Ten-min prewarming for breast surgery

Purpose : We evaluated the effect of 10-min prewarming on core temperature maintenance during general anesthesia. Patients : We randomized 40 women scheduled for breast cancer surgery into 10-min Prewarming and Control groups. In the Prewarming group, a forced-air warming system was used to warm the patients at 43℃ for 10 min immediately before general anesthesia induction. In the Control group, the patients were kept warm using cotton thermal blankets for 10 min. We measured tympanic temperature every 15 min from anesthesia induction for 90 min. Findings : Since two patients deviated from the protocol, we used the data of 38 patients (Prewarming [n = 18] and Control [n = 20]). There was a significant between-group difference in changes in core temperature (P = 0.03), including a significant difference in core temperature decrease during the first 60 min from anesthesia induction (Prewarming : −0.3 [0.3] ℃ vs. Control : −0.6 [0.2] ℃, P = 0.02). In addition, the duration of normal core temperature maintenance was significantly longer in the Prewarming group (66 [34] min vs. 39 [32] min, P = 0.01). Conclusions : Ten-min prewarming decreases core temperature loss and contribute to maintaining normal core temperature during breast surgery

Fogarty catheter for OLV of a neonate

Here, we report two cases involving a neonate and child in which a slip joint section was used to thread a Fogarty catheter into the endotracheal tube for one-lung ventilation (OLV). Both the neonate and infant required OLV, and were placed under general anesthesia. A Fogarty catheter was used for OLV. The Fogarty catheter was passed into the intraluminal side of the endotracheal tube through a slip joint section. OLV was maintained successfully without severe air leakage or Fogarty catheter displacement. The neonate had been intubated pre-operatively with a 3.5-mm inner diameter endotracheal tube, and we used that tube. These cases indicate that the technique can be applied to pre-operatively intubated patients and does not require surgeons to exchange endotracheal tubes. Use of the slip joint section technique facilitates Fogarty catheter fixation without additional dead space

Efficacy of Combination Treatment with Tadalafil and Mirabegron in Patients with Benign Prostatic Hyperplasia Who Presented with Persistent Storage Symptoms After Tadalafil Monotreatment: A Prospective, Multicenter, Open-Labeled Study

Background: The aim of this study is to evaluate the efficacy and safety of tadalafil, a phosphodiesterase type 5 inhibitor, plus mirabegron, a β3-adrenoreceptor agonist, in patients with benign prostatic hyperplasia who presented with persistent storage symptoms after tadalafil monotreatment. Methods: The registration of this study started in August 2016 and ended in July 2019. The inclusion criteria included patients aged ? 50 years who were diagnosed with benign prostatic hyperplasia and who presented with overactive bladder symptoms. Patients were treated with oral tadalafil 5 mg once daily for 4 weeks. Then, its efficacy was evaluated. Patients who responded to the treatment received oral tadalafil 5 mg once daily for 4 more weeks (monotreatment group). Meanwhile, those who did not respond received oral tadalafil 5 mg and mirabegron 50 mg, which is an add-on treatment, once daily for 4 more weeks (combination therapy group). Results: After 8 weeks, the monotreatment group (n = 19) and the combination group (n = 56) had significantly better total Overactive Bladder Symptom Score and International Prostate Symptom Score and International Prostate Symptom Score voiding and storage subscale scores. Moreover, the two groups experienced significant improvements in the total Overactive Bladder Questionnaire and Nocturia Quality of Life Questionnaire scores, and Nocturia Quality of Life Questionnaire Bother/Concern subscale score after 8 weeks. However, there were no cases of urinary retention or serious adverse events. Conclusion: Combination treatment with tadalafil and mirabegron is effective and safe for patients with benign prostatic hyperplasia who presented with persistent storage symptoms after tadalafil monotreatment. Hence, tadalafil plus mirabegron is a promising therapeutic option, and it can improve overactive bladder related-quality of life

A Comparison Between Laparoscopic and Robot-Assisted Laparoscopic Pyeloplasty in Patients with Ureteropelvic Junction Obstruction

Background: The aim of this study is to compare the results of laparoscopic pyeloplasty and robot-assisted laparoscopic pyeloplasty in patients with ureteropelvic junction obstruction. Methods: Between March 2008 and May 2019, the patients who underwent retroperitoneal laparoscopic or robotic-assisted laparoscopic pyeloplasty in our institution were retrospectively reviewed. Results: Thirteen patients underwent laparoscopically, and 12 patients underwent robotic surgery. The significant difference was found in median operative time between laparoscopic group (296 minutes) and robotic group (199 minutes) (P = 0.001). The median time for drain removal in laparoscopic group was longer than robotic group (3 vs. 2 days, respectively, P = 0.029). Conclusion: Laparoscopic and robot-assisted laparoscopic pyeloplasty is safe and excellent success rates in patients with ureteropelvic junction obstruction. However, our experience study suggested that robotic surgery improves a total operative time, decreases drain removal time and less intraoperative blood loss than laparoscopic approach

The Influence of Prior Abdominal Surgery on Robot-Assisted Partial Nephrectomy

[Background] We evaluated the influence of prior abdominal surgery on perioperative outcomes in patients who underwent robot-assisted partial nephrectomy in initial Japanese series. [Methods] We reviewed patients with small renal tumors who underwent robot-assisted partial nephrectomy from October 2011 to September 2020 at our institution. Patients with prior abdominal surgery were compared with those without prior surgery based on perioperative outcomes. The chi-square test and Mann–Whitney U test were used for statistical analyses of variables. [Results] Of 156 patients who underwent robot-assisted partial nephrectomy, 90 (58%) had no prior abdominal surgery, whereas 66 patients (42%) underwent prior abdominal surgery. No significant differences in perioperative outcomes were observed between with and without prior abdominal surgery groups. In transperitoneal approach robot-assisted partial nephrectomy, 31 patients (80.4%) had prior abdominal surgery. Trocar insertion time in the with prior abdominal surgery group took longer than the without prior abdominal surgery group (32 vs. 28.5 min, P = 0.031). No significant difference was observed in the conversion rate between the two groups (P = 0.556). [Conclusion] Robot-assisted partial nephrectomy appears to be a safe approach for patients with prior abdominal surgery. In transperitoneal approach robot-assisted partial nephrectomy with prior abdominal surgery, trocar insertion time was longer, but no significant differences were found in other outcomes. Transperitoneal approach robot-assisted partial nephrectomy is thus considered a safe procedure for patients with prior abdominal surgery

Experience of Cadaver Donor Nephrectomy with Cadaver Surgical Training

As cadaver donor nephrectomy in kidney transplantation is performed in only a limited number of cases, few physicians are skilled in the surgical technique. We performed two cadaver donor nephrectomy sessions during cadaver surgical training. The first session was performed by a lecturer who was skilled in the technique, with physicians and nurses participating in order to learn the methodology. The second session was conducted only for physicians. The procedures undertaken were as follows: cannulation of the femoral artery and vein, skin incision and bowel ligation, cross-clamping of the aorta, diaphragmatic incision and inferior vena cava incision, dissection of the aorta and inferior vena cava, and nephrectomy. Although there were some differences from that normally observed in actual patient surgery, such as no bleeding and formalin fixation, some of the procedures were very useful in helping to better understand cadaver donor nephrectomy

Behavioral Partitioning with Exploiting Function-Level Parallelism

Abstract-This paper proposes a method to efficiently generate hardware from a large behavioral description by behavioral synthesis. For a program with functions which are executable in parallel, this proposed method determines an optimal behavioral partitioning which fully exploits the function-level parallelism with simultaneously minimizing the area in the datapath and control path. This partitioning problem is formulated as an integer programming problem. Experimental results demonstrate the effectiveness of our proposed method
