Article Synopsis
- Laparoscopic hepatectomy offers benefits like reduced hospital stays, lower blood loss, and fewer complications, but can lead to life-threatening carbon dioxide gas embolism.
- A 70-year-old male experienced this complication during surgery due to a previous catheter ablation that created an atrial septal defect (ASD), which was identified using transesophageal echocardiography.
- The surgical approach was changed to open surgery, and the patient recovered without neurological issues, highlighting the need for monitoring in patients with similar medical histories during laparoscopic procedures.
Article Synopsis
- This study evaluated the challenges faced by novice trainee anesthesiologists in performing neuraxial anesthesia for cesarean sections compared to experienced anesthesiologists.
- Novice anesthesiologists took significantly longer to administer neuraxial anesthesia (24.9 min) than their senior counterparts (18.2 min), and maternal BMI was found to further impact the time taken, particularly for novices.
- Despite the longer time required, the experience level did not significantly affect maternal hemodynamics or newborn outcomes, suggesting that novices can perform safely under supervision.
Purpose: This study retrospectively assessed blood loss during cesarean deliveries for twin and singleton pregnancies using two distinct methods, quantitative estimation measured during cesarean sections and hematocrit-based calculated estimation.
Methods: We included scheduled cesarean deliveries for twin or singleton pregnancies at ≥ 34 weeks of gestation. Quantitative blood loss was recorded based on the blood volume in the graduated collector bottle and by weighing the blood-soaked textiles during cesarean sections.
Article Synopsis
- - This study aimed to assess the effectiveness of haptic feedback during telesurgery to enhance safety in robotic surgery practices.
- - Experiments involved a surgeon operating from two separate locations, and while no significant impact on task accuracy was found, the remote operations resulted in longer completion times and lower usability ratings.
- - Haptic feedback allowed surgeons to use lighter grasping forces, particularly benefiting experienced surgeons, highlighting its potential as a crucial tool for safe and effective telerobotic surgery.
Article Synopsis
- This study introduces a double-surgeon cockpit system for telesurgery, marking a significant step in developing a clinically applicable telesurgical technique.
- It involved non-specialized surgeons performing surgeries on pigs with remote assistance and evaluated the effect of internet security measures on communication during procedures.
- Results showed promising outcomes, with non-specialized surgeons performing safely and effectively, indicating the feasibility of this system as a foundation for future clinical telesurgery.
