Perioperative Materno-Fetal Morbimortality Related to the Caesarean in the Hospital Setting in Mali

Introduction: During childbirth by Caesarean, several types of anesthesia can be used. The Caesarean, the most practiced surgical delivery technique in obstetrics, has a risk for complications for both the pregnant women and newborns. Objective: To evaluate the importance of the complications due to Caesarean in the Teaching hospital Gabriel Toure. Patient and Methods: We conducted a cross sectional survey in the departments of intensive care unit and gyneco-obstetric from January to August 2017 in the University hospital Gabriel Touré of Bamako. Our study population was pregnant women who gave birth to children by Caesarean. We included all cases of preventive and emergent Caesarean under loco-regional or general anesthesia. Data were compiled from the obstetrical files of the patients, the anesthetic consultation registry and the databasis of the department of gyneco-obstetric. The test of khi2 of Pearson was used for the comparison of our results with a value of p < 0.05 considered as statistically significant. The consent of the patients or parents was gotten. The survey didn’t include a potentially dangerous act. Results: During the study period, 1875 childbirths have been recorded of which 633 were by Caesarean (33.7%). We collected and analyzed 524 files of Caesarean. The mortality rate was 1.5% in pregnant women and 15% in newborns. The average age was 26.6 ± 6.9 ans. Pregnant women were referrals in 59.4% of the cases. The most frequent motive of referrals was high blood pressure and pregnancy in 66.6%. The Caesarean was indicated in most of the cases on previously operated uterus in 22% and eclampsia was present in 14%. The maternal mortality had occurred in a context of hemorrhage in 50% of the cases. The factors of maternal morbi-mortality were the mode of admission, iterative Caesarean, t surgeon, context of the Caesarean, realization of the anesthetic consultation and the technic of anesthesia (p = 0.05). The factors of fetal mortality were the realization of endo-tracheal intubation, technic of anesthesia, realization of the anesthesia consultation, context of the Caesarean, iterative Caesarean and the mode of admission (p ≤ 0.05). Conclusion: The caesarean is associated with a high risk of maternal complications and a very important fetal mortality. The anesthesia consultation in the follow-up of pregnancy would reduce this high mortality.

Effectiveness of an Underbody Forced Warm-Air Blanket during Coronary Artery Bypass Surgery in the Prevention of Postoperative Hypothermia: A Prospective Controlled Randomized Clinical Trial

Introduction: Perioperative hypothermia in cardiac surgery is associated with adverse outcome. The aim of this investigation was to study whether an underbody forced-air warming blanket during coronary artery bypass graft surgery with normothermic cardiopulmonary bypass can prevent postoperative hypothermia. Methods: After Medical Ethics Committee approval, 60 low-risk cardiac surgery patients at random were assigned into a group that received standard thermal care management (control group n = 30) and a group that received the underbody forced-air warming system plus the standard thermal care (intervention group n = 30). Results: The temperature after-drop from the end of cardiopulmonary bypass to arrival in the ICU was less in the intervention group versus control group (0.4°C ± 0.3°C vs 0.6°C ± 0.4°C;P = 0.027). Out of the intervention group, 27 patients arrived in the ICU with a bladder temperature ? 36°C (90%) as compared to 14 patients (46.7%) from the control group (P < 0.001). The peripheral temperature was significantly higher in the intervention group as compared to the control group (P < 0.001). Conclusions: A full underbody forced-air warming blanket prevents postoperative hypothermia in normothermic coronary artery bypass graft surgery patients.

The Popularization and Application of Cold Storage Red Blood Cells or Whole Blood at -80 ℃ of the Rh(D) Negative Patients in Surgical Operation

Summary: The efficiency of cold storage red blood cells (CSRBC) or whole blood at -80 ℃ used in 27 Rh(D) negative patients during surgical operation was reported. The Rh(D) negative patients received the transfusion of CSRBC or whole blood stored at -80 ℃ for 180 to 360 days. The changes in the indexes, such as blood TB, DB, K +, Na +, BUN, Cr, urine protein (URPO), UOB, Hb, HCT, serum total protein, relative to hemolytic reaction and blood volume before and after transfusion were observed. The results showed that after transfusion of CSRBC or whole blood 27 cases were negative for urine protein and UOB, and the levels of BUN and Cr were normal (P>0.05). Blood TB, DB, Hb, and HCT were increased, while pH, blood K + and blood Na + was normal with the difference being not significant before and after operation (P>0.05). Plasma protein was decreased, but there was no significant difference before and after operation (P>0.05). It was suggested that CSRBC or whole blood at -80 ℃ could be safely infused to the Rh(D) negative patients without side effects during the surgical operation.

<i>H</i>(.,.)<i>- φ - η -</i>Accretive Operators and Generalized Variational-Like Inclusions

In this paper, we generalize H(.,.) accretive operator introduced by Zou and Huang [1] and we call it H(.,.)- φ - η - accretive operator. We define the resolvent operator associated with H(.,.)- φ - η - accretive operator and prove its Lipschitz continuity. By using these concepts an iterative algorithm is suggested to solve a generalized variational-like inclusion problem. Some examples are given to justify the definition of H(.,.)- φ - η - accretive operator.

Semi-Commutative Differential Operators Associated with the Dirac Opetator and Darboux Transformation

In the present paper, the semi-commutative differential oparators associated with the 1-dimensional Dirac operator are constructed. Using this results, the hierarchy of the mKdV (-) polynomials are expressed in terms of the KdV polynomials. These formulas give a new interpretation of the classical Darboux transformation and the Miura transformation. Moreover, the recursion operator associated with the hierarchy of the mKdV (-) polynomials is constructed by the algebraic method.

Loosely coordinating diluted highly concentrated electrolyte toward -60℃ Li metal batteries

Lithium metal batteries(LMBs) promise energy density over 400 Wh kg^(-1).However,they suffer severe electrochemical performance deterioration at sub-zero temperatures.Such failure behavior highly correlates to inferior lithium metal anode(LMA) compatibility and sluggish Li^(+) desolvation.Here,we demonstrate that cyclopentylmethyl ether(CPME) based diluted high-concentration electrolyte(DHCE)enables-60℃ LMBs operation.By leveraging the loose coordination between Li^(+) and CPME,such developed electrolyte boosts the formation of ion clusters to derive anion-dominant interfacial chemistry for enhancing LMA compatibility and greatly accelerates Li^(+) desolvation kinetics.The resulting electrolyte demonstrates high Coulombic efficiencies(CE),providing over 99.5%,99.1%,98.5% and 95% at 25,-20,-40,and-60℃respectively.The assembled Li-S battery exhibits remarkable cyclic stability in-20,and-40℃ at 0.2 C charging and 0.5 C discharging.Even at-60℃,Li-S cell with this designed electrolyte retains> 70% of the initial capacity over 170 cycles.Besides,lithium metal coin cell and pouch cell with10 mg cm^(-2) high S cathode loading exhibit cycling stability at-20℃.This work offers an opportunity for rational designing electrolytes toward low temperature LMBs.

Comparative study of CEA and CA19-9 in esophageal,gastric and colon cancers individually and in combination(ROC curve analysis)

Objective： To determine the clinical serum levels of carcinoembryonic antigen （CEA） and carbohydrate antigen 19-9 （CA19-9）, individually and in combination, for the diagnosis of 50 healthy subjects and 150 cases of esophageal, gastric, and colon cancers. Methods： The sensitivities of the two markers were compared individually and in combination, with specificity set at 100%. Receiver operating characteristic （ROC） curves were plotted. Results： Serum CEA levels were significantly higher in cancer patients than in the control group. The sensitivity of CEA was determined： in esophageal cancer, sensitivity=28%, negative predictive value （NPV）=61.72%, and AUC=0.742 （SE=0.05）, with a significance level of P〈0.0001; in gastric cancer, sensitivity=30%, NPV=58.82%, and AUC=0.734 （SE=0.0S）, with a significance level of P〈0.0001; in colon cancer, sensitivity=74%, NPV=79.36%, and AUC=0.856 （SE=0.04）, with a significance level of P〈0.0001. The sensitivity of CA19-9 was also evaluated： in esophageal cancer, sensitivity=18%, NPV=54.94%, and AUC=0.573 （SE=0.05）, with a significance level of P=0.2054. In gastric cancer, sensitivity=42%, NPV=63.29%, and AUC=0.679 （SE=0.05）, with a significance level of P〈0.0011. In colon cancer, sensitivity=26%, NPV=57.47%, and AUC=0.S80 （SE=0.05）, with a significance level ofP=0.1670. The following were the sensitivities of CEA/CA19-9 combined： in esophageal cancer, sensitivity=42%, NPV=63.29%, SE=0.078 （95% CI： 0.0159-0.322）; gastric cancer, sensitivity=S8%, NPV=70.42%, SE=0.072 （9$% CI： -0.0866-0.198）; and colon cancer, sensitivity=72%, NPV=78.12%, SE=0.070 （9S% CI： 0.137-0.415）. Conclusion： CEA exhibited the highest sensitivity for colon cancer, and CA19-9 exhibited the highest sensitivity for gastric cancer. Combined analysis indicated an increase in diagnostic sensitivity in esophageal and gastric cancer compared with that in colon cancer.

Clinical value of serum CA19-9 levels in evaluating resectability of pancreatic carcinoma

AIM:To evaluate the clinical value of serum CA19-9 levels in predicting the respectability of pancreatic carcinoma according to receiver operating characteristic(ROC) curve analysis. METHODS:Serum CA19-9 levels were measured in 104 patients with pancreatic cancer which were possible to be resected according to the imaging. ROC curve was plotted for the CA19-9 levels. The point closest to the upper left-hand corner of the graph were chosen as the cut-off point. The sensitivity,specificity,positive and negative predictive values of CA19-9 at this cut-off point were calculated. RESULTS:Resectable pancreatic cancer was detected in 58(55.77%) patients and unresectable pancreatic cancer was detected in 46(44.23%) patients. The area under the ROC curve was 0.918 and 95% CI was 0.843-0.992. The CA19-9 level was 353.15 U/mL,and the sensitivity and specificity of CA19-9 at this cut-off point were 93.1% and 78.3%,respectively. The positive and negative predictive value was 84.38% and 90%,respectively. CONCLUSION:Preoperative serum CA19-9 level is a useful marker for further evaluating the resectability of pancreatic cancer. Obviously increased serum levels of CA19-9(> 353.15 U/mL) can be regarded as an ancillary parameter for unresectable pancreatic cancer.

Low noise,continuous-wave single-frequency 1.5-μm laser generated by a singly resonant optical parametric oscillator

We report a low noise continuous-wave （CW） single-frequency 1.5-μm laser source obtained by a singly resonant optical parametric oscillator （SRO） based on periodically poled lithium niobate （PPLN）. The SRO was pumped by a CW single-frequency Nd：YVO4 laser at 1.06μm. The 1.02 W of CW single-frequency signal laser at 1.5 μm was obtained at pump power of 6 W. At the output power of around 0.75 W, the power stability was better than ±l.5% and no mode-hopping was observed in 30 min and frequency stability was better than 8.5 MHz in 1 min. The signal wavelength could be tuned from 1.57 to 1.59 μm by varying the PPLN temperature. The 1.5-μm laser exhibits low noise characteristics, the intensity noise of the laser reaches the shot noise limit （SNL） at an analysis frequency of 4 MHz and the phase noise is less than 1 dB above the SNL at analysis frequencies above 10 MHz.

A Retrospective Comparison of Interscalene Continuous Catheter Verse Single-Injection with Liposomal Bupivacaine in Total Shoulder Arthroplasty

Background: One common method of pain control for total shoulder arthroplasty is long-duration delivery of local anesthetic via interscalene brachial plexus block (ISB) with a continuous catheter. Alternatively, liposomal bupivacaine has also been administered as an ISB as a means to prolong the analgesic effect. This study was completed to measure the non-inferiority of single-injection ISB with liposomal bupivacaine compared with ISB continuous catheter for total shoulder arthroplasty. Methods: We performed a retrospective chart review of patients who underwent total shoulder arthroplasty using either an ISB continuous catheter or a single injection ISB with liposomal bupivacaine for post operative analgesia. The primary goal of this study was to determine if single-injection with liposomal bupivacaine conferred non-inferior pain scores compared to the continuous catheter. Secondary outcomes evaluated oxygen saturation as a measure of hemidiaphragmatic paresis, post operative opioid requirements, and difference in cost. Results: We identified 333 patients for the study: 126 received continuous catheter and 207 received single-injection with liposomal bupivacaine. The median length of stay was 1 day. Pain scores for those treated with single-injection with liposomal bupivacaine were non-inferior to pain scores of those treated with the continuous catheter on post-op days 0, 1 and 2. Pain scores were lower for single-injection with liposomal bupivacaine patients on days 3 and 4, however they did not reach statistical significance. There was no significant difference in oxygen saturation between the two groups. Both groups had similar daily morphine milligram equivalent requirements. Liposomal bupivacaine ISB was also found to be less expensive. Conclusion: Single-injection ISB with liposomal bupivacaine provides non-inferior analgesia at a reduced cost compared with continuous catheter ISB for total shoulder arthroplasty.
