physiology And Chronic Health Evaluation (APACHE) II scoring
system was used to grade disease severity.
Results: Both glycaemic management protocols led to significantly improved glucose levels without any report of hypoglycaemia. The
mean initial glucose levels for the insulin group decreased significantly after the intravenous infusion of insulin (p < 0.001). Additionally,
the blood glucose concentration was significantly lower after two weeks of metformin administration compared to baseline measurements
(p < 0.001). Moreover, the blood glucose concentration decrease during these two weeks was significantly higher in the insulin group
(p = 0.01). Besides, APACHE II score was lower than baseline at the end of the study for both therapeutic groups (score of 10 vs. 15 [insulin]
and 16 [metformin]). Finally, new renal dysfunction (maximum serum creatinine level at least double the initial value) was observed in
three of the patients (two patients from the metformin group and one from the insulin group) in the last days of the protocol, although
none of the patients showed lactic acidosis after ICU admission.
Conclusions: Both metformin and intensive insulin therapy significantly decreased hyperglycaemia in ICU patients. Insulin caused
a greater reduction in blood glucose concentration but required more attention and trained personnel.Wstęp: Dowody naukowe wskazują, że zapobieganie hiperglikemii u osób w stanie krytycznym przy zapewnieniu odpowiedniego poboru
kalorii może zmniejszyć śmiertelność i chorobowość. Celem niniejszego badania było porównanie wpływu metforminy i insuliny
na występowanie hiperglikemii u pacjentów leczonych na oddziale intensywnej opieki medycznej (OIOM).
Materiał i metody: Badanie z randomizacją przeprowadzone metodą podwójnie ślepej próby obejmowało 24 chorych przyjętych na
OIOM w okresie od 20 marca do 20 października 2007 roku. Wszystkich pacjentów z ciężkimi obrażeniami lub po poważnych zabiegach
chirurgicznych niedotyczących jamy brzusznej, którzy spełniali kryteria włączenia, przydzielono losowo do jednej z grup terapeutycznych.
U chorych przydzielonych do grupy 1. stosowano intensywną insulinoterapię, natomiast chorym z grupy 2. podawano metforminę.
Do oceny ciężkości stanu chorych wykorzystano skalę APACHE (Acute Physiologic Assessment and Chronic Health Evaluation) II.
Wyniki: Oba protokoły leczenia hipoglikemizującego spowodowały istotną poprawę wyrównania glikemii, przy czym nie odnotowano
żadnego przypadku hipoglikemii. W grupie stosującej insulinoterapię średnie stężenie glukozy obniżyło się istotnie w stosunku
do wartości wyjściowych po dożylnym wlewie insuliny (p < 0, 001). U osób leczonych metforminą po 2 tygodniach przyjmowania
leku stężenie glukozy we krwi było istotnie niższe od poziomu wyjściowego (p < 0,001). Redukcja stężenia glukozy w ciągu tych
2 tygodni była istotnie większa w grupie przyjmującej insulinę (p = 0,01). W obu grupach terapeutycznych punktacja w skali APACHE II
w momencie zakończenia badania była niższa od wartości wyjściowych (10 punktów v. 15 [insulina] i 16 [metformina]). U 3 chorych
(2 osoby przydzielone do leczenia metforminą i 1 osoba przydzielona do insulinoterapii) zaobserwowano rozwój niewydolności
nerek de novo (maksymalne stężenie kreatyniny w surowicy co najmniej 2-krotnie większe od wartości wyjściowych) w ostatnich
dniach stosowania protokołu leczenia hipoglikemizującego, chociaż u żadnego z pacjentów nie stwierdzono kwasicy mleczanowej
po przyjęciu na OIOM.
Wnioski: Zarówno leczenie metforminą, jak i intensywna insulinoterapia istotne zmniejszają hiperglikemię u pacjentów na OIOM. Insulina
powoduje większą redukcję stężenia glukozy, jednak jej stosowanie wymaga większej uwagi, a personel medyczny musi być odpowiednio

The Efficacy of Intraoperative Ketamine-Haloperidol for Prevention of Catheter-related Bladder Discomfort After Lumbar Spinal Stenosis Surgery
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 significantly 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
Sanyar Video Laryngoscope Improved Time and First Pass Success of Tracheal Intubation in Intensive Care Unit in Compared to Direct Laryngoscopy
Background: Airway management and tracheal intubation in the ICU is a difficult procedure that may be concomitant with major complications. The purpose of this study was to evaluate the effect of the SANYAR ® video laryngoscope(S-VL) on laryngeal view and first Pass Success of tracheal Intubation compared with direct laryngoscopy.
Methods: This comparative, prospective clinical study was conducted on 120 adult patients in a single-center, in a surgical ICU under the supervision of an anesthesiologist in a university hospital. Difficult airway predictors, glottic view, first Pass Success of tracheal Intubation and time of intubation were evaluated with Macintosh laryngoscopy (ML) or the SANYAR® Video Laryngoscope(S-VL).
Results: Tracheal intubation was performed in 58 critically ill patients using ML and 62 patients using S-VL. According to Cormack and Lehane (C&L) grading glottic visualization was more difficult using ML (41%, C&L grade 3 and 4) compared with S-VL (13%, C&L grade 3 and 4) p<0.001. Intubation of trachea was more successful in the first attempt, in patients with at least one difficult airway predictor with a S-VL compared to ML (87% vs. 38%; P = 0.001), time of intubation was also shorter by using S-VL.
Conclusion: Among critically ill patients in the intensive care unit, who require intubation, the SANYAR video laryngoscopy improved glottis view compared to the Macintosh direct laryngoscopy and first-pass orotracheal intubation rate especially in patients with potentially difficult airways
The role of glutathione-S-transferase polymorphisms on clinical outcome of ALI/ARDS patient treated with N-acetylcysteine
SummaryOxidative stress has a proven role in pathophysiology of acute respiratory distress syndrome. The antioxidant drugs, especially N-acetylcysteine (NAC) have been used for years to overcome oxidative stress effects in patients. In the present study we have investigated the effects of NAC treatment (IV NAC in 150mg/kg at the first day followed by 50mg/kg/day for three days) on 27 ICU patients with ALI/ARDS considering the glutathione-S-transferase genetic variations, as an important enzyme contributing in oxidative stress pathways. The results indicated that NAC improved oxygenation (increase in PaO2/FiO2) and decreased mortality rate in treated patients compared to control group (p<0.05). Evaluation of three isoforms of glutathione-S-transferase (GST M1, P1 and T1), in these patients have showed an association between GST M1 null, and GST M1 and T1 double null polymorphisms with increased mortality in control group, suggesting antioxidant therapy critical for this group of patients
Gestational diabetes mellitus: Major risk factors and pregnancy-related outcomes: A cohort study
Background: Gestational diabetes mellitus (GDM) is a major pregnancy endocrine problem that has several confirmed risk factors and is associated with adverse pregnancy-related outcomes (PRO).
Objective: To evaluate the relationship between GDM diagnosis and the associated risk factors of PRO (maternal, intrapartum, perinatal, and neonatal) in accordance with International Association of Diabetes and Pregnancy Study Groups criteria.
Materials and Methods: This prospective cohort study was performed with 531 singleton parturient (265 GDM and 266 non-GDM). They were selected consecutively from referral hospitals, and the maternal, intrapartum, perinatal, and neonatal outcomes were assessed.
Results: The major risk factors influencing the GDM diagnosis were maternal age, obesity, family history of diabetes, previous history of GDM, and previous history of macrosomia. In the comparison of PRO between the groups, significant associations were detected for emergency cesarean delivery, preeclampsia, polyhydramnios, premature rupture of membrane, preterm delivery, and neonatal hyperbilirubinemia in the GDM group. In the multivariate logistic regression analysis, a previous history of stillbirth was significantly associated with maternal and perinatal outcomes. The odds ratios (CI 95%) of the PRO in the women with a GDM diagnosis were: maternal = 2.43 (1.51-3.90), intrapartum = 2.05 (1.35- 3.11), perinatal = 2.00 (1.29-3.10), and neonatal = 1.68 (1.08-2.62). The PRO was significantly correlated with GDM diagnosis, but not with the risk factors.
Conclusion: The adverse pregnancy outcomes were significantly correlated with GDM diagnosis, and the outcomes were not directly affected by the risk factors. Given the related adverse outcomes for mothers and offspring, early screening and management of GDM is necessary especially in Asians and in low-/middle-income countries.

Evaluation of the Role of Hemoperfusion on Mortality and Morbidity in Patients with Severe Coronavirus Disease 2019 (COVID- 19)
Background: Cytokine storm in severe Covid-19 disease is one of the leading causes of death in these patients. Hemoperfusion is a method used to purify the blood from toxins and inflammatory factors. The aim of this study was to evaluate the effect of hemoperfusion on mortality and morbidity in patients with severe Covid - 19 disease.
Methods: This was a retrospective study which performed by reviewing the files of 30 patients with severe Covid-19 disease referred to Sina Hospital affiliated to Tehran University of Medical Sciences in 2020. Thirty patients with severe covid-19 disease and positive PCR participated in the study. All patients received routine treatment protocol for covid-19. Hemoperfusion was used for 15 patients in addition to receiving routine care. The remaining 15 patients were included in the control group. Patients in the hemoperfusion group underwent four sessions of hemoperfusion using continuous renal replacement therapy with continuous venovenous hemofiltration.
Results: the ICU length of stay in the control and hemoperfusion groups was 3.40 ± 11.40 and 9.65 ± 16.33 days, respectively (P= 0.075). 8 patients died and 7 patients were discharged in the control group, but 11 patients died and 4 patients were discharged in the hemoperfusion group (P= 0.256). The respiratory rate of patients in the control and hemoperfusion groups decreased from 7.43 ± 29.40 to 4.03 ± 24.60 and from 6.11 ± 31.60 to 5.04 ± 24.46, respectively (P < 0.001). The percentage of arterial blood oxygen saturation in the control and hemoperfusion groups increased from 90.86 ± 5.61 to 93.06 30 4.30 and from 92.33 26 3.26 to 92.06 31 5.31, respectively (P= 0.456).
Conclusion: Hemoperfusion could not prevent the mortality of patients and finally out of 15 patients, 11 patients died and 4 patients were discharged. Also, no significant difference was observed between the two groups in terms of arterial blood oxygen saturation
