Evaluation of gastroesophageal reflux in pediatric laparoscopic appendectomy procedures.

BACKGROUND: The increased intra-abdominal pressure during laparoscopic surgical procedures was reported to be a factor in the development of gastroesophageal reflux. This study evaluated the presence of gastroesophageal reflux and associated factors using 24-h pH monitoring in children undergoing laparoscopic appendectomy. METHODS: Children who underwent laparoscopic surgery for presumed acute appendicitis between June 2017 and June 2018 were included in the study. After pre-operative endotracheal intubation, pH catheters were placed for 24-h esophageal pH monitoring. Relationships between gastroesophageal reflux and procedure time, pre-operative fasting time, age, weight, and body mass index (BMI) were evaluated. RESULTS: A total of 60 pediatric patients were included in the study. Their mean (SD) age was 11.82 (3.71) years (range, 4-17 years). The mean (SD) body weight was 41.27 (16.72) kg (range, 15-90 kg) and the mean (SD) BMI were 17.96 (4.37). The mean pre-operative fasting time was 15.52 (12.1) h, while the mean operative time was 38.42 (17.96) min. Lower age and weight were significantly associated with the presence of post-operative gastroesophageal reflux (p<0.05). Mean procedure time, mean pre-operative fasting time, and BMI were not significantly associated with intra- or post-operative gastroesophageal reflux (p>0.05). CONCLUSION: The lack of a significant relationship between mean procedure time and gastroesophageal reflux suggests that the mean duration of the laparoscopic procedures performed in this study is safe in terms of gastroesophageal reflux. The results also indicate that young age and low weight should be considered risk factors for gastroesophageal reflux in pediatric patients undergoing laparoscopic appendectomy.

Evaluation of Anxiety, Depression, and Work-Related Strain Inventory of Code Blue Teams in Turkey During the COVID-19 Pandemic: A Cross-Sectional Survey Study.

OBJECTIVE: This study aimed to evaluate the anxiety, depression, and work-related strain inventory with a cross-sectional electronic questionnaire in code blue teams during the coronavirus disease-2019 pandemic in Turkey. METHODS: A web-based electronic questionnaire was sent to healthcare workers registered in the database of the Turkish Society of Anaesthesiology and Reanimation and the Turkish Resuscitation Council who are in the code blue teams of the hospital where they work. An electronic questionnaire including the hospital anxiety-depression scale and the work-related strain inventory was sent to healthcare professionals. A total of 259 participants who answered the questionnaire were included in the study. RESULTS: It was determined that 41.3% (n=107) of all participants were at risk in terms of anxiety and 64.1% (n=166) were at risk in terms of depression by taking above the threshold value. The mean work-related strain inventory score of the participants was found to be 41.19 ± 6.31. The mean work-related strain inventory values of the participants who received above-threshold values from both the anxiety and depression subscales were also found to be statistically significantly higher than the participants who received below-threshold values (P <.001). CONCLUSION: It was determined that approximately half of the code blue teams were at risk for anxiety and two-thirds of them for depression.

Association between acute kidney injury and mortality after successful cardiopulmonary resuscitation: a retrospective observational study.

BACKGROUND AND OBJECTIVES: Acute Kidney Injury (AKI) affect mortality and morbidity in critically ill patients. There have been few studies examining the prevalence of AKI and mortality after successful cardiopulmonary resuscitation. In the present study, we investigated the association between AKI and mortality in post-cardiac arrest patients admitted to the Intensive Care Unit (ICU). METHODS: Our retrospective analysis included 109 patients, admitted to the ICU following successful cardiopulmonary resuscitation between 2014 and 2016. We compared two scoring systems to estimate mortality. RESULTS AND DISCUSSION: AKI were diagnosed in 46.7% (n = 51) of the patients based on the RIFLE criteria and 66.1% (n = 72) using the KDIGO. Mortality rate was significantly higher among patients with AKI diagnosed according to the RIFLE criteria (p = 0.012) and those with AKI diagnosed using KDIGO criteria (p = 0.003). Receiver Operating Characteristic (ROC) analysis showed that both scoring systems were able to successfully detect mortality (Area under the ROC curve = 0.693 for RIFLE and 0.731 for KDIGO). CONCLUSION: AKI increases mortality and morbidity rates after cardiac arrest. Although more renal injury and mortality were detected with KDIGO, the sensitivity and specificity of both scoring systems were similar in predicting mortality in patients with Return of Spontaneous Circulation (ROSC).

Evaluation of Cardiopulmonary Resuscitation Conditions in Turkey: Current Status of Code Blue.

OBJECTIVE: Globally, previously determined teams activated by 'code blue' calls target rapid and organised responses to medical emergency situations. This study aimed to evaluate the cardiopulmonary resuscitation (CPR) conditions in Turkey. METHODS: A web-based survey was sent to anaesthesiologists in Turkey via email. The survey included 36 questions about demographic features and 'code blue' practices and procedures. RESULTS: A total of 180 participants were included. The mean working duration was 16.1±7.5 years. Of the anaesthesiologists who participated, 35% worked in university, 26.1% in education and research, 1.7% in city hospitals, 18.9% in state hospitals and 18.3% in private hospitals; 68.3% had CPR certification. There were code blue systems in 97.6% of the organisations. For code blue calls, 71.9% were activated by calling '2222'. There were 41.5% organisations with code blue teams of 3-4 people, whereas 26.7% had 2-member teams. Among call responders, 68.5% were anaesthesia technicians/paramedics, 60.7% were anaesthesiologists and 42.7% were anaesthesia assistants. In organisations, 66.3% regularly conducted code blue training. In total, 63.3% of the participants stated that the time to reach the location was nearly 2-4 minutes. During CPR, the use of capnography was 18.3%. Of the participants, 73.8% chose endotracheal intubation as priority airway device during CPR. CONCLUSION: Today, code blue practice is an important quality criterion for hospitals. This study shows the current status of 'code blue' according to the results of respondent data completing the survey. To prevent in-hospital cardiac arrest, a chain of preventive measures should be established, including personnel training, monitoring of patients, recognition of patient deterioration, the presence of a call for help system and effective intervention.

Evaluation of Nurses' Approaches to Deteriorating Patients: Survey Study.

OBJECTIVE: Prevention of cardiopulmonary arrest in hospitalised patients is the first and most important step in the life-saving chain. When the condition of the inpatients is worsened, nurses are usually the first to see and evaluate the patient. The aim of this study was to evaluate the attitudes of the nurses working at the Mersin University Hospital, during their routine follow-up to the deteriorating patients and the early warning scoring (EWS) awareness. METHODS: A web-based questionnaire was sent to all nurses working in inpatient services and intensive care units (ICUs) and registered to the hospital database at Mersin University Hospital via e-mail. In the questionnaire, a total of 10 multiple-choice questions were asked to the nurses questioning the unit they worked for, the EWS they used, the complaints they frequently complain about and the applications for the call for help. A total of 146 nurses were included in the study. RESULTS: 43.8% (n » 64) of the participants were in ICU, and 56.1% (n » 82) were in service units. Participants were asked whether they used a special scoring system to recognise the deteriorating patient; 45.2% (n » 66) used the scoring system; and 54.8% (n » 80) reported that they did not use it. Participants working in ICU were more likely to use EWS system. Participants answered the most commonly used scoring system as the Glasgow Coma Scale (n » 40). The participants reported that the most common respiratory distress (n » 135), changes in consciousness (n » 109), palpitations (n » 98) and chest pain (n » 92) occurred in the deteriorating patients. Participants reported that they frequently asked for help from a doctor (80.1%), other nurses (7.5%) and a blue code team (7.5%). CONCLUSION: According to the findings, it is necessary to determine the habits of calling for help and raising awareness for a functional EWS.

Evaluation of Gastroesophageal Reflux in Children as a Risk for Post-operative Nausea and Vomiting: An Observational Study.

1Background: Anaesthesia is known to reduce gastric emptying and motility, which can cause gastroesophageal reflux (GER) in some patients. Monitoring pH is a reliable method for detecting reflux. In this study, we aimed to show whether GER is a risk factor for post-operative nausea and vomiting (PONV) with oesophageal reflux measures in paediatric patients undergoing laparoscopic appendectomy. METHODS: After obtaining approval from ethics committee, 55 paediatric patients were included. An oesophageal pH metre catheter was inserted through the nasal passage to 3 cm above the lower oesophageal sphincter. pH measurements were evaluated with DeMeester score. It was accepted as acid reflux if the score was >14.7. The patients' demographic data, history of GER and verbal descriptive scale (VDS) to assess PONV and pH values were analysed with Statistical Package for the Social Sciences (SPSS) version 21 (IBM SPSS Corp.; Armonk, NY, USA). RESULTS: Of the 55 patients, 41.8% were girls, 58.2% were boys, the mean age was 13.2 years, the mean fasting period was 7.47 hours and the mean operation time was 1.1 hours. Mean fasting and operation times did not differ statistically according to VDS. There was no significant association between VDS group and gender or pH. None of the patients had a history of GER. Thirteen patients had DeMeester score >14.7. CONCLUSION: This is the first study about the relationship between gastric pH and PONV in paediatric patients. Although some studies have shown an association between anaesthesia and reflux, we detected reflux in nine of our patients and reflux was not statistically associated with PONV in our study. Further studies with larger patient groups are needed to provide a clearer opinion.

Evaluation of miRNAs Related with Nuclear Factor Kappa B Pathway in Lipopolysaccharide Induced Acute Respiratory Distress Syndrome.

This study aimed to determine the expression of nuclear factor kappa B (NF-κB) pathway related miRNAs in experimental acute respiratory distress syndrome (ARDS) induced by lipopolysaccharide (LPS) in rats, and to elucidate the underlying molecular mechanism. Twenty four sprague dawley rats were randomly divided into two groups; LPS (n = 12) and control (n = 12). Experimental ARDS was induced by intraperitoneal injection of E. coli LPS in LPS group. Intraperitoneal saline was administered in control group. Serum and lung samples were collected from both groups. Immunohistochemistry staining was performed for interleukin 1ß (IL-1ß), tumor necrosis factor α (TNF-α), CD 68, and caspase-3 in lung samples. Intensity of staining was scored as strong, moderate, weak, and no for evaluation of IL-1ß and TNF-α. In addition, caspase-3 and CD68-positive stained cells were counted in sections. Expressions of 9 miRNAs were determined by quantitative real-time PCR in serum samples. IL-1ß and TNF-α staining scores were significantly higher in the LPS group in comparison with the control group (P = 0.04 and P = 0.02, respectively). In addition, caspase-3 and CD68-positive stained cells were significantly higher in the LPS group (P = 0.02). Expressions of seven miRNAs were significantly changed in the LPS group in comparison with the control group. While six miRNAs (miR-7a-5p, miR-7b, miR-9a-5p, miR-21-5p, miR-29a-3p, and miR-138-5p) were up regulated, only miR-124-3p was down regulated. This study suggests that these miRNAs may have a role in the pathogenesis of ARDS related to NF-κB. However, this relationship needs to be examined in new studies by evaluation of pathways and target genes.

Community acquired infections among refugees leading to Intensive Care Unit admissions in Turkey.

OBJECTIVES: Data on the impact of refugees on Intensive Care Units (ICUs) are lacking in the literature, in particular for community-acquired (CA) infectious diseases, for which they are known to be at higher risk. We did a descriptive, multicenter study to analyze CA infections among refugee patients requiring ICU admission. METHODS: Inclusion criteria were adult refugee patients admitted to an ICU due to CA infections. Anonymized data were collected between January 1, 2010 and December 30, 2015 across 10 referral centers. RESULTS: 29.885 patients were admitted to the ICUs in the study period. 37 patients were included the study, the majority were from Syria (n=31, 83.8%). Mean (SD) age of the patients was 45.92±20.16years. The 5-year prevalence rate was 123.8 per 100.000 patients in the ICUs. All patients had at least one comorbid condition. Forty-nine CA infections were diagnosed. The most common CA infection was pneumonia (49%) followed by urinary-tract infections (16.3%). 21 patients (56.7%) hospitalized in the ICU had trauma history. Mortality rate was high at 22 patients (59.5%) with 5 (22.7%) deaths directly attributed to CA infections. CONCLUSIONS: Refugees presented to ICUs with CA infections similar to the host populations (pneumonia and urinary-tract infections) but had high mortality rates (59.5%). It seems that Turkish ICUs were not congested with the refugee patients' influx for CA infections. More research needs to be done to better understand how to deliver preventative and timely health care services to this group of patients.

Reversal of profound neuromuscular blockade with sugammadex in an infant after bronchial foreign body removal.

Sugammadex is a selective chemical agent that can reverse neuromuscular blockade induced by vecuronium and rocuronium. The aim of this report is to discuss the effectiveness of sugammadex in the reversal of neuromuscular blockade in children younger than 2 years. A 16-month-old boy, weighing 10 kg, was admitted to the pediatric emergency department due to choking, cyanosis, and severe respiratory distress that occurred while he was eating peanuts. In the emergency department, the patient's condition deteriorated, and he went into respiratory arrest. He was immediately intubated and taken to the operating room. A rigid bronchoscopy was performed under general anesthesia, with administration of intravenous pentothal (5 mg/kg), rocuronium (0.6 mg/kg), and fentanyl (0.5 µg/kg) in the operating room. The foreign body was removed within 6 minutes, and the profound neuromuscular blockade was reversed with a dose of 2 mg/kg sugammadex. He was extubated successfully after obtaining the spontaneous respiratory activity, and adequate breathing was restored. Clinical use of sugammadex in children younger than 2 years is not recommended because of the lack of clinical studies. In this case report, the profound neuromuscular blockade was successfully reversed with a dose of 2 mg/kg sugammadex in a 16-month-old boy. However, more prospective clinical studies are required for the safe use of this agent in children.

Comparative study between the effects of dexmedetomidine and propofol on cerebral oxygenation during sedation at pediatric cardiac catheterization.

INTRODUCTION: Nowadays, assessment of brain oxygen saturation, which is simply appliable and noninvasive method, can provide the anesthesia plans to be optimized according to the needs of the brain, which is the main target organ. Brain may be exposed to hypoxia due to supply-demand imbalance of oxygen not only in general anesthesia procedures but also in sedation practices. The aim of the study is to compare the effects of dexmedetomidine and propofol which are widely used agents for pediatric catheterization procedures on brain oxygen saturation using Fore-Sight. MATERIAL AND METHODS: A total of 44 patients undergoing diagnostic cardiac catheterization between 1 and 18 years old were included in the study. All patients, who were randomly divided into two groups, had ASA physical status I-II. In Group Propofol (Group P, n = 22),induction of sedation was made by midazolam (0.5 mg,iv) + propofol (1m/kg,iv), and in Group Dexmedetomidine (Group D, n = 22), induction of sedation was made by midazolam (0.5 mg,iv) +dexmedetomidine (1mcg/kg, iv). Throughout the sedation, cerebral tissue oxygen saturation (SctO 2 ) was recorded by Fore-Sight in addition to routine monitoring. RESULTS: There were no statistically significant differences between the groups in terms of demographic data, hemodynamic data and sedation scores. On other hand, statistically significant decreases in cerebral tissue oxygen saturation were detected especially at 5th and 10th minutes, in Group D, while cerebral oxygenation level did not decrease in Group P. Though, statistically significant difference was determined between two groups in terms of cerebral oxygen saturation, the obtained data was not interpreted as cerebral desaturation. CONCLUSION: As a conclusion, there was a statistically significant but clinically insignificant decrease in cerebral tissue oxygen saturation in dexmedetomidine group compared to propofol group. Although it does not seem to be important in hemodynamic stabilization, we assume that may cause problems for clinically unstable patients.

Patients', who applied to the anesthesia clinic, perceptions and knowledge about anesthesia in Türkiye.

BACKGROUND: Pre-operative evaluation includes determining the patient's physiological and psychological situation, taking information about pharmacological and therapeutic history, laboratory examinations, and identifying the anesthesia risks. The aim of this study is to learn the patients', who planned for elective surgery, knowledge and perception about anesthesia, to determine the causes of fears, to investigate whether age, gender, education level, and history of operation affect the outcome of the survey. METHODS: A questionnaire consisting of 21 questions was asked to fill by the patients who applied to the anesthesia clinic. In our study, totally 250 patients, aged between 16 and 75 were included. The questionnaire consists of two parts: The first part includes demographic data such as age, gender, education level, occupation; the second part includes the questions about anesthesia experience and knowledge. RESULTS: Of the 250 patients studied, 59% were females and 41% were males. Of these patients, 37.6% had secondary education. As occupation, the highest percentage was belonging to the housewives (33.6%). In the second part of the questionnaire, it was showed that having an anesthesia experience and high education status statistically significantly affect the level of information about anesthesia (P=0.001; P=0.001). CONCLUSION: In this study, it was showed that there is an important relationship between education and past anesthesia experience and having information about anesthesia and anesthetists. But, generally it was also showed that the patients not having adequate information about anesthesia and anesthetists and to provide the public more informed about anesthesia, with hospital policies and studies of increasing education level, the individual attempts of anesthetists and continuous studies for anesthesia displaying are needed.

A comparative study of the antiemetic efficacy of dexamethasone, ondansetron, and metoclopramide in patients undergoing gynecological surgery.

BACKGROUND: Postoperative nausea and vomiting (PONV) are some of the most-common and undesirable adverse effects after surgery performed under general anesthesia. We investigated the prophylactic value of dexamethasone as an alternate to ondansetron or metoclopramide to prevent PONV after gynecologic surgery. MATERIAL/METHODS: One hundred sixty ASA I-II patients scheduled for elective gynecologic surgery were enrolled. Before induction of anesthesia, patients were randomly allocated to receive intravenously dexamethasone (8 mg) in group D, ondansetron (4 mg) in group O, metoclopramide (10 mg) in group M, and saline (2 mL) in group P. Total incidence of nausea and vomiting, rescue antiemetic requirement, pain scores, and any adverse effects were recorded at 3 observational periods (0-2 hours, 2-12 hours, and 12-24 hours). RESULTS: Total rates of PON, POV, and PONV were significantly higher in group P at 0-2 hours and 2-12 hours compared with group D, O, and M (P<.05). There was no difference in PON, POV, and PONV among D, O, and M groups. None of the groups differed in PONV in the subsequent 12-24 hours. Number of patients requiring rescue antiemetic was significantly higher in group P than the other groups at 0-2 hours (10%, 10%, 15%, and 45% in group D, O, M, and P) (P<.05). CONCLUSIONS: Prophylactic IV dexamethasone 8 mg significantly reduces the incidence of PONV in gynecologic surgery. At this dosage, dexamethasone is as effective as ondansetron 4 mg and metoclopramide 10 mg, and is more-effective than placebo.

Tracheal web: presentation of a case with uncommon features.

Postintubation tracheal web is a rarely encountered complication of endotracheal intubation. Although few of them remain asymptomatic until diagnosed accidentally, most of them present with symptoms of acute airway obstruction and even death. We present here a case of postintubation tracheal web with uncommon features, including a very long delay in diagnosis despite a 99% obstruction of the tracheal lumen.

Bispectral index monitoring in confirmation of brain death in children.

Although the guidelines for the diagnosis of brain death in children are well established, the diagnosis is still under debate, and further confirmatory tests are required. Performing these confirmatory tests presents some drawbacks, such as high costs, the need for specialized personnel and technology, transportation of patients out of the intensive care unit, and the use of contrast media. Bispectral index monitoring can provide real-time, objective, continuous monitoring of the consciousness level in critically ill children. The aim of this prospective study was to define the role of bispectral index monitoring in the confirmation and diagnosis of brain death. Eight children who had fulfilled the diagnostic criteria of brain death were included in the study. The age of patients ranged from 3 months to 15 years. All patients had electrocerebral silence on their electroencephalographic recordings. After the diagnosis of brain death, at least 2-hour monitoring was performed, and all patients expressed a score of 0, indicating brain death. According to our study, the decrease in bispectral index score to 0 in patients with suspected brain death can support and confirm brain death diagnosis in children and can enable scheduling of expensive tests, such as cerebral angiography, in the appropriate time. Nevertheless, further studies are needed to determine the role of the bispectral index in the diagnosis and confirmation of brain death in children. In this article, we review clinical utility, application time, and interpretation of bispectral index monitoring in confirmation of brain death diagnosis in children.

Safe and effective sedation and analgesia for bone marrow aspiration procedures in children with alfentanil, remifentanil and combinations with midazolam.

BACKGROUND: Invasive procedures such as bone marrow aspiration in children may be painful and cause anxiety. We investigated the efficacy and safety of remifentanil (R) alfentanil (A), remifentanil-midazolam (RM), and alfentanil-midazolam (AM) combinations in providing analgesia and sedation for bone marrow aspiration. METHODS: Eighty children undergoing a diagnostic bone marrow aspiration whose ages ranged from 5-16 years (mean 9.20 +/- 3.00 years) were enrolled in this study. The patients were randomly assigned to one of 4 treatment groups. Vital signs, sedation and pain scores, somatic responses (sweating and tears) were recorded before, during bone marrow aspiration and after 5 and 15 min of the procedure. RESULTS: There were no statistical differences between sedation and the CHEOPS scores of the four groups during and after the procedures. The VAS scores were significantly higher for group A compared with groups R and RM during the procedure (P < 0.008). There were no differences between the VAS scores in group AM compared with groups R and RM (P > 0.008). There were also no statistical differences among the VAS scores of four groups after the procedure (P > 0.008). All patients had adequate sedation and analgesia. None of the patients in the study had deep sedation, hypotension, bradycardia, hypoxemia, or respiratory depression. CONCLUSIONS: Remifentanil, alfentanil, remifentanil-midazolam, and alfentanil-midazolam combinations are effective in children and can be used safely in bone marrow aspiration which is a brief but painful procedure performed in the pediatric patient group.
