BACKGROUND: Endoscopy provides valuable diagnostic information and intervention therapies for gastroenterologists. Therefore, various drugs have been used to induce sedation in patients undergoing endoscopy, whereas none have been considered preferred by endoscopists. In the current study, we decided to use the combination of magnesium sulfate, ketamine, and their synergistic effects for creating partial analgesia to increase the satisfaction of endoscopists and patients. METHODS: This study is a Double-Blind Randomized Clinical Trial that investigates the sedative effect of ketamine, magnesium sulfate, and propofol in endoscopy. Patients were selected from individuals over 12 years old and with American Society of Anesthesia (ASA) physical status I or II. The study was performed on 210 patients classified as ASA (I have no underlying disease) or II (with underlying controlled disease). The whole group was relieved of pain through sedation according to Ramsay criteria, satisfaction with the operation, duration, recovery, nausea and vomiting, hypotension, and decreased oxygen saturation were compared. RESULTS: A total of 155 patients were enrolled in our study, including 51 patients (midazolam and propofol), 55 patients (midazolam and ketamine), and 49 patients (midazolam and ketamine and magnesium). The results showed that preoperative heart rate, intraoperative systolic blood pressure, intraoperative diastolic blood pressure, postoperative heart rate, postoperative systolic blood pressure, and postoperative heart rate were significantly different between the groups. CONCLUSION: The satisfaction of the endoscopic was achieved to a great extent, mainly in the group receiving midazolam and propofol and in the group receiving midazolam and ketamine. In most cases, the satisfaction of the endoscopic was acceptable, and the low satisfaction of the endoscopic was more in the group receiving midazolam. Ketamine and magnesium were observed. The two compounds midazolam-ketamine, and midazolam-propofol, have a more favorable effect than the combination of midazolam, ketamine, and magnesium.
RESUMO
BACKGROUND: In this double-blinded randomized clinical trial, we aimed to compare the safety and efficacy of a combination of Dexmedetomidine and Ketamine (DK) with Propofol and Fentanyl (PF) for sedation in colonoscopy patients. METHODS: In this study, 64 patients who underwent colonoscopy were randomized into two groups: 1) A, which received PF, and 2) B, which received DK for sedation. Among 64 patients, 31 patients were included in PF, and 33 patients were included in the DK group. Both groups were similar in terms of demographics. Patients' sedation score (based on Ramsay sedation scale) and vital signs were recorded at 2, 5, 10, and 15 minutes. Complications including apnea, hypotension, hypoxia, nausea, and vomiting, along with gastroenterologist satisfaction and patients' pain score (based on Wong-Baker faces pain assessment scale), were recorded by a checklist. Data were analyzed by SPSS v.18 software, using chi-square, independent t-tests, and repeated measures analysis with p<0.05 as the criterion for significant differences. RESULTS: The mean score of sedation was 4.82±0.49 in the DK group and 5.22±0.45 in the PF group (p value=0.001). Serious complications, including hypotension (p value=0.005) and apnea (p value=0.10) were significantly higher in the PF group. Satisfaction of gastroenterologist (p value= 0.400) and patients' pain score (p value = 0.900) were similar among groups. CONCLUSION: Combination of DK provides sufficient sedation with fewer complications in comparison with PF in colonoscopy patients.

BACKGROUND: After the spread of novel coronavirus disease 2019 (COVID-19) from Wuhan to Iran, gastroenterology clinics, was faced with a large number of patients who were suspected of being infected with the SARS-CoV-2. Among refereed patient, the incidence of pure hyperbilirubinemia as rare gastrointestinal (GI) symptoms was obvious. METHODS: In this case series, we have reported the clinical data in details for patients with COVID-19 who have been admitted to the Shahid Beheshti Hospital in Qom city, from 3 March to 3 August 2020. COVID infection, be confirmed by using real-time reverse-transcriptase polymerase chain reaction (rRT-PCR) and chest computed tomography (CT) scan, as well. RESULTS: According to the clinical findings, pure hyperbilirubinemia may consider as rare gastrointestinal (GI) symptom of COVID-19. However, it is possible that the other GI enzymes values fall in to the normal range. CONCLUSION: In some infected patients, GI physicians may face hepatic involvement as pure hyperbilirubinemia. At the age of COVID-19 crisis, all GI physicians should be aware of the possible occurrence of hepatic involvement as an important prognosis of COVID pneumonia and it should be exactly addressed in new referred patients to GI clinic.

BACKGROUND: Following surgery, patients frequently suffer from shivering, and this can lead to postoperative complications and discomfort. OBJECTIVES: This study aimed to compare the effect of ketamine on patients' shivering following an elective abdominal hysterectomy. Patients were given either Ketamine (0.25 mg or 0.5 mg/kg) or a placebo. The study and surgery took place in a subspecialty University Hospital for Gynecology and Obstetrics. METHODS: This study was an interventional, randomized, controlled clinical trial. Ninety-six women who underwent elective abdominal hysterectomy were randomly assigned to three groups. Ketamine was administered to all participants 20 min prior to the end of surgery. The first group received 0.25 mg/kg of intravenous ketamine. The second group received 0.5 mg/kg intravenous ketamine. The third group received a placebo of intravenous saline. Postoperative shivering, sedation grade, hallucination, nausea, vomiting, and nystagmus were measured for each patient up to 30 minutes. RESULTS: The study showed that patients suffered from less shivering in the two groups that received ketamine. The reduced shivering was seen 5, 10, and 20 min following surgery in the two groups that were given two doses of 0.25 and 0.5 mg/kg ketamine compared to the control group (P value < 0.05). There was a significant difference between patients receiving normal saline and those having 0.25 and 0.5 mg/kg of ketamine in the rate of sedation grade, nausea, vomiting, and nystagmus (P value < 0.05). The main differences in patients receiving ketamine were the sedation grade at zero time and postoperative hallucination experienced by those patients who received 0.5 mg/kg of ketamine. CONCLUSIONS: Ketamine reduced shivering in all patients following elective abdominal hysterectomy. This was regardless of dose. Patients were less likely to suffer from hallucinations and sedation grade with a lower dose of ketamine (0.25 mg/kg compared to 0.50 mg/kg).
RESUMO
The 2019 novel coronavirus (officially known as severe acute respiratory syndrome coronavirus 2, SARS-CoV2) was first found in Wuhan, China. On February 11, 2020, the World Health Organization (WHO) has declared the outbreak of the disease caused by SARS-CoV2, named coronavirus disease 2019 (COVID-19), as an emergency of international concern. Based on the current epidemiological surveys, some COVID-19 patients with severe infection gradually develop impairment of the respiratory system, acute kidney injury (AKI), multiple organ failure, and ultimately, death. Currently, there is no established pharmacotherapy available for COVID-19. As seen in influenza, immune damage mediated by excessive production of inflammatory mediators contributes to high incidence of complications and poor prognosis. Thus, removal or blocking the overproduction of these mediators potentially aids in reducing the deleterious cytokine storm and improving critically ill patients' outcomes. Based on previous experience of blood purification to treat cytokine storm syndrome (CSS) in severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), here we aimed to review the current literature on extracorporeal hemoperfusion as a potential therapeutic option for CSS-associated conditions, with a focus on severe COVID-19.
RESUMO
BACKGROUND: The coronavirus disease 2019 (COVID-19) has become a pandemic health problem worldwide. In this study, we attempted to explain the clinical and laboratories characteristics of non-surviving patients, to identify the probable factors affecting disease progression. METHODS: In a retrospective study, we assessed the data from dead adult patients who were hospitalized and laboratory diagnosed with COVID-19 during March 2020. The data were obtained from electronic medical records. Moreover, a checklist including demographic, clinical, laboratorial, imaging, and treatment data was completed for each one of the patients. In case of lack of information, a member of the research team contacted the first-degree relatives via phone. RESULTS: Totally, 50 patients were enrolled in this study. The mean age was 68.0 ± 14.1 years. Of them, 29 (58%) patients were male. Notably, the median (IQR) hospitalization time was 4.0 (2.7-6.2) days and the duration between the first symptoms to death was 10.0 (5.0-14.5) days. Also, pre-existing morbidity was reported in 42 (84%) patients, and hypertension was the most common one with 28 (54%) patients. Interestingly, body temperature more than 37.5°C was reported in only 20 (40%) patients. Nevertheless, neutrophilia (≥7109/L) and lymphopenia (<1.0 109/L) were observed in 27 (54%) and 29 (58%) patients, respectively. Also, elevated levels of creatinine, lactate dehydrogenase (LDH), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were common, which may be indicators of aggravation of the patients' status. CONCLUSION: Besides age and underlying diseases, elevated creatinine level, neutrophil count, and the inflammatory indices along with the reduced lymphocyte count can be considered as indicators of disease progression. Hence, they should be considered for admission and surveillance of patients.

BACKGROUND Gastrointestinal endoscopic procedures are widely used for diagnostic and therapeutic measures. Analgesia and sedation/anesthesia are inseparable parts of these studies and their related complications are inevitable. METHODS In a retrograde descriptive study in Shahid Beheshti Hospital, affiliated to Qom University of Medical Sciences, Qom, Iran from March 2013 to March 2017, we gathered information regarding common anesthesia related complications and analyzed them. RESULTS 44659 procedures were performed during the study period and records of 21342 men (47.79%) and 23317 women (52.21%) were evaluated. Hemodynamic instability (9998; 22.39%), dysrhythmia (1600; 3.58%), desaturation (608; 1.36%), prolonged apnea (34; 0.08%), aspiration (43; 0.10%), postoperative nausea and vomiting (PONV) (636; 1.42%), headache (106; 0.24%), delirium (51; 0.11%), aphasia (1; 0.00%), masseter muscle spasm (1; 0.01%), myocardial infarction (2; 0.00%), and death (5; 0.01%) were seen in the patients. CONCLUSION Sedation/anesthesia is enough safe in gastrointestinal endoscopic procedures to enhance the patients' satisfaction and cooperation. If anesthesia with spontaneous breathing and unsecure airway is selected for this purpose, vigilance of anesthesia provider will be the key element of uneventful and safe procedure.
RESUMO
BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is an endoscopic method for treatment of many biliary diseases. With respect to rapid recovery and more patient comfort, this procedure is currently performed under light general anesthesia (GA) or conscious sedation. OBJECTIVES: The current study aimed to clarify that intravenous sedation or light general anesthesia can be performed without great fear of anesthesia related complications in ERCP patients and sedative doses of propofol can be used safely in outpatient settings under the supervision of an expert anesthesiologist. METHODS: This is a cross-sectional study on 1023 ERCP patients under light GA during 2014 - 2018 in Qom, Shahid Beheshti Hospital. Data were collected by a checklist and were analyzed by using chi-square test in SPSS V.22. RESULTS: From 1023 patients, 501 (48.97 %) were male and 522 (51.03 %) were female with a mean age of 47.2 ± 6.7 years. The most common finding in ERCP was choledocholithiasis (76.15 %). The most common complication was hemodynamic instability (37.01 %) followed by desaturation (11.65 %) both of them ware anesthesia related. Prevalence of GI (gastrointestinal) related complications was 13.39 %. The most common GI related complications were pancreatitis (7.92 %) and bleeding (3.32 %). Total mortality rate was 0.88 %. CONCLUSIONS: ERCP-related complications are inevitable but can be controlled by early diagnosis and clinical experience. Severe complications and high risk patients may increase the mortality and morbidity of the procedure. Anesthesia related complications are more frequent than GI related unwanted events. Fortunately, the most common anesthesia related complications are readily manageable and are minor in nature when an expert anesthesiologist is present in the scene. Close monitoring of the patient's vital signs should be the mainstay of the safe procedure.
RESUMO
Masseter muscle rigidity is a known complication of drugs such as succinylcholine and volatile agents. However, muscle rigidity is an uncommon complication of propofol. We report the case of a 56-year-old ASA-PS class I woman refereeing for colonoscopy due to chronic constipation under deep intravenous sedation. She suffered masseter spasm after the injection of propofol. Masseter spasm should not be considered limited to special drug groups. In any case of difficult mouth opening, masseter spasm should be kept in mind and deepening of anesthesia or complete blockade of neuromuscular junction should be considered by the use of non-depolarizing muscle relaxants.
RESUMO
Central venous catheterization is a common procedure in critical care and trauma patients. Complications are not rare and in some studies more than 15% incidence has been reported (1). Femoral vein is one of the commonest site for this purpose yet it carries complications, such as infection and misplacement. The current study reports an unexpected secondary malposition of right femoral CVC in the peritoneal cavity. It was concluded that in any case of acute abdominal issues, following insertion of femoral venous catheter, evaluation of catheter misplacement by the means of contrast injection through it can be helpful for better diagnosis, and may help avoid unnecessary surgical interventions.
RESUMO
BACKGROUND: Preemptive analgesia is the blocking of pain perception afferent pathways before noxious painful stimuli. Clonidine is an alpha agonist drug that is partially selective for α-2 adrenoreceptors. Clonidine is used as anti-anxiety medication and an, analgesic, and it prolongs the duration of the block in the brachial plexus block. OBJECTIVES: To compare the effect of preemptive clonidine with midazolam on intraoperative sedation, duration of block, and postoperative pain scores. PATIENTS AND METHODS: In a randomized clinical trial, 80 patients with orthopedic fractures of an upper extremity who underwent supraclavicular nerve block were randomly assigned to receive 0.2 mg oral clonidine or 2 mg oral midazolam. Intraoperative sedation was measured at one hour after the start of urgery and again in the PACU (Post-Anesthesia Care Unit) using the Ramsay scale. The duration of sensory blockade was measured. Postoperative pain scores were measured using the VAS (Visual Analogue Scale) after entrance to recovery up to 2 hours. RESULTS: The percentages of patients in the calm and sedated scale were significantly higher in clonidine group (35 and 42.5%, respectively), compared to the midazolam group (17.5 and 17.5%, respectively) (P = 0.042, 0.029; respectively). Those administered fentanyl in the clonidine group 105 ± 30.8 was significantly lower than that for the midazolam group 165 ± 34.5 (P = 0.0018). The percentages of patients in the calm scale were significantly higher in the clonidine group (52.5), compared to the midazolam group (17.5) (P = 0.001) in the post-operative period. VAS scores were significantly lower at one (P = 0.01) and two hours (P = 0.001) after operation in the clonidine group, compared to the midazolam group. CONCLUSIONS: Preemptive clonidine has many marvelous advantages over midazolam, including better sedation inside the operating room and then in the post-operative care unit, lower fentanyl doses are required during surgery, more stable heart rate and blood pressure are observed during the procedure, and patients report lower post-operative pain scores.
RESUMO
BACKGROUND: Addicted patients have innate tolerance to local anesthetics in both neuraxial and peripheral blocks. Dexmedetomidine (Dex) is a highly selective α2 adrenergic receptor agonist used as additive to increase quality and duration of peripheral nerve blocks. OBJECTIVES: The current study aimed to compare the effect of dexmedetomidine and fentanyl additives on bupivacaine to prolong the duration of block and minimizing side effects. PATIENTS AND METHODS: Patients were candidates for elective surgery less than three hours of lower abdomen or lower extremities surgeries. Patients were randomly allocated to receive dexmedetomidine 5 µg added to 12.5 mg (2.5 mL) of 0.5% hyperbaric bupivacaine (DEX group), or 25 µg (0.5 mL) fentanyl added to 12.5 mg (2.5 mL) of 0.5% hyperbaric bupivacaine (F group) or only 12.5 mg of 0.5% hyperbaric bupivacaine. Data were recorded based on sensory block. Motor block was tested using modified Bromage scale every 30 minutes until the end of block. Time to return of sensory block to 4 dermatomes below and time to return of Bromage scale to 0 were recorded. All vital measurements (oxygen saturation, heart rate, electrocardiogram, and non-invasive blood pressure) were performed at 0, 30, 60, 90, 120 and 180 minutes in all three groups of the study. Group DEX received dexmedetomidine additive and group F received fentanyl additive and group C (control) received normal saline. RESULTS: Totally, 84 patients were randomly divided into three groups of 28 patients. Onset of sensory block in DEX group was significantly lower than those of fentanyl (P = 0.012) and control groups (P = 0.001). Duration of sensory block was significantly longer in DEX group compared to Fentanyl (P = 0.043) and control (P = 0.016) groups. Duration of motor block in the DEX group was significantly longer than those of the fentanyl (P = 0.014) and control groups. Heart rate and mean arterial pressure were significantly higher in the DEX group at 30, 60, 90,120, and 180 minutes compared to those of the other two groups (P < 0.05). CONCLUSIONS: Dexmedetomidine added to bupivacaine in spinal anesthesia is more effective to increase duration of block, providing more appropriate sedation and less postoperative pain scale and post-operative nausea and vomiting (PONV) compared to fentanyl additive.
