Conclusion:Patients with ventilated nasal packs were found to have great resistance to nasal packs because of less nasal obstruction and sleep disturbance.

Application value of machine learning algorithms for gauze detection in laparoscopic pan-creatic surgery / 中华消化外科杂志

Objective:To investigate the application value of machine learning algorithms for gauze detection in laparoscopic pancreatic surgery.Methods:The retrospective and descriptive study was conducted. The 80 intact laparoscopic pancreatic surgery videos from Peking Union Medical College Hospital of Chinese Academy of Medical Sciences with timing of July 2017 to July 2020 were collected. The training set was used to train the neural network, and the test set was used to test the ability of neural network for gauze detection under different difficulties. Under the supervision of two superior doctors, videos that containing gauze were selected and classified according to recognition difficulty into three difficulty level including easy, normal and hard difficulty, and further divided based on random number method into training set with 61 videos and test set with 19 videos in a ratio of 3:1 roughly. The minimum enclosing rectangle of the gauze were marked frame by frame. All images were input to the neural network model for training after normalization and preprocessing. For every image, the output of neural network is the predicted minimum enclosing rectangle of gauze. The intersection over union >0.5 was identified as positive result. Observation indicators: (1) video annotation and classification; (2) test outcomes of neural network for test set.Count data were represented as absolute numbers or percentages.Results:(1) Video annotation and classification: a total of 26 893 frames of images form 80 videos were annotated, with 61 videos including 22 564 frames of images as the training set and 19 videos including 4 329 frames of images as the test set. Of the training set, 19 videos including 5 791 frames of images were classifed as easy difficulty, 38 videos including 15 771 frames of images were classifed as normal difficulty, 4 videos including 1 002 frames of images were classifed as hard difficulty, respectively. Of the test set, 4 videos including 1 684 frames of images were classifed as easy difficulty, 6 videos including 1 016 frames of images were classifed as normal difficulty, 9 videos including 1 629 frames of images were classifed as hard difficulty, respectively. (2) Test outcomes of neural network for test set: the overall sensitivity and accuracy of gauze detection by neural network in the test set were 78.471%(3 397/4 329) and 69.811%(3 397/4 866), respectively. The sensitivity and accuracy of gauze detection by neural network were 94.478%(1 591/1 684) and 83.168%(1 591/1 913) in easy difficulty test set. The sensitivity and accuracy of gauze detection by neural network were 80.413%(817/1 016) and 70.859%(817/1 153) in normal difficulty test set, 60.712%(989/1 629) and 54.944%(989/1 800)in hard difficulty test set. The frame rate reached more than or equally to 15 fps. The overall false negative rate and false positive rate of gauze detection by neural network in the test set were 21.529%(932/4 329) and 30.189%(1 469/4 866), respectively. The false negative was mainly due to the existence of blurred images, too small gauze exposure or blood immersion of gauze. The false positive was caused by the reflection of connective tissue or body fluids.Conclusion:The machine learning algorithms for gauze detection in laparoscopic pancreatic surgery is feasible, which could help medical staff identify gauze.

Effect of Liquid Paraffin Gauze Dressing In Burn Wounds: A Prospective Study

Introduction: Burn injury causes a considerable amount of disability, prolonged hospital stay, and burden on the public healthsector. Main requirement in burn wound management is an economical, easy to apply, readily available dressing, or method ofcoverage that will provide good pain relief, protect the wound from infection, promote healing, prevent heat and fluid loss, beelastic, non-antigenic, and adhere well to the wound while waiting for spontaneous epithelialization of superficial partial thicknessburns. The sterilized paraffin gauze dressing is non-adherent and non-allergenic and helps in speedy recovery of burn wounds.Materials and Methods: A prospective study of 90 patients with partial thickness burns who were salvageable (≤40% bodysurface area), admitted to Burn unit of Shyam Shah Medical College and associated Sanjay Gandhi Memorial Hospital,Rewa from June 1, 2017, to May 31, 2018. The autoclaved liquid paraffin gauze was applied over burn wound. Patients wereassessed on the basis of subsidence of pain, time of epithelialization if occurred after liquid paraffin gauze dressing. Patients’blood investigations were noted and the assessment of the effect of hemoglobin (anemia) and platelet counts in burn woundhealing in terms of mean epithelialization time were done.Results: Mean epithelialization time was 16 days. In 25% of cases epithelialization developed in 10–12 days. Post-burn painsubsided in 4–6 days in maximum in 54.44% cases. Mild and moderate anemia had no significant effect on wound healingtime (mean epithelialization time). Patient with less than normal platelet counts (<1.5 lakh/cumm) had more epithelializationtime and with normal platelet count had less epithelialization time. 15 patients developed complications and most commoncomplication was hyper granulation (11.11%).Conclusion: Burn wounds pose a great burden on health-care infrastructure and burn units. We can conclude that liquid paraffingauze dressing has good patient acceptability and less painful, it is easily available and relatively less expensive. In developingand resource-poor countries, most of the patients are from the rural background so these patients will need a dressing that isrelatively less expensive and easily available such as liquid paraffin gauze dressing.

Perineal Wounds - Worried?? - Stayfree

Introduction: Perineal wounds are difficult to manage as they need much frequent dressings at the hospital. Conventionaldressings are costlier and cause significant discomfort to the patient. Self-dressings using sanitary pads can be tried as analternative as they are hygienic, easily accessible, comfortable, and cost-effective.Materials and Methods: A total of 30 patients - 15 in conventional dressing and 15 in sanitary pad dressing compared in termsof compliance, comfort level, number of dressings required at hospital, cost, and return to work.Results: Patients with sanitary pad dressings were more comfortable with the method of dressing and had very less numberof dressings at the hospital. It was very much cost-effective and patients returned very early to work.Conclusion: Sanitary pad can be used as a good alternative to conventional gauze pad dressings.

Effect Of Negative Pressure Wound Therapy On The Bacterial Flora Of Wounds: A Prospective Randomized Study

20 patients were treated with negative pressure wound therapy (NPWT) and 20 patients by cotton gauze dressings. Bacterial cultures were done on 0, 4th and 8th day. The bacterial inoculates were compared between these two groups. NPWT was found to decrease pseudomonas species more than the S. aureus or E. coli species. The number of isolates of Pseudomonas decreased from day 0 (n=7) to day 8 (n=2) by NPWT. In the gauze dressing group, the number of isolates marginally increased from day 0 (n=5) to day4 (n=6) and then decreased to the baseline at day 8 (n=5). The number of isolates of E coli under gauze dressings also decreased from day 0 (n=12) to day 8 (n=6). Under NPWT however, lead an only marginal decrease in the number of isolates of E coli from day 0 (n=7) to Day 8 (n=6). Thus, NPWTis more effective to control obligate aerobic bacteria

Gauze Packing for the Massive Venous Sinus Bleeding in a Patient with Acute Subdural Hematoma of Posterior Fossa / 대한신경손상학회지

A 57-year-old male had cardiac arrest during an operation of traumatic acute subdural haematoma (ASDH) and intraparenchymal haemorrhage in the infratentorium due to a great amount of bleeding from the pre-injured venous sinus. After effective bleeding control using a gauze, the patient recovered without additional neurological sequelae. The operation of traumatic ASDH in the infratentorium always poses a risk of excessive bleeding from the injured venous sinus that could be life-threatening to the patient. This risk could be avoided with the effective first method that can immediately control the bleeding.

Design and application of fistula gauze packing drainage device / 中国中西医结合急救杂志

Gauze packing and drainage is a routine treatment for various types of fistula and sinus pressure ulcers. Because the external orifice of pressure ulcer or fistula is relatively small and the sinus deep, the conventional gauze packing has many drawbacks. Under the situation the operator is not skillful enough and no appropriate tools, it is necessary to pull the external orifice by tweezers to dilate the sinus and perform gauze packing and drainage, which brings great pain to patients, possibly leading to wound enlargement and delayed healing. At present, there is lack of auxiliary tools to improve gauze packing. Therefore, we developed and designed a gauze filler for packing and drainage of various kinds of fistula and sinus pressure ulcers, the device has the following advantages: good drainage effect, simple operation, low cost, safety and effectiveness. It not only improves the comfort of patients, reduces the number of dressing changes, reduce the number of dressing changes, shorten the hospitalization time and pay expense, but also reduces the burden of medical workers thus it is worthwhile to popularize and apply the newly designed gauze filler in clinical practice.

Is Intraoperative Use of QuikClot Combat Gauze Effective for Hemostasis after Total Knee Arthroplasty?

BACKGROUND: To assess the hemostatic effect of QuikClot Combat Gauze (QCG) compared to that of standard gauze during cruciate-retaining total knee arthroplasty (TKA). METHODS: Sixty knees underwent TKA using a pneumatic tourniquet in this prospective randomized study. After implantation of the femoral and tibial components and hardening of the bone cement, the tourniquet was deflated and QCG (group 1) or standard gauze (group 2) was packed into the joint cavity for 5 minutes for hemostasis. Perioperative bleeding volume and blood transfusion volume were compared between two groups. RESULTS: The mean intraoperative bleeding volume was 64.7 ± 12.7 mL in group 1 and 63.9 ± 9.2 mL in group 2 (p = 0.808). The mean postoperative blood drainage was 349.0 ± 170.6 mL in group 1 and 270.1 ± 136.3 mL in group 2 (p = 0.057). The average postoperative blood transfusion volume was 323.7 ± 325.9 mL in group 1 and 403.6 ± 274.8 mL in group 2 (p = 0.314). CONCLUSIONS: QCG was not significantly effective for reducing perioperative bleeding volume or the blood transfusion rate compared with standard gauze during TKA.

A 20-Year-Old Retained Surgical Gauze Mimicking a Spinal Tumor: A Case Report

A 79-year-old man visited our clinic complaining of lower back and left leg radiating pain that began 1 month prior to his presentation. He underwent surgery for lumbar disc herniation 20 years ago at another hospital. Magnetic resonance imaging revealed left-sided foraminal stenosis at L4-5. In addition, a paraspinal mass occupying the L4 spinous process and left lamina was observed. We subsequently performed an L4-5 decompression and fusion. During the operation, retained surgical gauze with granulation tissue was found. The term gossypiboma is used to define a mass lesion consisting of retained surgical gauzes and an adjacent foreign body reaction. Gossypibomas are uncommon in the paraspinal area and are mostly asymptomatic in chronic cases. Because there are no specific clinical or radiological signs, they can be confused with other tumorous conditions. Gossypibomas should be included in the differential diagnosis of paraspinal soft-tissue masses detected in patients with a history of prior spinal surgery.

Observation of the effects of three kinds of dressings at different periods for preventing nasal and facial pressure ulcers in elderly patients in the intensive care unit with continuous non -invasive ventilation / 中国基层医药

Objective To compare the effects of three kinds of dressings (foam dressings,hydrocolloid dressings,homemade gauze dressings)at different periods for preventing nasal and facial pressure ulcers in elderly patients in the intensive care unit with continuous non -invasive ventilation.Methods The study group consisted of 120 patients who were 60 years old in the intensive care unit with continuous non -invasive ventilation.They were randomly divided into A,B,C three groups with random number table.The patients in A group used foam dressings. The patients in B group used hydrocolloid dressings.The patients in C group used homemade gauze dressings.In the first week and the second week,through comparing the incidence of pressure ulcers,we compared the prevention effect of three kinds of dressings on nasal and facial pressure ulcers.Results In the first week,there was no statistical difference about the incidence of pressure ulcers among the three groups(χ2 =2.124,P =0.346).In the second week,the incidence of pressure ulcer of A group was obviously lower than B group and C group(χ2 =5.271,P =0.038).Conclusion When we nurse elderly patients in the intensive care unit with continuous non -invasive ventilation,within 7 days,we can use any one of three kinds of dressings to prevent nasal and facial pressure ulcers. But 7 days later,we should better use foam dressings.

Textiloma: Uncommon Cause of Failed Back Syndrome after Lumbar Spine Surgery.

Textiloma is the term used to describe retained foreign objects in the body which are left intentionally or accidentally during the operation. Textiloma is rare in neurosurgery. They are more frequent in thoracic and abdominal surgeries. Depending on their location, they can present with complications and symptoms or they may remain asymptomatic for many years. Textiloma and their complications are rarely reported due to medico-legal implications. In this article, we are presenting a case of spinal asymptomatic textiloma in a patient, who was operated 16 years ago, for a lumbar discectomy. On reviewing the literature, we found less than 60 cases reported until 2015.
