Fifty-four pigs ( Sus scrofa, Large White cross) from a commercial pig farm were anaesthetised over a six-year period from October 2011. The procedural stages included initial instrumentation for intra-operative monitoring, laparoscopic nephrectomy, preparation of the kidney graft, orthotopic auto-transplantation by either a laparoscopic approach or an open surgical approach, and ligation of the contralateral ureter. During the evolution and establishment of this pig model multiple refinements were introduced: (1) a heat pad was changed to a circulating warm air blanket; (2) routine administration of anticholinesterase and antimuscarinic drugs for reversal of neuromuscular blockade; (3) a technique for urethral catheterisation was developed; (4) ultrasound guidance for placement of a central venous line was learned; (5) intravenous infusions of morphine and ketamine were instituted for a more stable and balanced anaesthetic protocol; and (6) post-operative monitoring was performed by two technical staff for at least the first six hours after extubation of the trachea...

In this manuscript, we describe a significant advantage of the intraoperative near infrared spectroscopic techniques (NIRS) using in a malignant hypertensive patient during kidney transplantation. This patient underwent operation becasue of the presence of a suitable cadaveric kidney. Moreover, although the patient's hypertension was intensively treated by cardiology for a long time, it could not be controlled. Thus, despite severe hypertension, the patient was anaesthetized. Mean arterial pressures of about 70-90 mmHg, which are considered to be normal for most people, could cause cerebral hypoperfusion in such a patient...

PURPOSE: Ischaemia-reperfusion injury (IRI) is a main cause of morbidity after pulmonary resection surgery. The degradation of glycocalyx, a dynamic layer of macromolecules at the luminal surface of the endothelium, seems to participate in tissue dysfunction after IRI. Lidocaine has a proven anti-inflammatory activity in several tissues but its modulation of glycocalyx has not been investigated. This work aimed to investigate the potential involvement of glycocalyx in lung IRI in a lung auto-transplantation model and the possible effect of lidocaine in modulating IRI...

Xenon is a colourless and odourless noble gas, licensed for human use as an anaesthetic gas as well as a radiological marker. The MAC of this gas is about 63% but Xenon anaesthesia is associated with fast recovery of cognitive function and cardiovascular stability. Nevertheless, Postoperative nausea and vomiting (PONV) incidence for xenon anaesthesia is very high. Xenon has been reported to have cytoprotective effects that may have therapeutic values in both CNS protection, and in organ graft preservation. Currently, there are few studies about the effect of Xenon on ischaemia reperfusion injury of transplantable organs and insufficient clinical data upon its effect on intracranial and cerebral perfusion pressure...

To prevent renal graft thrombosis in kidney transplantation, centres use different perioperative anticoagulant strategies, based on various risk factors. In our centre, patients transplanted preemptively are considered at increased risk of renal graft thrombosis compared to patients who are dialysis-dependent at time of transplantation. Therefore these patients are given a single dose of 5000 IU unfractionated heparin intraoperatively before clamping of the vessels. We questioned whether there is a difference in haemostatic state between preemptively and non-preemptively transplanted patients and whether the distinction in intraoperative heparin administration used in our center is justified...

OBJECTIVES: We introduced an extubation strategy for emphysema patients after bilateral lung transplantation. Patients who met the extubation criteria were extubated in the operating room (OR) followed by non-invasive ventilation, and the other patients were extubated in the intensive care unit (ICU). The primary objective was to determine the extubation rate. The secondary outcomes were to determine the factors allowing for extubation in the OR and the postoperative course. METHODS: This study is a single-centre retrospective database analysis of 96 patients...

Heterotopic heart transplants were introduced in 1974. The technique allows the patient's native heart to be preserved in situ, alongside the transplanted heterotopic donor heart. We present the case of a nulliparous woman who underwent heterotopic heart transplant in infancy, and subsequent explantation of the donor heart eleven years later, when her native heart function recovered. In adulthood the patient attended pre-pregnancy counselling and was awaiting cardiac magnetic resonance imaging when she presented pregnant at 6 weeks-of-gestation...

Desensitisation with therapeutic plasma exchange (TPE) is essential for ABO-incompatible (ABO-I) liver transplants (LTs). However, excessive citrate load and coagulation disturbances after TPE have been poorly studied, in particular in cirrhotic patients with hypocapnic alkalosis, metabolic compensation and electrolyte imbalances. We retrospectively evaluated 1123 consecutive LT recipients (923 ABO-compatible [ABO-C], 200 ABO-I) from November 2008 to May 2015. TPE was generally performed a day before LT and blood sampling was performed before anaesthesia induction...

The case is presented of a post-lung transplant patient, ASA III, proposed for orchiectomy due to testicular cancer. A combination of iliohypogastric (ILH), ilioinguinal (ILI) and genitofemoral (GF) nerve block together with sedation was used as anaesthetic technique. The inguinal area received sensory innervation mainly from ILI, ILH and GF nerves. The genital branch of the GF nerve supplies innervation to skin of the anterosuperior portion of the scrotum. When performing the echo-guided block of GF nerve, it is necessary to identify the spermatic cord, and administer the local anaesthetic on the inside and periphery of the cord...

Many deceased by neurologic criteria donors are administered inhalational agents during organ recovery surgery-a process that is characterised by warm and cold ischaemia followed by warm reperfusion. In certain settings, volatile anaesthetics (VA) are known to precondition organs to protect them from subsequent ischaemia-reperfusion injury. As such, we hypothesised that exposure to VA during organ procurement would improve post-graft survival. Lifebanc (organ procurement organisation [OPO] for NE Ohio) provided the investigators with a list of death by neurologic criteria organ donors cared for at three large tertiary hospitals in Cleveland between 2006 and 2016-details about the surgical recovery phase were extracted from the organ donors' medical records...

Significant surgical advances have been made recently in corneal transplantation. Penetrating keratoplasty was the dominant method from 1905, until selective lamellar keratoplasty emerged as the preferred technique over the last 20 years. Advanced techniques such as corneal limbal stem cell transplant and keratoprosthesis are also available. The major surgical complications of corneal transplantation are extrusion of ocular content and expulsive choroidal haemorrhage. It is essential for an ophthalmic anaesthetist to have a good understanding of these new surgical procedures so as to provide optimal surgical conditions...

BACKGROUND: The role of post-reperfusion lactate clearance in assessing graft function has not yet been investigated. The aim of this study was to examine whether lactate clearance, assessed in the post-reperfusion phase, can predict poor graft function in liver transplant patients. METHODS: Seventy patients undergoing liver transplantation (LT) were enrolled. Standardised anaesthesia and intraoperative monitoring were applied. The lactate level measured immediately after venous reperfusion and 6 hours later were used to calculate lactate clearance by the following formula: [(reperfusion lactate - 6h post-reperfusion lactate)/reperfusion lactate] ×100...

OBJECTIVES: Volatile anaesthetics can provide significant protection against reperfusion injury in various experimental settings. The aim of this study was to assess the potential of sevoflurane treatment, the most commonly used volatile anaesthetic in modern anaesthesia, in rat lungs donated after circulatory death and reconditioned in an ex vivo lung perfusion (EVLP) system. METHODS: Fifteen rats were sacrificed and divided into 3 groups. In the control and sevoflurane groups, the heart-lung blocks were exposed to 1 h of warm ischaemia and 2 h of cold ischaemia and were mounted on an EVLP circuit for 3 h, in the absence or in the presence of 2% sevoflurane...

OBJECTIVES: Currently, most of the artificial airway organs still require scaffolds; however, such scaffolds exhibit several limitations. Alternatively, the use of an autologous artificial trachea without foreign materials and immunosuppressants may solve these issues and constitute a preferred tool. The rationale of this study was to develop a new scaffold-free approach for an artificial trachea using bio-3D printing technology. Here, we assessed the circumferential tracheal replacement using scaffold-free trachea-like grafts generated from isolated cells in an inbred animal model...

The annual heart transplant rate is gradually increasing worldwide. A proportion of this patient population present for an elective or emergency surgery which may or may not be related to the transplanted heart. A MEDLINE search for heart transplant, anaesthesia, adult, paediatric and surgery was conducted to review anaesthetic management for heart transplant recipients. Anaesthesia and perioperative management are different in these cases. A thorough understanding of the physiology of denervated heart, post-transplant morbidities and pharmacology of immunosuppressants is essential for best perioperative management and improved post-operative outcome...

BACKGROUND: Effect of anaesthesia and surgery on cell-free DNA (cfDNA) is not known. Given that surgical stress augments inflammation and injury, we hypothesized that levels of cfDNA will fluctuate during perioperative period. Therefore, in this study serial perioperative cfDNA concentration was measured in donors and recipients undergoing living donor liver transplantation (LDLT). METHODS: Baseline, post-induction, intraoperative and post-operative plasma cfDNA levels were evaluated in 21 donors and recipients each, by Sytox green method...
