A novel comparison of erector spinae plane block and paravertebral block in laparoscopic cholecystectomy.

OBJECTIVE: Erector spinae plane block is an updated method than paravertebral block, possessing a lower risk of complications. This study aimed to compare erector spinae plane and paravertebral blocks to safely reach the most efficacious analgesia procedure in laparoscopic cholecystectomy cases. METHODS: The study included 90 cases, aged 18-70 years, classified as American Society of Anesthesiologists I-II, who underwent an laparoscopic cholecystectomy procedure. They were randomly separated into three groups, namely, Control, erector spinae plane, and paravertebral block. No block procedure was applied to Control, and a patient-controlled analgesia device was prepared containing tramadol at a 10 mg bolus dose and a 10-min locked period. The pain scores were recorded with a visual analog scale for 24 h postoperatively. RESULTS: The visual analog scale values at 1, 5, 10, 20, and 60 min at rest and 60 min coughing were found to be significantly higher in Control than in paravertebral block. A significant difference was revealed between Control vs. paravertebral block and paravertebral block vs. erector spinae plane in terms of total tramadol consumption (p=0.006). Total tramadol consumption in the first postoperative 24 h was significantly reduced in the paravertebral block compared with the Control and erector spinae plane groups. CONCLUSION: Sonography-guided-paravertebral block provides sufficient postoperative analgesia in laparoscopic cholecystectomy surgery. Erector spinae plane seems to attenuate total tramadol consumption.

Comparison of the Effects of Sevoflurane and Desflurane on Thiol-Disulfide Homeostasis in Patients Undergoing Laparoscopic Cholecystectomy.

OBJECTIVE: This study aims to compare the effects of different inhalation anesthetics on oxidative status by measuring thiol-disulfide homeostasis in laparoscopic cholecystectomy surgeries. The effect of inhaler agents on thiol-disulfide homeostasis that shows the oxidative status in laparoscopic cholecystectomy is unknown. MATERIALS AND METHODS: In this study, 71 patients planned to undergo laparoscopic cholecystectomy under general anesthesia were included. They were divided into two groups: desflurane (group D, n: 35) and sevoflurane (group S, n: 36). Blood samples were taken before induction (T1), at 30th minute of insufflation (T2) (30th min of ischemia), and at 30th min postdeflation (T3) (30th min of reperfusion). The native thiols (-SH) and total thiols (-SH+ -SS) were determined. The amounts of disulfide (-SS), disulfide/native thiol percent ratios (-SS/-SH), disulfide/total thiol percent ratios (-SS/-SH+-SS), and native thiol/total thiol percent ratios (-SH/-SH+ -SS) were calculated. RESULTS: In the sevoflurane group, preoperative values and intraoperative 30th-minute SS-SH ratio were significantly reduced (p=0.017). In the desflurane group, intraoperative native thiol values and postdeflation levels significantly decreased compared to those in the preoperative values (p<0.001). CONCLUSION: We think that the usage of sevoflurane was more protective in terms of the oxidative damage occurring during laparoscopic surgery.

Comparison of endotracheal tube cuff pressure values before and after training seminar.

It is recommended that endotracheal cuff (ETTc) pressure be between 20 and 30 cm H2O. In this present study, we intend to observe average cuff pressure values in our clinic and the change in these values after the training seminar. The cuff pressure values of 200 patients intubated following general anesthesia induction in the operating theatre were measured following intubation. One hundred patients whose values were measured before the training seminar held for all physician assistants, and 100 patients whose values were measured after the training seminar were regarded as Group 1 and Group 2, respectively. Cuff pressures of both groups were recorded, and the difference between them was shown. Moreover, cuff pressure values were explored according to the working period of the physician assistants. There was no significant difference between the groups in terms of age, gender and tube diameters. Statistically significant difference was found between cuff pressure values before and after the training (p < 0.001). Average pressure measure for Group I was 54 cm H2O, while average pressure in Group II declined to 33 cm H2O. It was observed that as the working period and experience of physician assistants increased, cuff pressure values decreased, however no statistically significant different was found (p < 0.375). We believe that clinical experience does not have significant effects on cuff pressure and that training seminars held at intervals would prevent high cuff pressure values and potential complications.

An Examination of Factors Affecting the Length of Stay in a Palliative Care Center.

BACKGROUND: With the increase in elderly population, life-threatening chronic diseases are increasing, simultaneously increasing the need for palliative care centers (PCCs). OBJECTIVES: To evaluate the factors affecting the length of stay (LOS) and discharge of patients from a PCC. METHODS: A retrospective scan was made of the records of patients followed up in the PCC between January 2013 and March 2016. A record was made of patient age, gender, diagnosis, conditions/comorbidities, Glasgow Coma Scale, Karnofsky Performance Scale, LOS, prognosis (exitus or surviving), percutaneous endoscopic gastrostomy (PEG), tracheostomy, mechanical ventilator, nutrition (total parenteral nutrition [TPN] or enteral nutrition), and the results of cultures taken during stay in PCCs (blood, tracheal aspirate, urine, rectal swab, wound). Evaluation with regression analysis was made of the data related to factors thought to have a possible effect on the LOS in PCCs. RESULTS: Four hundred thirty-five patients were included in the study, comprising 58.6% men and 41.4% women with a mean age of 70.6 ± 17.2 years. The LOS was 27.2 ± 30.9 days. A total of 234 patients were discharged and 201 (46.2%) were lost to mortality in PCCs. The bacteria most isolated in cultures were Escherichia coli (28.5%) and methicillin resistant Staphylococcus aureus (MRSA) (17%). According to the results of the regression analysis, cancer, hypoxic brain, and advanced age had a negative effect on LOS and PEG, TPN, hypertension, and E. coli, Proteus, Pseudomonas, and Acinetobacter infections increased LOS. CONCLUSION: The results of this study revealed some basic factors that affect LOS in PCCs. However, there may be much variation in the data obtained with the various reasons for which this patient group is admitted to a PCC.

Long-term care hospitals in Turkey: a review.

A long-term care hospital (LTCH) is a specialized facility for patients with serious health problems who require continuous and intensive care but not comprehensive diagnostic methods. LTCHs provide prolonged complex care and wound care in the period following the acute stage of disease. When intensive care unit (ICU) stay is prolonged in the United States of America, the patients may be transferred to an LTCH. Medicare suggests hospitalization > 25 days in LTCHs. The LTC system in Europe differs from that in other non-European countries and differences are also seen among European countries. In practice, patients who need LTC in Turkey are hospitalized in ICUs. Long term care is a new concept for the Turkish health system and there are no studies on LTCHs in Turkey. A significant proportion of intensive care beds in Turkey are used for long-term hospitalized patients with complex problems. This is a clear waste of resources. The establishment of LTCHs in Turkey would prevent from this waste and provide the opportunity to increase experience of complex treatments.

Factors associated with preoperative anxiety levels of Turkish surgical patients: from a single center in Ankara.

BACKGROUND: Preoperative anxiety and stress are undoubtedly a difficult experience in patients undergoing elective surgery. These unpleasant sensations depend on several factors. The objective of this study was to evaluate the preoperative anxiety levels in a sample of Turkish population, as well as the underlying causes using the Spielberger State-Trait Anxiety Inventory (STAI anxiety) scale. METHODS: The study was conducted according to the Declaration of Helsinki and was approved by the local ethical committee. All participants gave written informed consent upon having received detailed information on the study. Upon entry in the study, state and trait anxiety questionnaires were completed by 186 patients scheduled for elective surgery. The influencing factors in regard to age, sex, educational status and others were also reported. RESULTS: There was a statistically significant positive correlation between state and trait anxiety scores in this Turkish population. While the most important predictive factors that affected state-STAI scores were age, sex and duration of sleep the night before surgery; educational status and age were the best predictors for determining the variation in trait-STAI scores. CONCLUSION: The factors affecting anxiety levels in different populations might vary among different countries. Interestingly, in this sample of Turkish population, the trait anxiety levels were found to be higher from state-anxiety levels, especially in women and less educated people. Thus, doubts about operation and anesthesia are overlooked. This could be attributed to the low to intermediate life standards of people admitted to our hospital.

Traumatic brain injury and palliative care: a retrospective analysis of 49 patients receiving palliative care during 2013-2016 in Turkey.

Traumatic brain injury (TBI), which is seen more in young adults, affects both patients and their families. The need for palliative care in TBI and the limits of the care requirement are not clear. The aim of this study was to investigate the length of stay in the palliative care center (PCC), Turkey, the status of patients at discharge, and the need for palliative care in patients with TBI. The medical records of 49 patients with TBI receiving palliative care in PCC during 2013-2016 were retrospectively collected, including age and gender of patients, the length of stay in PCC, the cause of TBI, diagnosis, Glasgow Coma Scale score, Glasgow Outcome Scale score, Karnofsky Performance Status score, mobilization status, nutrition route (oral, percutaneous endoscopic gastrostomy), pressure ulcers, and discharge status. These patients were aged 45.4 ± 20.2 years. The median length of stay in the PCC was 34.0 days. These included TBI patients had a Glasgow Coma Scale score ≤ 8, were not mobilized, received tracheostomy and percutaneous endoscopic gastrostomy nutrition, and had pressure ulcers. No difference was found between those who were discharged to their home or other places (rehabilitation centre, intensive care unit and death) in respect of mobilization, percutaneous endoscopic gastrostomy, tracheostomy and pressure ulcers. TBI patients who were followed up in PCC were determined to be relatively young patients (45.4 ± 20.2 years) with mobilization and nutrition problems and pressure ulcer formation. As TBI patients have complex health conditions that require palliative care from the time of admittance to intensive care unit, provision of palliative care services should be integrated with clinical applications.

Our Anaesthetic Experiences in Patients Undergoing Percutaneous Mitraclip Implantation.

OBJECTIVE: Percutaneous mitraclip implantation system, is a new technique developed for patients with high surgical risks. It is generally performed in a catheterisation laboratory with the guidance of fluoroscopy and transesophageal echocardiography. In this study, we aimed to share our experiences on anaesthetic in patients undergoing mitraclip implantation under general anaesthesia. METHODS: Eighty four patients with severe, symptomatic mitral insufficiency, who had undergone MitraClip implantation under general anaesthesia between July 2012 and March 2015 (54 male, 30 female; mean age: 68.5±10.2 years) were retrospectively investigated in terms of anaesthetic management. RESULTS: Of the 84 patients undergoing percutaneous mitraclip implantation under general anaesthesia, 84.5% had sodium thiopental and 75% had midazolam for anaesthesia induction. For the maintenance of anaesthesia, 57% of the patients were reported to have sevoflurane, whereas the rest had desflurane. The mean duration of the procedure and anaesthesia was 140.9±48.2 mins and 165.7±50.6 min, respectively. Seventy seven patients were transported to the intensive care unit and intubated after the procedure. The median extubation time was 3 h. Length of stay in the intensive care unit was 2 days, whereas it was 4 days for hospital stay. One patient died during the procedure and six patients died after the procedure. CONCLUSION: Percutaneous mitraclip implantation procedure is quite difficult for anaesthesiologists because of the procedure itself and the population on which the procedure is performed. The primary aim of anaesthesia management is to provide haemodynamic stability. The preoperative preparation and anaesthesia methods should be the same as for patients undergoing cardiac surgery. It is reported that as the experience regarding this subject increases, success of the procedure increases, with better protected haemodynamic stability, less inotropic and vasopressor requirement and shorter length of hospital stay.

Effects of Low-Flow Sevoflurane Anesthesia on Pulmonary Functions in Patients Undergoing Laparoscopic Abdominal Surgery.

Objective. The aim of this prospective, randomized study was to investigate the effects of low-flow sevoflurane anesthesia on the pulmonary functions in patients undergoing laparoscopic cholecystectomy. Methods. Sixty American Society of Anesthesiologists (ASA) physical status classes I and II patients scheduled for elective laparoscopic cholecystectomy were included in the study. Patients were randomly allocated to two study groups: high-flow sevoflurane anesthesia group (Group H, n = 30) and low-flow sevoflurane anesthesia group (Group L, n = 30). The fresh gas flow rate was of 4 L/min in high-flow sevoflurane anesthesia group and 1 L/min in low-flow sevoflurane anesthesia group. Heart rate (HR), mean arterial blood pressure (MABP), peripheral oxygen saturation (SpO2), and end-tidal carbon dioxide concentration (ETCO2) were recorded. Pulmonary function tests were performed before and 2, 8, and 24 hours after surgery. Results. There was no significant difference between the two groups in terms of HR, MABP, SpO2, and ETCO2. Pulmonary function test results were similar in both groups at all measurement times. Conclusions. The effects of low-flow sevoflurane anesthesia on pulmonary functions are comparable to high-flow sevoflurane anesthesia in patients undergoing laparoscopic cholecystectomy.

Perioperative outcome and cost-effectiveness of spinal versus general anesthesia for lumbar spine surgery.

BACKGROUND AND AIM: General anesthesia (GA) is the most commonly used anesthetic technique for spinal surgery. This study aimed to compare spinal anesthesia (SA) and GA in patients undergoing spinal surgery, in terms of perioperative outcome and cost effectiveness. MATERIALS AND METHODS: The study included 80 patients with ASA (American Society of Anesthesiologists) physical status I-II. The patients were randomized to receive SA (n = 40) or GA (n = 40). Heart rate (HR), mean arterial blood pressure (MABP), blood loss, duration of surgery, duration of anesthesia, surgeon satisfaction, and duration in the post-anesthesia care unit (PACU) were recorded. Postoperative analgesic requirement, nausea and vomiting (PONV), perioperative hemodynamic variables, and anesthetic costs were determined. RESULTS: HR and MABP were significantly higher in the GA group than in the SA group at the end of surgery and at PACU admission. Duration of anesthesia, surgeon satisfaction, postoperative analgesic requirement, and anesthetic costs were significantly higher in the GA group. Mean blood loss was lower in the SA group than in the GA group, but the difference was not significant. Duration of surgery, duration in the PACU, perioperative hemodynamic variables, and complications were similar in both groups. CONCLUSIONS: SA could be considered a reliable alternative to GA in patients undergoing lumber spine surgery, as it is clinically as effective as GA, but more cost effective.

Relation between mean platelet volume and severity of atherosclerosis in patients with acute coronary syndromes.

Platelets play a central role in the pathophysiology of coronary artery disease (CAD). Increased mean platelet volume (MPV) is an indicator of platelet function and associated with poor clinical outcome in patients with acute coronary syndrome (ACS). We evaluated the relationship between MPV and severity of CAD in patients with ACS. A total of 395 patients with ACS were included. Severity of CAD was assessed with the Gensini and Syntax scores. High levels of MPV were associated with the Gensini and Syntax scores, number of diseased vessels (>50%), number of critical lesions (>50% and >70%), and noncritical lesions. After multivariate analysis, high levels of MPV were independent predictors of multivessel CAD together with age. In patients with ACS, high MPV levels were associated with severity of CAD. It is possible that MPV can be a helpful marker in patients with CAD for the severity of coronary atherosclerosis.

High levels of serum uric acid impair development of coronary collaterals in patients with acute coronary syndrome.

We evaluated the association of serum uric acid (SUA) level and development of coronary collateral vessels (CCVs) in patients with acute coronary syndrome (ACS). Patients (n = 224) with ACS were included in the study. Coronary collateral vessels were graded according to the Rentrop scoring system. Rentrop grade 0 was accepted as absence of CCV (group 1; n = 117) and Rentrop grade ≥1 was accepted as presence of CCV (group 2; n = 107). Rentrop 0-1 (poor CCV) were determined in 167 patients and Rentrop 2-3 (good CCV) were determined in 57 patients. Both presence of CCV (P < .001) and development of good CCV (P = .003) were significantly associated with low levels of SUA. We suggest that high levels of SUA affect the CCV development negatively in nondiabetic and nonhypertensive patients with ACS.
