Znieczulenie do cięcia cesarskiego u rodzących z łożyskiem przodującym z/bez łożyska wrośniętego – badanie retrospektywne
Objectives: The aim of this retrospective study was to review placenta previa cases and determine the prognostic factors effective on morbidity and mortality and to evaluate the strategy of anesthetic management. Material and methods: 65 women with placenta previa scheduled for elective or emergency cesarean sections from 2004 to 2009 were examined. Patient demographic data, surgery and obstetric characteristics, anesthetic techniques, blood transfusions, the values of hemoglobin and complications were recorded. Results: Mostly, general anesthesia was preferred in the parturients with placenta previa (86.2%, 56/65). 9 patients (13.8%), 2 of whom were converted to general anesthesia due to bleeding and prolonged surgery, received regional anesthesia. 37 of 65 women (56.9%) with placenta previa had had cesarean sections previously. More than half of these patients (21/37, 56.7%) had abnormally invasive placentation and 16 of 21 cases underwent cesarean hysterectomy. The incidence of complications in women with previous cesarean section with abnormally invasive placentation was higher than in the other women (pCel pracy: Celem tego retrospektywnego badania była analiza przypadków łożyska przodującego pod kątem oceny czynników prognostycznych wpływających na zachorowalność i śmiertelność oraz ocena postępowania anestezjologicznego. Materiał: Przeanalizowano 65 przypadków kobiet z łożyskiem przodującym zakwalifikowanych do elektywnego lub pilnego cięcia cesarskiego w latach 2004-2009.Zebrano następujące dane: demograficzne, wywiad operacyjny i położniczy, techniki anestezjologiczne, transfuzje krwi, poziomy hemoglobiny i powikłania. Wyniki: Preferowaną metodą znieczulenia u rodzących z łożyskiem przodującym było znieczulenie ogólne (86,2%; 56/65). Przewodowe znieczulenie otrzymało 9 pacjentek (13,8%) ale u 2 z nich trzeba było przejść na znieczulenie ogólne z uwagi na krwawienie i przedłużony czas operacji. 37 z 65 kobiet (56,9%) z łożyskiem przodującym miało cięcie cesarskie w poprzedniej ciąży. Więcej niż połowa tych pacjentek (21/37, 56,7%) miała nieprawidłowo utworzone łożysko a 16 z 21 przeszło histerektomię położniczą. Częstość powikłań u kobiet po cięciu cesarskim w wywiadzie i z nieprawidłowo utworzonym łożyskiem w analizowanym materiale była wyższa niż u innych pacjentek (
The effects of CO2 pneumoperitoneum at different temperature and humidity on hemodynamic and respiratory parameters and postoperative pain in gynecological laparoscopic surgery: A prospective randomized controlled study
Background: It is recommended to heat and humidity CO2 in laparoscopic surgery to prevent postoperative pain and hypothermia but information about its effects on hemodynamic and respiratory parameters is limited. We aimed to investigate the effects of standard and heated-humidified CO2 on hemodynamic and respiratory parameters, body temperature and pain in healthy patients. Methods: One hundred patients who underwent total laparoscopic hysterectomy for benign pathology were divided into two groups: Group CD (cold-dry) patients were administered standard CO2, while Group HH (heated-humidified) patients were administered 95% humidified insufflation at 37 degrees C. Hemodynamic and respiratory parameters, body temperature, pain score and blood count parameters were recorded. Results: A total of 96 patients were included in the study, taken from the 100 patients. Group HH (n:47) had only higher systolic blood pressure at 75, mean blood pressure at 50 and 55 and a lower heart rate between 15 and 45 min (p:0.049, 0.037, 0.013 respectively). Pain score, morphine consumption, end-tidal CO2 and arterial blood gas values were not different between the groups, with only body temperature from 40 min and minimum value being significantly higher (at a difference of 0.86-1.04 degrees C) in Group HH. Postoperative leukocyte, neutrophil and NLR (neutrophil-leukocyte ratio) were found to be higher in this group (p 0.05). Conclusion: It has been found that both standard and heated-humidified CO2 do not constitute a problem in terms of hemodynamic and respiratory parameters in healthy patients. The heated-humidified CO2 group had only a higher core body temperature and inflammatory response. (C) 2021 Asian Surgical Association and Taiwan Robotic Surgery Association.

The effects of uterine size with or without abdominal obesity on spinal block level and vasopressor requirement in elective cesarean section: a prospective observational study
WOS: 000458367000008PubMed ID: 30761854Background/aim: Hypotension is a serious complication caused by spinal anesthesia that places both the mother and fetus at increased risk. We aimed to investigate the effects of uterine size with or without abdominal obesity on sensory block level of pregnant women receiving spinal anesthesia. Materials and methods: This study included 125 term parturients who underwent cesarean section. Motor and sensory block characteristics, the distance between the symphysis pubis and the fundus (SIT), the distance between the symphysis pubis and the xiphoid (SPX), newborn and placental weights, adverse effects, and doses of ephedrine were recorded. Results: Sensory block level and ephedrine dose were significantly correlated with the SPX and the combined newborn and placenta weights (P < 0.05). The incidence of hypotension was related to the SPX and the combined newborn and placenta weight (P < 0.05). There was no correlation between the SPF and sensory block level or ephedrine dose. The sensory block level was higher for patients who had greater SPX values and higher combined newborn and placenta weights. The incidence of hypotension and the ephedrine dose were also higher in these subjects. Conclusion: SPX values and combined newborn and placenta weights are more predictive of sensory block level than SPF values in parturients receiving spinal anesthesia
Effect of Coagulation Status and Co-Morbidity on Flap Success and Complications in Patients with Reconstructed Free Flap
WOS: 000463175700003PubMed ID: 31080950Objective: Free flap surgeries constitute the basis of reconstruction surgery in patients with major defects. Prediction of complications that cause flap loss in such patients is important in terms of reducing the length of hospital stay and expenses. We aimed to retrospectively investigate the effect of co-morbidities and the coagulation status on flap loss and complications in patients with reconstructed free flap. Methods: Demographic data, smoking, alcohol habits, co-morbidities, coagulation tests and thromboelastogram results from preoperative, intraoperative and postoperative anaesthesia and surgical records of patients undergoing free flap surgeries between January 2015 and June 2017 were retrospectively screened. Results: Flap success rate was found to be 96.1% in total 77 patients with free flap. Coagulation related complication rate, such as thrombosis, haematoma and partial necrosis, were 22.1%. There was a significant relationship between age, chronic obstructive pulmonary disease and hypercholesterolaemia and flap loss (p=0.006, p=0.025 ve p=0.025, respectively). Flap complications were more frequent in patients with chronic obstructive pulmonary disease and hypertension. Laboratory test results revealed no statistical correlation between flap complications and flap loss with preoperative and postoperative TEG. Conclusion: Advanced age, co-morbidities such as hypertension and chronic obstructive pulmonary disease are associated with complications and flap loss in free flap surgery However, there were no clinically significant association of complications and flap loss with laboratory tests showing coagulation. We believe that standardised protocols should he established in terms of preparation, intraoperative management and postoperative follow-ups because the time between taking the coagulation tests and postoperative anticoagulant administration should be standardised in such surgeries
Single-Site Robotic Total Hysterectomy: Standardization of Technique and Surgical Outcomes
WOS: 000340686800032PubMed ID: 24530696Study Objectives: To evaluate the safety and feasibility of robotic single-site total hysterectomy and to compare the outcomes of newly implemented robotic single-site bipolar and external vessel-sealing device. Design: Retrospective study (Canadian Task Force classification II-1). Setting: University hospital. Patients: Twenty-four patients with benign indications for hysterectomy. Interventions: All patients underwent robotic-assisted single-incision transumbilical total hysterectomy using the novel da Vinci Single-Site Platform. Vaginal cuff closures were performed intracorporeally using the same technique in all cases. Measurements and Main Results: The median age of the patients was 49.5 years (range, 40-61), and body mass index was 28.5 (range, 21-34). Blood loss was 22.5 mL (range, 7-120 mL). Docking time was 5.5 minutes (range, 3-10 minutes), console time was 74.5 minutes (range, 60-160 minutes), vaginal cuff closure time was 25 minutes (range, 16-41 minutes), and total operative time was 98.5 minutes (range, 71-183 minutes). When 2 groups were created according to the energy devices used during the procedures, console time in the newly implemented bipolar group was shorter than in the external sealing device group (69.5 minutes vs 77 minutes; p = .03); however, no differences were found for uterus removal time (50.5 minutes vs 53.5 minutes; p = .13). Differences were observed in vaginal cuff closure time (18.5 minutes vs 23 minutes; p = .01). Conclusion: Robotic single-site total hysterectomy using a newly implemented bipolar grasping instrument and even with intracorporeal cuff closure is a safe and feasible procedure in appropriately selected patients.

Blood Count Parameters can be Useful in Predicting Vascular Events in Microvascular Surgery: Results of a Preliminary Study
Background: Vascular events are a major cause of flap failure and identifying patients who are at risk is of paramount importance. In the past, many studies have been conducted to investigate the effect of blood count parameters for ischemic events such as peripheral vascular diseases. Aims: This study aimed to evaluate whether blood count parameters can have predictive value for vascular events in microvascular flap surgery. Methods: Elective cases with free flap microsurgery performed in a single center were reviewed from 2015 to 2019. Demographic data, comorbidities, flap types, perioperative complications, and preoperative blood count parameters from the hospital records were screened. Results: A total of 147 patients were included in the study, taken from the 163 patients undergoing free tissue transfer. The rate of thrombosis and partial necrosis was 8.8%, was 8.2%, respectively, and the total flap loss due to these complications was 5.4%. Only patient age, gender, and length of hospital stay were correlated with flap loss. According to the preoperative blood count results, there were significant differences between vascular events and leucocyte, and neutrophil counts. Conclusion: The findings of this preliminary study suggest that these parameters may be used in predicting vascular events in flap surgery
The Effects of Different Pressure Pneumoperitoneum Models Created By Standard or Heated-Humidified CO2 Insufflation on Ovary and Peritoneum: an Experimental Study in Rats
There is still controversy over whether structural and morphological changes can be observed in tissues depending on the carbon dioxide (CO2) nature or the applied intra-abdominal pressures (IAP). This study aimed to investigate the effects of different pressure or CO2 nature used for pneumoperitoneum in gynecological laparoscopic surgery on inflammation, DNA damage, oxidative stress, and histopathological changes in ovarian and peritoneal tissue. For this purpose, forty female rats were randomly divided into 6 groups and different pneumoperitoneum models were created in these groups. Rats in group other than control and sham groups received standard (CD) or heated-humidified CO2 (HH) insulations at low (4 mmHg) or high pressure (8 mmHg). The ovary and peritoneum sections were evaluated microscopically for apoptotic index (API) and API scoring was calculated. Tissue and plasma interleukin-6 (IL-6), tumor necrotizing factor-alpha (TNF-alpha), anti-Mullerian hormone (AMH) and 8-hydroxydeoxyguanosine (8-OHdG) levels were analyzed with enzyme-linked immunosorbent assay (ELISA). The most severe changes occurred in the 8CD group microscopically, while the least severe changes occurred in the 4HH group. All histopathological parameters except for ovarian apoptotic index and peritoneal PCNA at low pressure were higher in the CD group. TNF-alpha and 8-OHdG levels were higher in the CD group at both low and high pressures. Standard CO2 caused more prominent histopathological changes at high pressures and systemic inflammation in both pressure groups. The least change between the experimental study groups in terms of histopathological and biochemical was observed in the low-pressure heated-humidified group.This study was supported by the Ege University Scientific Research Projects Coordination Unit (grant number: TGA-2019-20808 (to Ilkben Gunusen)).Ege University Scientific Research Projects Coordination Unit [TGA-2019-20808
