Analgesic efficacy of the serratus anterior plane block in rib fractures pain: A randomized controlled trial.

BACKGROUND: Serratus anterior plane block (SAPB) was evaluated that in patients with the complaint of rib fracture pain in terms of total analgesic consumption and pain scores. METHOD: Sixty patients with rib fracture and NRS (Numeric Rating Scala) pain scores equal or greater than four were included in randomized controlled study. Patients were randomized to perform SAPB or control group. Primary outcome was total tramadol consumption in 24 h. Secondary outcomes were NRS scores (after Patient Controlled Analgesia (PCA) application 30 min, first, second, 4 th, 6 th, 12 th, 24 th hour), peripheral oxygen saturation (first and 24 th hour after PCA application), chronic pain. and complications. RESULTS: The total tramadol consumption significantly lower in group S (p = 0.02). NRS scores after 30 min, 1 h, 2 h, 4 h, 6 h, 12 h, and 24 h were significantly lower in group S than in group C (p < 0.001, p < 0.001, p < 0.001, p < 0.001, p = 0.002, p = 0.026). The total number of patients who reported of chronic pain at rest and during effort was significantly lower in group SAPB than in group C (p = 0.006). Nine patients in group C were reported of pain, four of whom had pain at rest and five had pain during effort. One patient in group S was reported of pain during effort. CONCLUSION: This study demonstrated that SAPB, as part of multimodal analgesia in pain management due to rib fractures, is safe and effective in reducing acute pain.

Assessment of Somatic Support Process for Pregnant Brain Death Patients Occurring in a Transition Country Between Asia and Europe from Medical, Ethical, Legal and Religious Aspects.

In spite of the fact that brain death during pregnancy is not a common occurrence, it is an important ethical problem for all cultures and religions can have a significant influence on the donation decision after brain death. Therefore, this study aimed to present the case of a pregnant patient developing brain death which occurred in our intensive care unit and to compare the medical, ethical and legal problems relating to pregnant cases developing brain death with 24 cases in the literature. A 21-year-old 19-week pregnant case with gestational diabetes was monitored in the anesthesia intensive care unit and developed brain death due to intracranial mass and intraventricular hemorrhage. Though brain death is a situation well understood by organ transplant professionals, brain death developing in pregnant patients still involves many medical, ethical and legal problems.

Low-flow anaesthesia with a fixed fresh gas flow rate.

During the wash-in period in low flow anaesthesia (LFA), high fresh gas flow is used to achieve the desired agent concentration. In this study, we aimed to evaluate the safety of fixed 1 L/min fresh gas flow desflurane anaesthesia in both the wash-in and maintenance periods in patients including the obese ones. 104 patients undergoing surgery under general anaesthesia were included. After endotracheal intubation, fresh gas flow was reduced to 1 L/min and the desflurane vaporizer was set at 18%. The time from opening the vaporizer to end-tidal desflurane concentration reaching 0.7 MAC was recorded (MAC 0.7 time). Throughout the surgery, hemodynamic variables, FIO2, MAC and BIS values were observed. MAC 0.7 time, BIS and MAC values at the start of surgery, number of adjustments in vaporizer settings, desflurane consumption were recorded. The average MAC 0.7 time was 2.9 ± 0.5 min. MAC and BIS values at the start of the surgery were 0.7 (0.6-0.8) and 39 ± 8.5 respectively. No individual patient had a BIS value above 60 throughout the surgery. Hemodynamic variables were stable and FIO2 did not fall below 30% in any patient. The number of adjustments in vaporizer settings was 56. Average desflurane consumption was 0.33 ± 0.05 mL/min. We demonstrated that LFA without use of initial high fresh gas flow during the wash-in period is an effective, safe and economic method which is easy to perform.

Extracorporeal carbondioxide removal (ECCO2R): case series and review of literature.

INTRODUCTION: Ventilation treatment has proven success in acute respiratory distress syndrome (ARDS), while it still remains a challenge to utilize it with lower tidal volumes especially in subjects with respiratory acidosis. The concept of supporting conventional ventilation with extracorporeal carbondioxide removal (ECCO2R) may contribute in adjusting respiratory acidosis consequent to tidal volume reduction in protective ventilation setting. This method allows an easier management of ARDS due to its less invasive approach. As shown by recent studies, ECCO2R can be preferred in subjects with exacerbation of chronic obstructive pulmonary disease (COPD) who are unresponsive to non-invasive ventilation (NIV). One of the most important aspects of this can be stated as the reduced rate of endotracheal intubation. MATERIALS AND METHODS: Subjects that were admitted to intensive care unit between March 2014 to November 2015 due to hypercapnic respiratory failure were treated using ECCO2R. RESULT: Over the study period, five patients received ECCO2R therapy. All subjects were managed with ECCO2R (Hemolung, A Lung Inc., Pittsburgh, USA) via a 15.5 FG percutaneously inserted cannula. CONCLUSIONS: We observed that ECCO2R is a promising method in the management of patients having COPD and can be used to protect lungs in patients with ARDS.

Efficacy of bispectral index monitoring for prevention of anestheticawareness and complications during oocyte pick-up procedure

Background/aim: This study was planned by considering that the use of bispectral index (BIS) monitoring ensures sufficient depth of anesthesia and avoids anesthetic awareness and patient movement in the oocyte pick-up (OPU) procedure.Materials and methods: Ninety-eight patients undergoing OPU were randomly divided into 2 groups as the control group (n = 48) and BIS group (n = 50). After propofol and remifentanil induction, the control group was given additional propofol according to reaction response, while the BIS group was given propofol at BIS values of 60 and above with the aim that BIS values be 40?60. Total procedure time, recovery time, patient movement, additional propofol consumption, total number of oocytes, and awareness during anesthesia were recorded. Results: Demographic data were similar in the two groups (P > 0.05 for all). The recovery time in the BIS group was significantly shorter compared to the control group (P < 0.001) while additional propofol consumption was found to be significantly lower (P < 0.001). Baseline BIS values fell compared to all other times after induction significantly (P < 0.001). No patient had anesthesia awareness.Conclusion: During the OPU procedure BIS monitoring is considered to prevent anesthesia awareness, intraoperative movement, and complications caused by insufficient anesthetic use as it ensures optimal doses of anesthetic agents used and early recovery.

Removal of extracorporeal carbon dioxide in chronic obstructive pulmonary disease patients.

The use of invasive mechanical ventilation (IMV) procedures in chronic obstructive pulmonary disease (COPD) patients suffering from episodes of acute exacerbation are associated with high rates of mortality. In this case study, we describe the use of a new device for extracorporeal carbon dioxide removal (ECCO2R) that can provide partial respiratory support for patients where noninvasive ventilation (NIV) proved insufficient. The case described in this manuscript represents the first clinical feasibility study for the Hemolung device, and was also the first use and application of the device at our department.

The interrelations of radiologic findings and mechanical ventilation in community acquired pneumonia patients admitted to the intensive care unit: a multicentre retrospective study.

BACKGROUND: We evaluated patients admitted to the intensive care units with the diagnosis of community acquired pneumonia (CAP) regarding initial radiographic findings. METHODS: A multicenter retrospective study was held. Chest x ray (CXR) and computerized tomography (CT) findings and also their associations with the need of ventilator support were evaluated. RESULTS: A total of 388 patients were enrolled. Consolidation was the main finding on CXR (89%) and CT (80%) examinations. Of all, 45% had multi-lobar involvement. Bilateral involvement was found in 40% and 44% on CXR and CT respectively. Abscesses and cavitations were rarely found. The highest correlation between CT and CXR findings was observed for interstitial involvement. More than 80% of patients needed ventilator support. Noninvasive mechanical ventilation (NIV) requirement was seen to be more common in those with multi-lobar involvement on CXR as 2.4-fold and consolidation on CT as 47-fold compared with those who do not have these findings. Invasive mechanical ventilation (IMV) need increased 8-fold in patients with multi-lobar involvement on CT. CONCLUSION: CXR and CT findings correlate up to a limit in terms of interstitial involvement but not in high percentages in other findings. CAP patients who are admitted to the ICU are severe cases frequently requiring ventilator support. Initial CT and CXR findings may indicate the need for ventilator support, but the assumed ongoing real practice is important and the value of radiologic evaluation beyond clinical findings to predict the mechanical ventilation need is subject for further evaluation with large patient series.

The effect of lavender aromatherapy on the level of intraoperative anxiety in caesarean case under spinal anesthesia: A randomized controlled trial.

BACKGROUND: Preoperative anxiety can be reduced by aromatherapy. This study aimed to evaluate the effect of lavender aromatherapy in reducing intraoperative anxiety in patients undergoing caesarean section (CS) under spinal anesthesia. METHODS: This study was two-armed and randomized controlled trial. A total of 96 patients who were scheduled for CS were randomly divided into two groups: the aromatherapy (A) group (n=48), comprising patients who were randomized to receive lavender aromatherapy with mask oxygen after the birth of the baby, and the control (C) group (n=48), comprising patients who inhaled carrier oil. During the preoperative period, baseline anxiety levels and Visual Analog Scale (VAS) pain scores were recorded using the State-Trait Anxiety Inventory (STAI-I) scale. After birth, two drops of oil were inhaled in an oxygen mask for 5 min. After 5 min, the Ramsey Sedation Scale was evaluated, and patients with a score of 1 received 2 mg of intravenous midazolam for sedation. The STAI-I and VAS pain scores were re-evaluated at the third postoperative hour. RESULTS: The primary outcome was the significant reduction in the need for midazolam brought about by lavender aromatherapy, and the secondary outcomes included postoperative third-hour STAI-I scores, intraoperative complications and patient satisfaction. CONCLUSION: The effectiveness of lavender aromatherapy, which reduced the need for intraoperative anxiolytics, can be offered as an alternative for pregnant women who undergo CS under spinal anesthesia.

Comparison of the postoperative analgesic effect of transversus abdominis plan block and quadratus lumborum block: A prospective randomized study.

Background and Aims: In this study, we aimed to compare the transversus abdominis plan block (TAP) and quadratus lumborum block (QL) efficacy for postoperative analgesia in patients undergoing varicocelectomy under spinal anesthesia. Methods: American Society of Anesthesiologists (ASA) 1 and 2 patients, aged 18-45 years, who underwent varicocelectomy operation under elective conditions, were included. Eighty patients were divided into three groups as TAP group, QL group, and control group by prospective randomization. The patients were operated under spinal anesthesia. At the end of the operation, TAP was applied to the TAP group with a posterior approach using ultrasound (USG) in the supine position. To the QL group, the patient was placed in the lateral decubitus position and the lateral QL was applied via USG. No block type was applied to the control group. Patient-controlled analgesia (PCA) device containing tramadol was administered intravenously at the end of the surgery in all groups. Visual analogue scale (VAS) score was questioned at 0, 2, 4, 6, 8, 10, 12, 18, 24 h in the follow-up of the patients. Intravenous 1 g paracetamol was given over VAS 4. PCA usage time and usage amounts were recorded. Results: As a result of comparing the groups according to the VAS scores at all hours were significantly different between the three groups (p < 0.001). There was a significant difference between the groups when comparing the number of PCA bolus administrations (p < 0.001). TAP and QL blocks significantly reduced the number of PCA bolus when compared with the control group (p < 0.001) but the number of PCA bolus was found to be similar between TAP and QL blocks (p > 0.05). Conclusion: TAP and QL, which are administered to evaluate the effectiveness of postoperative analgesia in patients undergoing varicocelectomy under spinal anesthesia, are both effective in reducing pain scores and the amount of analgesia consumption.

Effects of enflurane and propofol on seizure duration and recovery profiles in electroconvulsive therapy.

UNLABELLED: The aim of this study is to investigate effect of enflurane that is a pro-convulsive anesthetic agent and propofol on seizure durations and recovery times during electroconvulsive therapy. METHODS: The subjects were divided into two groups according to the induction anesthetics. Anesthesia was induced with enflurane 5% in group E or propofol 1.2 mg x kg(-1) in group P. After the loss of consciousness, 0.5 mg x kg(-1) of succinylcholine was given. The patients maintained normocapnia. RESULTS: There were no significant differences between groups regarding seizure times. Recovery times were shorter in group E, but postictal agitation was significantly lower in propofol group. DISCUSSION: High incidence of spike activity on EEG and grand mal seizure patterns could be induced by enflurane. But motor and EEG seizure times were not prolonged by enflurane in the presence normocapnia. In conclusion, propofol is more suitable anesthetic agent for ECT, but enflurane might be preferred in patients because of rapid recovery.

Compliance With the Surviving Sepsis Campaign Bundle: A Multicenter Study From Turkey.

Objectives Sepsis bundle compliance is not clear. We evaluated rates of compliance with sepsis bundle protocols among health care providers in Turkey. Methods Our study was carried out retrospectively. Forty-five intensive care units (ICU) participated in this study between March 2, 2018 and October 1, 2018. Results One hundred thirty-eight ICUs were contacted and 45 ICUs agreed to participate. The time taken for the diagnosis of sepsis was less than six hours in 384 (59.8%) patients, while it was more than six hours in 258 (40.2%) patients. The median [interquartile range (IQR)] times for initial antibiotic administration, culturing, vasopressor initiation, and second lactate measurement were 120.0 (60-300) minutes, 24 (12-240) minutes, 40 (20-60) minutes, and 24 (18-24) hours, respectively. The rate of compliance with tissue and organ perfusion follow-up in the first six hours was 0%. The rates of three- and six-hour sepsis bundle protocol compliance were both 0%. The ICU mortality rates for sepsis and septic shock were 22% and 78%, respectively. The ICU mortality rates for sepsis and septic shock were 22% and 78%, respectively. Conclusions The rate of compliance with sepsis bundle protocols was evaluated in Turkey for the first time and determined to be 0%.

Effects of Propofol versus Sevoflurane on Postoperative Pain and Neuroendocrine Stress Response in Oocyte Pickup Patients.

Background: Pain aggravates the autonomic response to stress and raises neuroendocrine stress hormone levels. We compared the effects of propofol and sevoflurane on postoperative pain and neuroendocrine stress hormones. A prospective, randomized, and controlled trial was conducted with 60 patients. Methods: We randomly allocated patients to groups P (remifentanil/propofol, n = 30) and S (remifentanil/sevoflurane, n = 30). Preoperative blood samples were taken to measure serum adrenocorticotropic hormone (ACTH), corticotropin-releasing hormone (CRH), glucagon, cortisol, aldosterone, and prostaglandin E2 (PGE2) levels. Intraoperatively and postoperatively, clinical parameters were monitored at different time points. The hormone levels were again measured in the follicular fluid and blood postoperatively. Result: Demographic data were similar. The preoperative serum aldosterone levels were significantly higher in group P (p=0.001). Preoperative and postoperative serum ACTH, glucagon, cortisol, and PGE2 levels were significantly different in group P (p=0.009, p=0.004, p=0.029, and p=0.002); serum ACTH, glucagon, and PGE2 levels increased while serum cortisol levels decreased postoperatively. In group S, serum CRH and aldosterone levels, both increased in the postoperative period compared to the preoperative (p=0.001, p=0.006). Postoperatively, glucagon and PGE2 levels were both higher in group P than group S (p=0.019, p=0.015). In postoperative follicular fluid, glucagon and PGE2 levels were higher in group P, while cortisol levels were higher in group S (p=0.001, p=0.007, and p=0.001). Conclusion: The effects of anesthetic agents were different. In group P, in the preoperative and postoperative evaluation, ACTH, glucagon, and PGE2 increased postoperatively, while cortisol decreased. In group S, aldosterone and CRH increased postoperatively. Glucagon and PG E2 were higher in group P than S, postoperatively.

Evaluation of the incidence, characteristics, and outcomes of pediatric chronic critical illness.

Our aim was to determine characteristics of children with chronic critical illness (CCI) admitted to the pediatric intensive care unit (PICU) of a tertiary care children's hospital in Turkey. The current study was a multicenter retrospective cohort study that was done from 2014 to 2017. It involved three university hospitals PICUs in which multiple criteria were set to identify pediatric CCIs. Pediatric patients staying in the ICU for at least 14 days and having at least one additional criterion, including prolonged mechanical ventilation, tracheostomy, sepsis, severe wound (burn) or trauma, encephalopathy, traumatic brain injury, status epilepticus, being postoperative, and neuromuscular disease, was accepted as CCI. In order to identify the newborn as a chronic critical patient, a stay in the intensive care unit for at least 30 days in addition to prematurity was required. Eight hundred eighty seven (11.14%) of the patients who were admitted to the PICU met the definition of CCI and 775 of them (87.3%) were discharged to their home. Of CCI patients, 289 (32.6%) were premature and 678 (76.4%) had prolonged mechanical ventilation. The total cost values for 2017 were statistically higher than the other years. As the length of ICU stay increased, the costs also increased. Interestingly, high incidence rates were observed for PCCI in our hospitals and these patients occupied 38.01% of the intensive care bed capacity. In conclusion, we observed that prematurity and prolonged mechanical ventilation increase the length of ICU stay, which also increased the costs. More work is needed to better understand PCCI.

Ischemia-reperfusion injury in skeletal muscle: comparison of the effects of subanesthetic doses of ketamine, propofol, and etomidate.

BACKGROUND: Interest in the effects of anesthetics in skeletal ischemia-reperfusion injury (IRI) has recently emerged. Thus, the objective was to compare the effects of subanesthetic doses of ketamine, propofol, and etomidate in a skeletal IRI model. METHODS: IRI was applied to rats by tourniquet method. Under thiopental anesthesia, five experimental groups were established as follows: (1) sham-control, (2) IRI, (3) IRI+Ketamine, (4) IRI+Propofol, and (5) IRI+Etomidate. Malondialdehyde, superoxide dismutase, catalase, and glutathione peroxidase were measured in skeletal muscle via a spectrophotometer. Zinc, iron, copper, and selenium were evaluated by atomic absorption spectrophotometer. RESULTS: While the values of malondialdehyde and glutathione peroxidase were higher and lower, respectively, those of superoxide dismutase and catalase were identical in IRI group in comparison with sham-control. Zinc displayed a decrease in IRI group; however, no differences in iron and copper levels were determined. In rats treated with subanesthetic doses of ketamine, elevated malondialdehyde levels in IRI group were reversed to control levels by each dose. While each dose of ketamine decreased superoxide dismutase activities in comparison with IRI group, a reduction in catalase activity was only seen in 3mg/kg ketamine-treated rats. The attenuated glutathione peroxidase activity seen in IRI was greatly reversed by ketamine administration in all doses. No differences in zinc, copper, and iron levels were detected between IRI and ketamine-treated groups. Similar results were obtained either by the administration of propofol or etomidate. CONCLUSIONS: Subanesthetic doses of ketamine, propofol and etomidate displayed beneficial effects in IRI.

Thiopental improves renal ischemia-reperfusion injury.

UNLABELLED: Ischemia/reperfusion (I/R) occurs in a number of pathological conditions, including myocardial infarction, stroke, aortic surgery, cardiopulmonary bypass surgery, organ transplantation, resuscitation, and critical care. Massive and abrupt release of oxygen-free radicals after reperfusion triggers oxidative damage. Before critical operations or after resuscitation, it would be wise to find a suitable prophylactic treatment to avoid I/R damage. We aimed to determine whether several commonly used intravenous anesthetics protect against renal I/R injury. METHODS: Animals were randomly divided into seven groups, each consisting of six animals: sham group, control group, thiopental group, propofol group, intralipid group, etomidate group, and ketamine group. At the end of the 60-min ischemic period, 60 min reperfusion was established and the materials administered 15 min before the reperfusion. At the end of the reperfusion period, the samples of blood and tissue were reaped for biochemical and serological evaluation. RESULTS: I/R procedure significantly increased malondialdehyde (MDA) levels, decreased catalase (CAT) activities, and superoxide dismutase (SOD) levels. The lowest MDA mean level was in the thiopental group and the highest MDA mean level was in control group. The lowest CAT mean level was in the intralipid group and the highest CAT mean level was in the etomidate group. The lowest SOD mean level was in the control group and the highest SOD mean level was in the propofol group. CONCLUSION: Thiopental and propofol, especially thiopental, are more effective to protect renal I/R injury.

Sedation during noninvasive mechanical ventilation with dexmedetomidine or midazolam: A randomized, double-blind, prospective study.

BACKGROUND: Effective noninvasive mechanical ventilation (NIV) requires a patient to be comfortable and in synch with the ventilator, for which sedation is usually needed. Choice of the proper drug for sedation can lead to improved clinical outcomes. OBJECTIVE: The aim of this study was to compare the effectiveness of dexmedetomidine and midazolam on sedation and their effects on hemodynamics and gas exchange. METHODS: In this randomized, double-blind study, intensive care unit patients with acute respiratory failure due to acute exacerbations of chronic obstructive pulmonary disease undergoing NIV were equally randomized to receive a loading dose of 1 µg/kg IV dexmedetomidine or 0.05 µg/kg midazolam over 10 minutes followed by a maintenance infusion of 0.5 µg/kg/h dexmedetomidine (group D) or 0.1 mg/kg/h midazolam (group M). The following parameters were measured by a blinded clinician at baseline and 1, 2, 4, 6, 8, 12, and 24 hours after the loading dose was administered: Ramsay Sedation Score (RSS), Riker Sedation-Agitation Scale (RSAS), Bispectral Index (BIS), arterial blood gases, and vital signs. A second blinded investigator determined dosing changes according to the outcome of maintaining a target sedation level of RSS 2 to 3, RSAS 3 to 4, and BIS >85. RESULTS: A total of 45 patients were assessed for enrollment in the study; 4 did not meet the inclusion criteria and 1 refused to participate (men/women 19/21; mean age 58/60; all patients were receiving bronchodilators, steroids, antibiotics, and mucolytics). In both groups (n = 20), RSS significantly increased and RSAS levels and BIS values significantly decreased after the loading dose, compared with baseline (P < 0.05). RSS levels were significantly lower beginning at 4 hours in group D compared with group M (P < 0.05). RSAS levels were not significantly different between the 2 groups in the first 8 hours. However, RSAS levels were significantly higher at 8 hours after the loading dose was administered in group D compared with group M (P < 0.01). BIS was significantly higher in group D throughout the study period (P < 0.05). Respiratory rates and gas exchange values were not significantly different between the Accepted for publication April 7, 2010. 2 groups. The number of times a change in infusion dose was needed was significantly lower in group D (2 patients with 1 change each) than in group M (3 patients with 1 change, 1 patient with 2 changes, and 3 patients with 3 changes each) (P < 0.01). CONCLUSIONS: Dexmedetomidine and midazolam are both effective sedatives for patients with NIV. Dexmedetomidine required fewer adjustments in dosing compared with midazolam to maintain adequate sedation.

Protective effects of propofol on peritoneal adhesions in cecal ligation and puncture model.

AIM: We assumed that one of the most widely used anesthetic agents, propofol, which is the most widely used anesthetic for sedation, may reduce inflammatory processes and organ injury induced by cecal ligation and puncture. STUDY DESIGN: Bacterial peritonitis was induced in 18 rats by cecal ligation and puncture. The rats were randomly assigned to three groups. Group 1 (n=6) received propofol, group 2 (n=6) received intralipid, group 3 (n=6) was a control group, which did not receive any injection. All animals were killed 14 days later so we could assess the adhesion score. Tissue antioxidant levels were measured in 1-g tissue samples taken from the abdominal wall. RESULTS: The adhesion score was significantly lower in the propofol group than in the control group (p<0.05). The catalase levels were higher in the intralipid and control groups than the propofol groups. CONCLUSIONS: Intraperitoneal propofol reduced the formation of postoperative intra-abdominal adhesions without compromising wound healing in this bacterial peritonitis rat model. Propofol also decreased the oxidative stress during peritonitis (Tab. 1, Fig. 5, Ref. 28). Full Text (Free, PDF) www.bmj.sk.

Comparison of the efficacy of surgical tracheostomy and percutaneous dilatational tracheostomy with flexible lightwand and ultrasonography in geriatric intensive care patients.

AIM: To compare the applicability, technical difficulties and postoperative complications of surgical tracheostomy and percutaneous dilatational tracheostomy with the flexible lightwand + ultrasonography method applied because of prolonged intubation to geriatric patients in the intensive care unit. METHODS: A retrospective evaluation was made of 76 patients who received surgical tracheostomy (group 1) and 78 patients who received percutaneous dilatational tracheostomy (group 2). The patients were evaluated in respect of demographic data, duration of intubation, length of stay in the intensive care unit and discharge status, and after the intervention, the development of tube-related complications, early stage local complications and late-stage complications. RESULTS: The time from intubation to tracheostomy was determined as 22.73 ± 15.23 days in group 1 and 12.65 ± 7.64 days in group 2. The mortality rate of patients in group 1 was determined to be statistically significantly higher than that of group 2 (P = 0.048). When evaluated in respect to early and late complications, nine early- and seven late-stage complications developed in group 1, and three early- and three late-stage complications developed in group 2 (P = 0.05). In the evaluation of factors related to mortality, the time from intubation to tracheostomy (r = 0.249, P = 0.01) and the presence of a comorbidity (r = 0.325, P = 0.004) were determined to have a positive correlation with the development of mortality. CONCLUSION: Percutaneous dilatational tracheostomy with the flexible lightwand + ultrasonography technique is a safe, rapid and effective method with the advantage of management in respect to early complications, such as bleeding, and can be used safely in the geriatric patient population in intensive care conditions.

Are high fresh gas flow rates necessary during the wash-in period in low-flow anesthesia?

In low-flow anesthesia (LFA), there is a wash-in period in which usually high fresh gas flow (FGF) rates are used to achieve the required initial concentration of anesthetic agent in the alveoli. The aim of this study was to compare the efficiency, safety and the consumption of desflurane in LFA using constant FGF (1 L/min) and conventional LFA using high FGF (4 L/min) during the wash-in period. Eighty patients, who were scheduled for elective surgery under general anesthesia with endotracheal intubation, were enrolled in the study. Wash-in was accomplished with 1 L/min FGF (50% O2, 50% air) and 18% desflurane in group 1; and by 4 L/min FGF (50% O2, 50% air) and 6% desflurane in group 2. Throughout the surgery, the vaporizer was adjusted to maintain 0.6 to 0.8 minimum alveolar concentration (MAC). The time required to reach 0.7 MAC was shorter in group 1 (160 seconds [135-181] vs 288 seconds [240-500], P < .001). In 6 patients in group 1 and 13 in group 2, vaporizer settings were adjusted to maintain 0.6 to 0.8 MAC (P = .048). Desflurane consumption in the first hour and total desflurane consumption were higher in group 2 (P < .001 and P = .012, respectively). The efficiency of anesthesia in both the first hour and in total was higher in group 1 (P < .001). It is safe, more efficient, and economical to use 1 L/min FGF during the wash-in period in LFA.

Retrospective Evaluation of Anesthetic Management in Cesarean Sections of Pregnant Women with Placental Anomaly.

BACKGROUND: In this study, patients who underwent cesarean section and had placenta previa and placenta accreta were examined and compared in terms of haemorrhagic indicators and perioperative anesthetic management. METHODS: A retrospective study was conducted in a university hospital in Kahramanmaras, Turkey. It included 95 pregnant women who had placental anomaly and underwent cesarean section between December 15, 2014, and February 15, 2016. RESULTS: The pregnant women were divided into two groups: Group P (previa) (n = 67) and Group A (accreta) (n = 28). The types of anesthesia administered were general anesthesia (GA), which was administered to 50 patients (74.6%) in Group P and 27 patients (96.4%) in Group A, and spinal anesthesia (SA), which was administered to 17 patients (25.4%) in Group P and one patient (3.6%) in Group A.. The mean blood loss was 685.82 ± 262.82 in Group P and 1582.14 ± 790.71 in Group A, and the given amount of crystalloid was higher in Group A with an average of 1628.57 ± 728.19 ml. The use of erythrocyte and fresh frozen plasma solution was higher in Group A than Group P. Eleven patients were intubated and taken to the Intensive Care Unit (ICU) in Group A. Postoperative mechanical ventilation duration was significantly higher in Group A (75.14 ± 43.84 h) (p < 0.001). ICU stay was longer in Group A with 2.80 ± 1.13 days. (p < 0.001). CONCLUSION: The intraoperative management and the availability of postoperative ICU conditions are important in placental anomalies cases. The communication between operation team with regard to the development of a standard protocol for these cases will be of great benefit in reducing morbidity and mortality.
