Objectives: Our aim was to investigate the negative effects of transferring brain-dead donors to the intensive care unit on the ratio of PaO₂ to inspired oxygen fraction and the benefits of recruitment maneuvers on its reversal.

Materials And Methods: In this randomized trial, we assigned 30 brain-dead donors to an intervention group and a control group. After transfer to the intensive care unit, donors in the intervention group received a lung recruitment maneuver according to protocol for 1 hour, whereas the control group did not receive this intervention.

Objectives: Although transplant teams understand the effects of donor characteristics on liver transplant outcomes, few studies have investigated the quality of livers obtained from poisoned donors. The aim of this study was to compare livers procured from poisoned donors with a matched control group.

Materials And Methods: Liver transplant outcomes from poisoned donors and from donors with trauma-induced death (as the control group) were compared using data of an Organ Procurement Unit from 2000 to 2013.

Background: When potential brain dead donors are in line-up for organ retrieval, their loss would be such a disaster. The aim of this study was to detect the occurrence of different disorders leading to pre-retrieval donor's cardiac arrest and loss in order to prevent this energy and money wasting challenge.

Materials And Methods: In this observational study, medical records of potential donors from 2001 to 2016 who were lost after transfer to Organ Procurement Unit (OPU) of Masih Daneshvari Hospital and before organ donation were reviewed and weigh of every responsible disorder was tested.

Objectives: In the organ donation process, screening for serologic markers for a selection of agents is essential to prevent infection transmission. The screening of donors for specific potential infections can never absolutely exclude the risk of transmission. For reevaluation of serology tests, we analyzed results of tests requested for all brain-dead donors.

Objectives: Optimal care of potential donors can lead to successful transplantation. Hemodynamic instability is a common complication in deceased potential donors. The most common underlying causes are hormonal and electrolyte disturbances as well as a hyperinflammatory state, which is rooted in activation of the cytokine cascade.

Objectives: Livers from deceased donors compose nearly 30% of all organ transplants, and about 700 liver transplants are carried out per year. Marginal livers (extended-criteria donors), however, are not usually accepted by recipient teams, and there is only one center for these procedures in Iran. The final decision is made according to criteria that are much more conservative than other globally accepted ones.

Objectives: Donor characteristics can directly affect transplant outcomes. In this study, we examined donor patterns in an organ procurement unit, which covered one-third of the population in Tehran, Iran over the past 12 years (2005 to 2018).

Materials And Methods: Demographic data of donors, including sex, age, cause of death, blood group, outcome of donation, number of organs per donor, and comorbidities (including diabetes mellitus and hypertension), were assessed.

Objectives: In Iran, each medical university can have one organ procurement unit for its own hospital. If the family consents, all patients with brain death must be transferred to the organ procurement unit. When brain death is officially confirmed and the family gives the second consent, the organs are then retrieved in the operating room.

Objectives: Deceased lung donation requires optimum donor care, with lung viability greatly affected by the progress of the disease leading to brain death. In this study, we searched for causes of lung unsuitability for transplant in both primary and secondary evaluations.

Materials And Methods: Primary lung evaluations included chest radiography, oxygen challenge test, and donor clinical and history examination.

Objectives: The method of obtaining family consent for organ donation after occurrence of brain death in Iran is an opt-in process. Because of complicated cultural, legal, religious, and familial structures in Iran, it is not simple to take consent for organ donation in brain death situations. The process needs the professional staff to be experienced and have an appropriate personality to obtain consent.

Objectives: This study investigated a fixed coordinator-directed donor management strategy's impact on donated liver quality, as determined by definitive biopsy results.

Materials And Methods: We collected donated liver biopsy results from donations both before and after implementing a fixed coordinator-directed donor management strategy. This strategy involved full-time attendance by a donor coordinator and continued resuscitation of brain-dead donors.

Objectives: Brain tumors are the most challenging causes of brain deaths due to the lack of pathology results in many cases. It is not uncommon to find a brain tumor in a brain-dead patient with no pathology results or neuroradiology reports available; this would exclude the deceased from organ donation. The mortality that occurs while patients are on transplant wait lists motivated us to find a solution to prevent losing brain-dead patients as potential donors.

Objectives: Organ donor shortage is a worldwide problem, resulting in 10% to 30% mortality rates for patients on wait lists for organ transplant. For brain-dead patients in Iran, it is mandatory for intensive care unit patients with Glasgow Coma Scale below 5/15 to be reported to an organ procurement unit. However, this process has not been functioning effectively.

Intubation stylets are still being used in many medical centers for difficult intubations. Although very rare, it may break inside the trachea during endotracheal intubation despite routine pre-assessments by anesthesiologists and may surprisingly move deep into the tracheobronchial tree. In this case report, we describe a rare complication after stylet or guide-wire intubation in a patient in whom, a broken piece of metal guide remained in his tracheobronchial tree for 3 days.
