Cholecystectomy in a patient with Broncho pleural fistula – An Anesthesiologist's tight rope walk
No full textPatients presenting for surgery postlobectomy with Broncho pleural fistula are prone for perioperative respiratory complications and pose a significant challenge to anesthetist. Published data to guide perioperative management of such cases especially for abdominal surgeries are scarce. We describe a 51-year-old gentleman status postlobectomy with Broncho pleural fistula posted for cholecystectomy in view of symptomatic gallstones. Laparoscopic surgery was later converted to open surgery in view of surgical difficulties. Perioperative period was uneventful and proper modes of analgesia helped in faster recovery. Proper understanding of physiological and anatomical changes and proper planning of anesthesia facilitated safe and uneventful anesthesia
TRANEXAMIC ACID ON PERIOPERATIVE BLOOD LOSS IN SPINE SURGERY: A PROSPECTIVE OBSERVATIONAL STUDY
No full textObjective: To evaluate the efficacy and safety of tranexamic acid in reducing perioperative blood loss and transfusion requirements in patients undergoing spinal surgery.
Methods: This prospective observational study was conducted at MVJ Medical College and Research Hospital from January 2022 to February 2023. Patients undergoing spinal surgery who received perioperative TXA were assessed for intraoperative blood loss, postoperative drain output, transfusion requirements, and adverse events, including thromboembolic complications.
Results: The use of TXA was associated with a significant reduction in intraoperative blood loss, postoperative drain output, and transfusion requirements. No increase in thromboembolic or other major adverse events was observed.
Conclusion: Perioperative administration of tranexamic acid is a safe and effective blood conservation strategy in spinal surgery, significantly reducing blood loss and transfusion needs without increasing thromboembolic risk

Microscopy analysis of soils at the Phoenix landing site, Mars: Classification of soil particles and description of their optical and magnetic properties
No full textThe optical microscope onboard the Phoenix spacecraft has returned color images (4 ?m pixel?1) of soils that were delivered to and held on various substrates. A preliminary taxonomy of Phoenix soil particles, based on color, size, and shape, identifies the following particle types [generic names in brackets]: (1) reddish fines, mostly unresolved, that are spectrally similar to (though slightly darker than) global airborne dust [red fines], (2) silt? to sand?sized brownish grains [brown sand], (3) silt? to sand?sized black grains [black sand], and (4) small amounts of whitish fines, possibly salts [white fines]. Most particles have a saturation magnetization in the range 0.5?2 Am2 kg?1 as inferred from their interaction with magnetic substrates. The particle size distribution has two distinct peaks below 10 ?m (fines) and in the range 20–100 ?m (grains), respectively, and is different from that of ripple soils in Gusev crater. In particular medium to large sand grains appear to be absent in Phoenix soils. Most sand grains have subrounded shape with variable texture. A fractured grain (observed on sol 112) reveals evidence of micrometer?sized crystal facets. The brown sand category displays a large diversity in color including shiny, almost colorless particles. Potential source regions for these grains may be the Tharsis volcanoes or Heimdal crater (20 km east of the landing site). The black grains are suggested to belong to a more widespread population of particles with mafic mineralogy. The absence of black/brown composite grains is consistent with different formation pathways and source regions for each grain type.Precision and Microsystems EngineeringMechanical, Maritime and Materials Engineerin
