Value of integrated pulmonary index monitoring for the detection of adverse respiratory events in patients undergoing sedation for gastrointestinal system endoscopy.

Objectives: To determine if the integrated pulmonary index detects changes in ventilation status early in patients undergoing gastrointestinal endoscopy under sedation, and to determine the risk factors affecting hypoxia. METHODS: The retrospective study was conducted at the endoscopy unit of a tertiary university hospital in Turkey and comprised data between October 2018 and December 2019 related to patients of either gender aged >18 years who were assessed as American Society of Anaesthesiologists grade I-III and underwent elective lower and upper gastrointestinal endoscopy. Monitoring was done with capnography in addition to standard procedures. Data was analysed using SPSS 23. RESULTS: Of the 154 patients, 94(%) were females and 60(%) were males. The overall mean age was 50.88±11.8 years (range: 20-70 years). Mean time under anaesthesia was 23.58±4.91 minutes and mean endoscopy time was 21.73±5.06 minutes. During the procedure, hypoxia was observed in 42(27.3%) patients, severe hypoxia in 23(14.9%) and apnoea in 70(45.5%). Mean time between apnoea and hypoxia was 12.59±7.99 seconds, between apnoea and serious hypoxia 21.07±17.64 seconds, between integrated pulmonary index score 1 and hypoxia 12.91±8.17 sec, between integrated pulmonary index score 1 and serious hypoxia 21.59±14.13 seconds, between integrated pulmonary index score <7 and hypoxia 19.63±8.89 seconds, between integrated pulmonary index score <7 and serious hypoxia 28.39±12.66 seconds, between end-tidal carbon dioxide and hypoxia 12.95±8.33 seconds, and between end-tidal carbon dioxide and serious hypoxia 21.29±7.55 seconds. With integrated pulmonary index score 1, sensitivity value for predicting hypoxia and severe hypoxia was 88.1% and 95.7%, respectively, and specificity was 67% and 60.3%, respectively. With integrated pulmonary index score <7, the corresponding values were 100%, 100%, 42% and 64.1%, respectively. CONCLUSIONS: Capnographic monitoring, especially the follow-up integrated pulmonary index score, was found to be valuable and reliable in terms of finding both time and accuracy of the risk factor in the diagnosis of respiratory events.

High, Low, and Minimal Flow Anaesthesia Management: Effects on Oxygen Reserve Index and Arterial Partial Oxygen Pressure.

OBJECTIVE: To determine the oxygen reserve index (ORI) as a supporting parameter to the arterial partial oxygen pressure (PaO2) in blood gases in hypoxia and hyperoxia monitoring with different fresh gas flows (FGF) in patients undergoing abdominal surgery. STUDY DESIGN: Randomised controlled trial. Place and Duration of the Study: Department of Anaesthesiology and Reanimation, Samsun Education and Research Hospital, Turkey, from January to September 2020. METHODOLOGY: The study population of ninety patients was divided into three groups. After the high-flow period, the inspired oxygen fraction (FiO2) and flow-guided ventilation (FGF) were set to be 4 L/m and 40% in Group H (high-flow), 1 L/m and 50% in Group L (low-flow), and 0.5 L/m and 68% in Group M (minimal-flow), respectively. RESULTS: There was a very high statistically positive correlation between PaO2 and ORI in H, L, and M groups. When using a cut-off value of 0.005 for ORI for the detection of PaO2 >100 mmHg, the area under the curve (AUC) was 0.97 (p<0.001) with a sensitivity of 94.4% and specificity of 95.3%. The AUC was detected to be 0.95 in receiver operating characteristic (ROC) analysis when the hyperoxia cut-off value of ORI was used to determine PaO2 >150 mmHg in the estimation of hyperoxia. CONCLUSION: ORI can be used to complement SpO2 in low-flow anaesthesia in patients undergoing abdominal surgeries, provide guidance for PaO2, give information about tissue oxygen delivery, and contribute to the individualisation of oxygen therapy, and will therefore be included in the standard monitoring in the future. KEY WORDS: Anaesthesia, Index, Inhalation, Oxygen, Pressure, Surgery.

Comparison of the effectiveness of transversus abdominis plane block with laparoscopy or ultrasonography in laparoscopic cholecystectomy operations.

OBJECTIVES: This study aims to compare the effectiveness of the Transversus Abdominis Plane (TAP) block applied to reduce postoperative pain in laparoscopic cholecystectomy surgery by ultrasonography (USG) and laparoscopy. METHODS: A total of 170 patients who underwent laparoscopic cholecystectomy were divided into three groups. Group L received TAP block by laparoscopy, Group U received TAP block by USG, and the control group (Group C) did not receive TAP block. Bilateral subcostal 15 mL 0.5% bupivacaine was used for the TAP block. We recorded patients' demographic data and hemodynamic parameters, surgery time, anesthesia time, time of first postoperative analgesic need, visual analog scale (VAS) scores, time to first flatulence and stool, degree of nausea-vomiting, and the Turkish Revised American Pain Society Patient Outcome Questionnaire (APS-POQ-R-T) scores. RESULTS: We observed no statistically significant differences between the groups in terms of age, gender, or American Society of Anesthesiologists scores, and body mass index was higher in Group U compared to the other groups (p<0.05). The VAS score was significantly higher in the control group at all times compared to the other two groups (p<0.001). VAS measurements were higher in Group U at postoperative 1st and 12th h compared to Group L (p<0.001). Surgery time and anesthesia time were significantly different between the groups (p=0.001). Group C showed high VAS scores, high pain severity by APS-POQ-R-T at the 24th postoperative hour, and low sleep quality and patient satisfaction. CONCLUSION: For laparoscopic cholecystectomy surgery, applying TAP block with the help of USG is effective in postoperative pain management. Applying TAP block with laparoscopy is easy since it does not require additional preparation or equipment during the procedure and may be preferred in the absence of a USG device.

Does prolonged prone position affect intracranial pressure? prospective observational study employing Optic nerve sheath diameter measurements.

BACKGROUND: Our aim in this observational prospective study is to determine whether the prone position has an effect on intracranial pressure, by performing ultrasound-guided ONSD (Optic Nerve Sheath Diameter) measurements in patients with acute respiratory distress syndrome (ARDS) ventilated in the prone position. METHODS: Patients hospitalized in the intensive care unit with a diagnosis of ARDS who were placed in the prone position for 24 h during their treatment were included in the study. Standardized sedation and neuromuscular blockade were applied to all patients in the prone position. Mechanical ventilation settings were standardized. Demographic data and patients' pCO2, pO2, PaO2/FiO2, SpO2, right and left ONSD data, and complications were recorded at certain times over 24 h. RESULTS: The evaluation of 24-hour prone-position data of patients with ARDS showed no significant increase in ONSD. There was no significant difference in pCO2 values either. PaO2/FiO2 and pO2 values demonstrated significant cumulative increases at all times. Post-prone SPO2 values at the 8th hour and later were significantly higher when compared to baseline (p < 0.001). CONCLUSION: As a result of this study, it appears that the prone position does not increase intracranial pressure during the first 24 h and can be safely utilized, given the administration of appropriate sedation, neuromuscular blockade, and mechanical ventilation strategy. ONSD measurements may increase the safety of monitoring in patients ventilated in the prone position.

Can Ultrasound-Guided Femoral Vein Measurements Predict Spinal Anesthesia-Induced Hypotension in Non-Obstetric Surgery? A Prospective Observational Study.

Background and objectives: To investigate whether ultrasound (US)-guided femoral vein (FV) and inferior vena cava (IVC) measurements obtained before spinal anesthesia (SA) can be utilized to predict SA-induced hypotension (SAIH) and to identify risk factors associated with SAIH in patients undergoing non-obstetric surgery under SA. Methods: This was a prospective observational study conducted between November 2021 and April 2022. The study included 95 patients over the age of 18 with an American Society of Anesthesiologists (ASA) physical status score of 1 or 2. The maximum and minimum diameters of FV and IVC were measured under US guidance before SA initiation, and the collapsibility index values of FV and IVC were calculated. Patients with and without SAIH were compared. Results: SAIH was observed in 12 patients (12.6%). Patients with and without SAIH were similar in terms of age [58 (IQR: 19-70) vs. 48 (IQR: 21-71; p = 0.081) and sex (males comprised 63.9% of the SAIH and 75.0% of the non-SAIH groups) (p = 0.533). According to univariate analysis, no significant relationship was found between SAIH and any of the FV or IVC measurements. Multiple logistic regression analysis revealed that having an ASA class of 2 was the only independent risk factor for SAIH development (p = 0.014), after adjusting for age, sex, and all other relevant parameters. Conclusions: There is not enough evidence to accept the feasibility of utilizing US-guided FV or IVC measurements to screen for SAIH development in patients undergoing non-obstetric surgery under SA. For this, multicenter studies with more participants are needed.

Assessment of Anxiety, Depression and Work-Related Strain Levels of Healthcare Professionals Working in Operating Rooms and Intensive Care Units During the COVID-19 Outbreak.

OBJECTIVE: The purpose of the study was to determine the levels of work-related strain, anxiety, and depression in health professionals working in operating rooms and intensive care units who deal with the diagnosis, treatment, and care of coronavirus disease 19 patients. METHODS: The population of the study consisted of 320 healthcare professionals working in the operating room and intensive care units. After providing detailed information about the study to the participants, a questionnaire consisting of 21 questions including sociodemographic infor- mation and working life characteristics, 14 questions from the Hospital Anxiety and Depression Scale, and 18 questions from the Work-Related Strain Inventory (WRSI) were administered under supervision. RESULTS: In total, 58.8% of the participants were working in intensive care units, and 41.2% of the participants were in the operating room. The scores obtained from Work-Related Strain Inventory were found to be statistically significantly high in those who wanted to choose a differ- ent profession, those who were on duty during the coronavirus disease 19 pandemic process, those whose spouses followed coronavirus disease 19 patients during the pandemic, those who encountered a suspicious situation and had a coronavirus disease 19 test, those who had difficulty in accessing personal protective equipment, and those who thought that their lives were in danger during the pandemic process. Participants with anxiety risk according to Hospital Anxiety and Depression Scale-Anxiety subscale and depression risk according to Hospital Anxiety and Depression Scale-Depression subscale were found to be 153 (47.8%) and 300 (93.8%), respectively. CONCLUSIONS: It was found that Work-Related Strain Inventory and anxiety-depression rates were significantly high in both the operating room and intensive care unit workers who actively provided healthcare services to patients diagnosed with coronavirus disease 19.

[Mortality prediction ability of phycians in intensive care units of Turkey (MOPAP)]. / Türkiye'de yogun bakim ünitelerinde hekimin mortaliteyi öngörebilme gücü.

INTRODUCTION: Intensive care physicians are increasingly involved in decision making about the prognosis of intensive care unit ICU patients. With this study; we aimed to evaluate the power of clinician foresight at prediction of mortality in patient at triage to intensive care and patient follow-up. MATERIALS AND METHODS: This study was conducted in ICUs located in various geographical regions of Turkey between January 1, 2017-April 30, 2017.The clinical research was planned as observational, multicenter, cross-sectional. RESULT: A total of 1169 intubated patients were followed in 37 different ICU. At the beginning of the follow-up we asked the physician who will follow the patient in the ICU to give a score for the probability of survival of the patients. Scoring included a total of 6 scores from 0 to 5, with the "0" the worst probability "5" being the best. According to this distribution, only 1 (0.9%) of 113 patients who were given 0 points survived. Three (6.1%) of 49 with the best score of 5 died. Survival rates were significantly different in each score group (r: -0.488; p<0.001). After the combined mortality estimation scores based on the clinical observations of the physicians (0 and 1 point score was combined as non-survive, 4 and 5 score was combined as survived) 320 of the 545 patients were estimated to be dead and 225 were predicted survival. Sensitivity and spesifity of scoring system to predict mortality was 91.56% (95% CI: 87.96-94.37), 76.89% (95% CI: 70.82-82.23) respectively. CONCLUSIONS: In this study, we concluded that the physicians who follow the patients in the ICU can predict the poor prognosis at the time of admission and the high mortality rate. The physician's opinion on mortality estimation should be considered in intensive care mortality scoring in addition to other laboratory and clinical parameters.

Central line-associated blood stream infections: characteristics and risk factors for mortality over a 5.5-year period.

BACKGROUND/AIM: Central line-associated bloodstream infections (CLABSIs) are associated with substantial morbidity and mortality and the infection rates vary in a wide range1397645907(high: 62.5%; low: 20%) in developing countries. We aimed to investigate the characteristics and the risk factors for mortality in patients with CLABSIs in intensive care units (ICUs) and provide the relevant data. MATERIALS AND METHODS: The electronic medical records database and file records obtained through active surveillance by an infection control committee of a hospital were screened to identify patients with CLABSIs hospitalized from January 2008 through July 2013. RESULTS: A total of 166 CLABSI episodes in 158 patients out of 17,553 on 38,562 catheter and 94,512 hospitalization days were evaluated. The infection developed in catheterized patients at a median of 14 days (range 2-88), and the highest infection rate with 13.4% (n = 20) was the femoral region among the places where the catheter was inserted. Of the patients catheterized, 54.4% survived whereas 45.6% died. In patients having Candida infection, the mortality was significantly higher. High APACHE II scores and Candida infections were found to be significant risk factors associated with mortality. CONCLUSION: APACHE II scores and bloodstream infection with Candida species were the most powerful predictors of mortality. In ICU practice, health-care givers must consider the emerging role of Candida for both invasiveness and mortality.

Central line-associated bloodstream infections in the intensive care unit: importance of the care bundle.

BACKGROUND: The importance and efficacy of a care bundle for preventing central line-associated bloodstream infections (CLABSIs) and infectious complications related to placing a central venous catheter (CVC) in patients in the intensive care unit (ICU). METHODS: A care bundle was implemented from July 2013 to June 2014 in a medical ICU and surgical ICU. Data were divided into three periods: the prior period (July 2012-June 2013), the intervention period (July 2013-June 2014; first and second periods), and the post-intervention period (July 2014-December 2014; third period). A care bundle consisting of optimal hand hygiene, skin antisepsis with chlorhexidine (2%) allowing the skin to dry, maximal barrier precautions for inserting a catheter (sterile gloves, gown, mask, and drapes), choice of optimal insertion site, prompt catheter removal, and daily evaluation of the need for the CVC was introduced. RESULTS: The catheterization duration was longer and femoral access was more frequently observed in patients with CLABSIs. CLABSI rates decreased with use of the care bundle. The CLABSI rate in the medical ICU was 6.20/1,000 catheter days during the prior period, 3.88/1,000 catheter days during the intervention period, and 1.05/1,000 catheter days during the third period. The CLABSI rate in the surgical ICU was 8.27/1,000, 4.60/1,000, and 3.73/1,000 catheter days during these three periods, respectively. CONCLUSIONS: The choice of an optimal catheter insertion site, use of all barrier precautions, and removal of catheters when they are no longer needed are essential to decrease the CLABSI rate.

The frequency of the psychiatric symptoms in the patients with dyspepsia at a university hospital.

OBJECTIVE: According to the psychiatric hypothesis, the symptoms of dyspepsia may be due to depression, anxiety or a somatization disorder. We investigated the frequency of psychiatric symptoms in patients undergoing endoscopic procedures with dyspepsia, either with or without pathological findings, and compared this with control subjects without dyspeptic symptoms. METHODS: Ninety patients with dyspeptic symptoms and 90 control subjects participated in the study. Both the patients and the controls were asked to complete a questionnaire about socio-demographic characteristics, the Turkish version of the Spielberger State-Trait Anxiety Inventory (STAI) and the Symptom Check List-90 (SCL-90). In order for us to determine whether the criteria for any of the conditions listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) were met, the patients were asked to take part in the Structured Clinical Interview for DSM-IV disorders. RESULTS: Of the participants, 47.8% had a psychiatric disorder according to DSM-IV criteria, somatoform disorder (44.2%) being the most common. While 42.2% patients were determined to have a pathological finding using endoscopic evaluation, 57.8% had no findings. Together with the somatization and obsessive-compulsive disorder subscale scores, the total SCL-90 score and the mean trait anxiety score were statistically significantly higher in participants with no pathological findings. There were trends for anxiety (13.2% vs. 7.7%) and mood (2.6% vs. 0.0%) disorders to be more frequent in patients with pathological findings, while somatoform disorder+depressive disorder (17.3% vs. 5.2%) was more frequent in patients with no findings, although the differences were not statistically significant (Z=0.7, P>.05). The scores of state-trait anxiety, somatization, obsession-compulsion, depression, anxiety, phobic anxiety and psychotism subscales, and the total SCL-90 score were statistically significantly higher in those participants without a pathological finding than in the controls. CONCLUSIONS: Regarding the high frequency of psychiatric disorders in patients with dyspeptic symptoms, we think that such patients should be evaluated by two separate departments, gastroenterology and psychiatry.

[Subcutaneous emphysema of the face, neck and upper mediastinum following a minor maxillofacial trauma]. / Minör maksillofasiyal travma sonrasi yüz, boyun ve üst mediastene yayilan cilt alti amfizem olgusu.

Subcutaneous emphysema is the inadvertent introduction of air into tissues under the skin covering the chest wall or neck. The common causes of subcutaneous emphysema are rib fracture, parenchymal lung wound and esophageal trauma. Rarely, it occurs after oral and nasal surgery or maxillofacial trauma. We observed subcutaneous emphysema spread out from periorbital region to upper mediastinum in a patient presented to em e rgency department following minor maxillofacial trauma and admitted due to a simple fracture at his frontal maxillary wall. We present this present case to emphasize early initial management and close observation of minor facial traumas which can prevent further unexpected complications.

In acute organophosphate poisoning, the efficacy of hemoperfusion on clinical status and mortality.

The aims of this study were to report experience in patients with organophosphate poisoning (OPP) and to discuss the potential role for hemoperfusion (HP) in the management of severe OPP. At the emergency service of a university hospital, 52 patients with acute OPP were included in this retrospective study. The patients were divided into 2 groups (Group 1, severe poisoning, n = 25; and Group 2, mild poisoning, n = 27). All patients with mild OPP survived. Seven patients (28%) of the 25 with severe OPP died. This study supports previous data documenting that HP is unnecessary in the management of mild OPP. Although there was not a control group (severe poisoning without HP treatment) in this study, experience suggests that HP can be useful in severe cases. Reports from centers having experience with severe OPP can help clarify this controversial issue. Randomized controlled (prospective) studies investigating the possible beneficial effects of HP on patient survival in patients with severe OPP with control group are needed.

Posttraumatic pneumocephalus-induced bilateral oculomotor nerve palsy.

Bilateral third nerve palsy often points to the involvement of its nucleus. Third nerve palsy as a result of posttraumatic nuclear involvement is an extremely rare condition. A 23-year-old man presented with a depressed skull fracture after acute head trauma and had Glasgow Coma Scale Score of 9. The diameters of the pupils were 6.5 and 7.5 mm and they were not reactive to light stimulation. There was bilateral ptosis. Computed tomography (CT) relieved bilateral perimesensephalic pneumocephalus. We suggested that bilateral oculomotor nerve paresis might develop in association with posttraumatic bilateral perimesensephalic pneumocephalus, which affected the nucleus of the third nerve.

Retrospective evaluation of emergency service patients with poisoning: a 3-year study.

The purpose of this retrospective study was to evaluate the characteristics of cases of acute poisoning in adults who were admitted to emergency service over a 3-year period. Clinical charts were analyzed retrospectively for etiologic and demographic patient characteristics. A total of 810 adults were admitted to the emergency center with acute poisoning. The female-to-male ratio was 2:1. Mean ages of female and male patients were 28.8+/-12.9 years and 35.1+/-15.4 years, respectively, and many patients (46.9%) were between the ages of 16 and 25 years. Medicinal drugs were found to be the primary cause (60.5%) of poisoning, and tricyclic antidepressants were the most frequent causative agents (36.3%). Seasonal distribution of poisoning cases suggested a peak in the summer months (35.4%). Overall, 68.6% of acute poisonings were suicide attempts, and of these patients, 84.9%, 14%, and 1.1% were attempting suicide for the first, second, and third times, respectively. Among 810 cases of acute poisoning, 15 were fatal. The following conclusions were reached by investigators: (1) in the test region, younger females, especially single females, were at greater risk for poisoning than other patient groups, (2) self-poisoning cases constituted the majority of all poisonings, and (3) the main agents of self-poisoning were medicinal drugs, with antidepressants used most frequently. It was also found that unintentional poisoning commonly resulted from intake of foods, especially mushrooms.

Conversion and somatization disorders; dissociative symptoms and other characteristics.

OBJECTIVE: There is a difference in classification of conversion disorder in ICD-10 and DSM-IV. Conversion disorder is included in dissociative disorders in ICD-10. In view of this, we aimed to clarify this discrepancy in the classification of this diagnosis. METHODS: We assessed 87 patients with conversion disorder and 71 patients with somatization disorder for sociodemographic characteristics, suicide ideation, psychiatric symptoms and dissociative symptoms using the Patient Information Form, the Dissociative Experience Scale (DES), the Symptom Check List (SCL-90-R) and the Suicide Ideation Scale. RESULTS: The number of the high school graduates, singles and students with conversion disorders was higher than the number of patients with the same characteristics who have somatization disorder. In conversion disorder, the SCL-90-R total score and the score in paranoid ideation, psychoticism subgroups were higher than the scores in somatization disorders. There were no statistical differences in suicide ideation and the total score of dissociative symptoms between the two disorders. The number of patients whose total DES score of 30 and above was higher in conversion disorders. DISCUSSION: As a result of this present study, we concluded that to enlighten the concepts of conversion, further somatization and dissociation studies are necessary.

Conversion disorder and its subtypes: a need for a reclassification.

Four subtypes of conversion disorder were described in DSM-IV. There are few publications concerning studies aimed at separating the subtypes of the conversion disorder. Usually, pseudoseizures are in focus and attempts are made to differentiate these seizures from other disorders. The aim of the present study has been to investigate differences between the four subtypes of the conversion disorder and to discuss the possibilities for a reclassification. Ninety-five patients were seen by two researchers and diagnosed as conversion disorders. The subtypes were determined according to DSM-IV criteria. All completed the Patients Information Form, developed by the researchers, and the Dissociative Experience Scale (DES). Twenty-four (25.2%) of the patients had motor symptoms or deficits (Type 1), 5 (5.2%) sensory symptoms or deficits (Type 2), 23 (24.2%) seizures or convulsions (Type 3) and 43 (47.3%) had mixed presentations (Type 4). There were statistically significant differences between the subtypes as concerns occupation, family history of psychiatric disorders, hospitalizations and place of settlement. Furthermore, the DES scores were statistically different between the groups of patients with different subtypes of conversion disorder.

Climatic and diurnal variation in suicide attempts in the ED.

The aim of this study was to determine whether there is a relationship between climatic factors and suicidal behavior. A total of 1,119 suicide attempts were collected from hospital records between 1996 and 2001. A clear seasonal variation was seen in suicide attempts in the 15-24, 25-34, and over 65 age groups in men and in the 15-24, 25-34, and 35-44 age groups in women with peaks in the spring and summer. Suicide attempts were more frequent between the hours of 6:00-9:00 pm in males and 3:00-6:00 pm in females. People attempting suicide who have depression, anxiety, or a psychotic disorder usually attempt suicide in the summer. Whereas the monthly averages of humidity, ambient temperature, duration and intensity of sunlight were positively correlated with the number of monthly suicide attempts, cloudiness and atmospheric pressure were negatively correlated. In conclusion, we must keep in mind that suicides and suicide attempts are not only the effect of climatic changes and that the most important component is the individual's ability to deal with conflicts.

[The incidence of pathologic findings of the cranial computed tomography in patients with minor head trauma and its correlation with age and clinical features]. / Hafif kafa travmali olgularin kraniyal tomografisindeki patolojik bulgu sikiliginin yas gruplari ve klinik ile korelasyonu.

BACKGROUND: Our objective was to determine the incidence of diagnosing lesions by cranial computed tomography (CT) and to evaluate prospectively whether this incidence correlated with clinical features and age in patients with minor head trauma (MHT). METHODS: This prospective study included 78 patients with MHT. All of the cases underwent CT following their clinical assessment. RESULTS: In the 34.61% of cases, there was a pathologic finding in the CT however the incidence of intracranial injury was 15.38%. There were no significant differences between children (n:22) and adults (n:56), the patients with and without a history of the loss of consciousness/amnesia and the patients with and without clinical symptoms (p>0.05). CONCLUSION: Our results support the studies which have reported that there is no non-focal clinical factor as a predictor for pathologic CT findings.
