Background: Kidney transplantation (KT) is widely accepted as most successful treatment option for patients with end-stage kidney disease (ESKD) for better survival and quality of life for both children as well as adults. Data scarcity on long term outcome of living donor (LD) versus deceased donor (DD) pediatric KT in developing countries prompted us to review our experience. Aims and Objectives: To determine(1) long term graft, (2)patient survival outcome and (3) rejection episodes in LD versus DD pediatric KT in developing country. Patients and Methods: This was a retrospective observational analysis of 151 LD and 37 DD pediatric renal transplants (age ≤18 years) performed at a tertiary care center between 1998 and 2011. This study was under taken to evaluate long term patient and graft survival, rejection episodes and other complications. Demographic details for all patients was retrieved. Kaplan-Meier curves were used for survival analysis. Results: Over a mean follow-up of 4.2 ± 3.61 years, one-, five- and ten- year death-censored graft survival in LDKT was 87.4%, 72.1%, 72.1% and patient survival was 92.5%, 80.9%, 75.1% respectively; 19.8% (n = 30) patients had biopsy proven acute rejection (BPAR) and 17.8% (n = 27) patients died, mainly due to infections (n = 12). In DDKT, over mean follow-up of 3.93 ± 3.5 years, one-, five- and ten-year death-censored graft survival was 90.4%, 86.4% ,73.3% and patient survival was 83.4%, 67.9%, 67.9 %, respectively; 21.6% (n = 8) patients had BPAR and 27% (n =10) patients died, mainly owing to infections (n = 6). Conclusion: LDKT or DDKT in children has acceptable graft function with patient/graft survival over long-term follow-up, encouraging to develop sustained deceased donor program in developing countries. However, infections are major cause of morbidity and mortality.

Objectives Gujarat, Tamil Nadu, Telangana, Maharashtra, Kerala, Chandigarh, and Karnataka are states in India with active programs for deceased donor kidney transplant. We report our experience of 2 decades of deceased donor kidney transplant at the Institute of Kidney Diseases and Research Center, Dr. H. L. Trivedi Institute of Transplantation Sciences, Ahmedabad, Gujarat, India. Materials and methods This single-center retrospective study comprised data from 831 deceased donor kidney transplant recipients between January 1, 1997 and December 31, 2018. Mean recipient age was 38 ± 14 years; 564 were male, and 267 were female. Mean donor age was 45.3 ± 17.13 years; 565 were men, and 266 were women. Results Between January 1, 1997 and March 15, 2020, 5838 kidney transplants were completed, including 4895 living donor kidney transplants, 943 deceased donor kidney transplants, and 440 kidney paired donation transplants. Over the mean follow-up time of 8 ± 5.4 years, patient survival rate was 70% (n = 581) and death-censored graft survival rate was 84% (n = 698). Delayed graft function was shown in 210 patients (25%) and biopsy-proven acute rejection rate in 180 patients (21%). Our experience of favorable outcomes with deceased donor kidney transplants has expanded the donor pool in many ways, including transplant from expanded criteria donors to younger recipients; transplant from older donors to older recipients; donation after cardiac death; successful intercity organ procurement; dual-kidney transplant; en bloc transplant from a pediatric deceased donor; and transplant from brain death deceased donors who died from neurotoxic snakebite, recurrent primary brain tumor, bacterial meningitis, or head injury, or with disseminated intravascular coagulation and deranged renal functions. The pathway to increase organ donation was investigated. Conclusions Deceased donor kidney transplant can achieve acceptable graft function with patient/graft survival, which may encourage the use of this approach to increase the number of available organs.

The population is aging, and the prevalence of chronic wounds is increasing. Because neovascularization is essential for tissue repair and both local and systemic factors affect new blood vessel formation, we hypothesize that altering either pathway would reciprocally enhance wound healing in the aged. To test this hypothesis, p53 was locally suppressed and endothelial progenitor cells (EPCs) were systemically mobilized in a murine model of senescent wound healing.Bilateral 6-mm full-thickness stented wounds were made on the dorsum of Zmpste24 mice. Animals received weekly topical p53 small interfering RNA (siRNA) (n = 25), weekly topical nonsense siRNA (n = 25), daily subcutaneous AMD3100 injections (n = 25), or daily subcutaneous saline injections (n = 25). Wounds were photographically assessed and harvested for reverse transcription polymerase chain reaction, enzyme-linked immunosorbent assay, and immunostaining over 40 days. Circulating EPC levels were measured using fluorescence-activated cell sorting analysis.Local p53 siRNA significantly improved Zmpste24 wound healing (18 ± 2 vs 40 ± 3 days; P ≤ 0.0001). p53 siRNA significantly increased local provasculogenic factors (hypoxia-inducible factor 1 α, stromal cell-derived factor 1 α, and vascular endothelial growth factor; P ≤ 0.05) and decreased local proapoptotic factors (p53, PUMA, and Bax; P ≤ 0.05). Local p53 siRNA also significantly increased the number of circulating EPCs (8 ± 0.2% vs 2.6 ± 0.1%; P ≤ 0.0001). AMD3100 treatment also significantly improved wound healing (20 ± 2 vs 40 ± 3 days; P ≤ 0.0001) and increased EPCs mobilization (7.8 ± 0.4% vs 2.6 ± 0.1%; P ≤ 0.0001). In addition, systemic AMD3100 increased local provasculogenic factors (hypoxia-inducible factor 1 α, stromal cell-derived factor 1 α, and vascular endothelial growth factor; P ≤ 0.05) and decreased local proapoptotic factors (p53, PUMA, and Bax; P ≤ 0.05). Both treatments significantly increased the number of blood vessels in the wound bed (P ≤ 0.0001).The marked delay in Zmpste24 wound healing is significantly improved by local (p53 siRNA) and systemic (AMD3100) treatments. The resulting decrease in proapoptotic factors and increase in provasculogenic factors in the wound bed as well as the increased level of circulating EPCs appear to reverse age-related wound healing impairment by enhancing wound neovascularization.

Introduction: Laparoscopy is increasingly being performed for urologic surgeries either through transperitoneal or retroperitoneal approach. While physiological changes during transperitoneal surgeries have been extensively studied, very few studies have explored the effect of retroperitoneal laparoscopy. Aim: To compare physiological changes that occurred when urologic laparoscopic surgeries were carried out through either transperitoneal or retroperitoneal approach in lateral positions. Primary outcome was respiratory changes and haemodynamic changes were considered secondary outcome. Materials and Methods: This single centre prospective non randomised human study was conducted in 46 healthy individuals undergoing elective urologic laparoscopic surgeries at Dr. H.L. Trivedi Institute of Transplantation Sciences, Ahmedabad, Gujarat, India, from January 2017 to July 2017 and patients were divided into two groups according to the surgical approach used: 1) Transperitoneal (Trans) group; and 2) Retroperitoneal (Retro) group. Compliance, Peak Inspiratory Pressure (PIP), Minute Ventilation (MV), Heart Rate (HR) and Mean Arterial Pressure (MAP) were monitored at defined time interval. Arterial blood gases were also measured to compare Partial Pressure of Arterial Oxygen/Fraction of Inspired Oxygen (PaO2 /FiO2 ) ratio. Chi-square and t-test were used for statistical comparison between the two groups. A p-value

One of the causes of failed epidurals is catheter misplacement. Though various techniques of epidural space identification have been developed, none of them is 100% successful. Here, we present a case of lumbar epidural catheter misplacement in a patient scheduled to undergo right sided open nephrectomy. Catheter was found in the surgical field coming out of psoas major muscle.

Since the first laparoscopic nephrectomy was reported in 1991, this technique has evolved rapidly and laparoscopic donor nephrectomy has emerged as a standard of care in many institutions. However, recipient renal transplantation is still performed by the traditional open approach. There is only one case report of laparoscopic kidney transplantation (LKT) from Spain in 2009. LKT is a technically demanding surgery for a urologist and equally challenging for an anesthesiologist as he has to be vigilant because of the major perturbations in the cardiorespiratory system due to steep trendelenberg position and pneumoperitoneum; additionally, the pneumoperitoneum can have deleterious effects on blood flow and function of the transplanted kidney. We herewith present our experience with anesthesia of the first laparoscopic dual kidney transplantation from a deceased donor performed in our center.

The mechanotransduction mechanisms linking distraction device activation to new bone formation remain unknown. We hypothesize that the tension stress of activation during distraction osteogenesis is transmitted through lacunocanalicular fluid flow to initiate the osteogenic signaling cascade. Adult Sprague-Dawley rats (N = 24) were subjected to mandibular osteotomy and application of an external distraction device. After a 3-day latency period, half the animals (n = 12) underwent device activation at 0.25 mm twice daily for 6 days (total activation, 3 mm), and the other half (n = 12) had no activation. On day 10, the animals were injected with fluorescent reactive red lacunocanalicular tracer before killing. Mandibles were harvested, embedded, and sectioned, and reactive red epifluorescence lacunocanalicular flow was measured. Protein was harvested for focal adhesion kinase 1 (FAK1), NESPRIN1, SUN1, LAMIN A/C, and SMAD1 Western blotting as well as for bone morphogenetic protein (BMP)-2 enzyme-linked immunosorbent assay and alkaline phosphatase assay. Lacunocanalicular fluid flow was significantly greater in the distracted samples (60.5 ± 14 vs 10.3 ± 4 molecules of equivalent soluble fluorochrome per megapixel, P = 0.01). Flow distribution demonstrated the highest lacunocanalicular flow near the center of the distraction gap. Increased lacunocanalicular flow resulted in increased FAK1 (P = 0.009), NESPRIN1 (P = 0.01), SUN1 (P = 0.01), and LAMIN A/C (P = 0.008) expression. Focal adhesion kinase 1 activation in the presence of BMP-2 protein expression (P = 0.001) resulted in increased intranuclear SMAD1 phosphorylation (P = 0.04) and alkaline phosphatase activity (P0.0001). These findings suggest that activation of the distraction osteogenesis device affects cellular response through changes in lacunocanalicular fluid flow.

Introduction: Opioid receptors have been demonstrated in the peripheral nerve endings of afferent neurons. Blockade of these receptors with peripherally administered opioid is believed to result in analgesia. Aim: To evaluate whether buprenorphine added to bupivacaine for wound infiltration can enhance post-operative analgesia via peripheral mechanisms. Materials and Methods: Forty ASA I and II adult patients scheduled for open donor nephrectomy were enrolled in this randomized double blind prospective study. In group A ( n=20) patients, the wound was infiltrated with bupivacaine 0.5% (2 mg/kg) and in group B ( n=20) with bupivacaine 0.5% (2 mg/kg) and buprenorphine (2 μg/kg). All patients were given diclofenac 75 mg IM at 8 h interval. Post-operative quality of analgesia was assessed by VAS (0-10) for 24 h and when VAS > 4 rescue analgesic was administered. Total dose of rescue analgesic and side effects were noted. Results: The time of administration of first rescue analgesic was significantly higher in group B (10.52±5.54 h) as compared to group A (3.275±1.8 h). Mean VAS was significantly lower in group B as compared to group A. The total dosage of rescue analgesic was more in group A as compared to group B patients. Conclusion: Addition of buprenorphine to the local anesthetic significantly prolonged the time to first rescue analgesic requirement and the total consumption of rescue analgesic in 24 h, thus providing evidence in support of the existence of peripheral opioid receptors.

Desaturation after induction of anaesthesia and repositioning due to mucus plug causing atelectasis (lung collapse) is a rare event. We present a case of intraoperative right lung collapse due to mucus plug in a patient undergoing left laparoscopic nephrectomy. Hypoxaemia occurred after the induction of anaesthesia and repositioning. X-ray chest revealed right lung collapse and surgery was subsequently postponed. Lung re-expanded after postural drainage and suction. Postoperatively patient was diagnosed to have retrocardiac bronchiectasis. After preoperative preparation with postural drainage, chest physiotherapy, and antibiotics, the patient underwent surgery uneventfully.

Background Appropriate anesthesia for pediatric renal transplantation requires stable intraoperative hemodynamics, optimal perfusion of the newly transplanted kidney and good analgesia during recovery. The aim of this study was to assess the preliminary application, success and safety of combined epidural and general anesthesia in pediatric renal transplantation in a small cohort. Methods We retrospectively reviewed the anesthesia records of 46 consecutive pediatric patients who received renal transplantation under combined epidural and general anesthesia from January 2003–2007. Results The mean patient age and weight were 13.2 ± 2.4 years and 25.7 ± 5.46 kg, respectively. The infused crystalloids, 20% albumin and red blood cell concentrates were 120 ± 2 mL/kg to achieve a CVP of 13 to 15 mm Hg. Brisk diuresis was observed in all patients. Epidural tramadol (2 mg/kg) provided good postoperative analgesia in 89% patients. 15% patients developed radiological evidence of pulmonary edema, only one required mechanical ventilation for hypoxemia. Minor adverse effects were nausea and vomiting (17.5%) and convulsions (8.5%). No perioperative mortality or major morbidity was recorded. Conclusion Epidural anesthesia is a useful adjunct to general anesthesia due to stable intraoperative haemodynamics and good postoperative analgesia.

Some factors have been identified as contributing to medical errors, such as labels, appearance and location of ampoules. We present a case of accidental injection of tranexamic acid instead of Bupivacaine during spinal anaesthesia. One minute after the injection of 3 mL of the solution, the patient developed myoclonus of her lower extremities. Accidental intrathecal injection of the wrong drug was suspected and a used ampoule of tranexamic acid was discovered in the trash can. The ampoules of Bupivacaine (5 mg/mL, trade name “Sensovac Heavy”) and tranexamic acid (500 mg/mL, Trade name “Nexamin”) were similar in appearance. Her myoclonus was successfully treated with phenytoin, sodium valproate, thiopental sodium infusion, midazolam infusion and supportive care of haemodynamic and respiratory systems. The surgery was temporarily deferred. The patient's condition progressively improved to full recovery.

Background Enthusiasm for the deep inferior epigastric artery perforator (DIEP) flap for autologous breast reconstruction has grown in recent years. However, this flap is not performed at all centers or by all plastic surgeons for breast reconstruction, and it is unclear whether practice patterns have measurably changed. This study aimed to (1) evaluate changing trends in breast flap use in the United States in recent years and (2) identify how these trends have affected charges and costs associated with autologous breast reconstruction. Methods Patients undergoing autologous breast reconstruction [latissimus dorsi (LD), pedicled transverse rectus abdominus myocutaneous (pTRAM), free TRAM (fTRAM), and DIEP] were identified using the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database (2009-2011). A total of 19,182 hospital discharges were reviewed. Patient demographics, hospital teaching center status, payer status, length of stay, total charges, and total costs per discharge were reviewed. Statistical analysis was performed using linear regression, t test, and analysis of variance models. Results Between 2009 and 2011, the total number of discharges did not change significantly. Patient age distribution was similar for all flap groups. For individual flaps, there was a significant increase in DIEP flaps (P = 0.03), with a decreasing trend for other abdominal-based flaps. The patients receiving DIEP flap breast reconstruction were covered by private insurance at a higher rate than all other flap procedures (P = 0.03), whereas other potential cost determinants did not differ significantly between the groups. The mean charge per flap was $40,704 for LD, $51,933 for pTRAM, $69,909 for fTRAM, and $82,320 for DIEP. The mean cost per flap was $12,017 for LD, $15,538 for pTRAM, $20,756 for fTRAM, and $23,616 for DIEP. Conclusions Between 2009 and 2011, the total amount of autologous breast reconstruction discharges was relatively stable, but the number of DIEP flaps increased significantly. Review of the Healthcare Cost and Utilization Project Nationwide Inpatient Sample data shows that, compared with LD, pTRAM, and fTRAM flaps, the DIEP flap is associated with higher charges and costs.

BACKGROUND: The transfer of patients with hand injuries involves a commitment of substantial resources, emphasizing the importance of understanding factors that may influence referral patterns. Anecdotal experience suggests that the likelihood of transfer increases during nights and weekends. This study aimed to analyze patterns of hand trauma transfers to Duke University Medical Center with respect to timing and patient insurance status. METHODS: The authors performed a retrospective chart review and analysis of 1147 consecutive patient transfers from 2005 to 2010 at a single level 1 university trauma center. Data categories included timing of transfer, patient demographics, insurance status, diagnosis, and procedures performed. Statistical analysis was performed using SAS software (SAS Institute Inc., Cary, N.C.). RESULTS: Of the patient sample, 39.8 percent was female, 30 percent were African American, and 57.3 percent were white. Contrary to our expectations, transfers were more likely during the day (p = 0.0001). Likewise, patients were more likely to present on weekdays than on weekends (p =.001). Although uninsured patients were not disproportionately represented overall, they were more frequently transferred at night (p = 0.0001), despite having the same complexity of injuries as privately insured patients. Conversely, patients with private insurance were less likely to be transferred at night (p = 0.0001). CONCLUSIONS: Similar to studies in other surgical specialties, this analysis demonstrates significant associations between insurance status and hand injury transfer patterns. The current climate, including declining numbers of surgeons willing to provide emergency hand care, diminishing reimbursements, and an expanding uninsured patient population, threatens to exacerbate these concerning trends in trauma patient management.

Background: Epidural analgesia with opioid provides good control of postoperative pain in cesarean section, thereby improving the mother's ability to mobilize and interact with her newborn infant. Aim: The aim of this study is to evaluate and compare the analgesic actions and side effects of epidural analgesia with sufentanil, morphine or combination of the two after cesarean section. Materials and Methods: 60 women undergoing elective cesarean section were allocated into three groups of 20 each in a randomized blinded fashion. Epidural analgesia was administered with sufentanil 50 mcg in Group S; morphine 4 mg in Group M; and, a combination of sufentanil 25 mcg and morphine 2 mg was used in Group SM. Analgesic efficacy in terms of onset of action and duration of analgesia was assessed by using the Visual Analog Scale (0 to 10 cm) for 24 hours. Number of opioid doses needed in 24 hours was noted. Side effects like respiratory depression /excessive sedation, pruritus and nausea were recorded. Results: Onset of action were at 7.6 ± 1.5 minutes in group S, 67.6 ± 1.5 minutes in group M and 12.2 ± 2.6 minutes in group SM. Duration of analgesia was longer in group M 17.5 ± 1.9 hours and SM 13.8 ± 1.6 hours than in group S 5.2 ± 1.2 hours. More doses of analgesia were required in group S compared to group M and SM. Side effects were comparable in the three groups. Conclusion: Epidural administration of a combination of sufentanil and morphine offered the advantage of faster onset of action and longer duration of analgesia as compared to the two drugs administered alone.

Case report A 10 year old girl was admitted with a history of two episodes of seizures within a period of 6 months associated with tremors and weakness in the left upper and lower limbs. She was treated with phenytoin sodium and dexamethasone, both given orally. On examination, she was conscious, oriented and neurological examination revealed left hemiparesis with motor power grade of 5/6. Her blood investigations and ultrasonography of abdomen were normal. Computed tomography (CT) scan of the brain showed a porencephalic cyst communicating with the right ventricle with a marked midline shift (Figure 1). Magnetic resonance imaging (MRI) of brain showed a well-defined mass lesion 82 x 73 mm in axial, 67 x 68 mm in coronal and 78 x 70 mm in sagittal planes in right parietal basal ganglia area with mass effect and without perilesional vasogenic oedema and without restriction of diffused weighted imaging. Surgical removal of the cyst was done. The cyst ruptured during the course of surgery and for the prevention of anaphylactic reaction, injection chlorpheniramine maleate and injection hydrocortisone were given. The cyst with the contents was successfully removed. The diagnosis of hydatid cyst was established by histopathology.

BACKGROUND The graying of our population has motivated the authors to better understand age-related impairments in wound healing. To increase research throughput, the authors hypothesized that the Hutchinson-Gilford progeria syndrome Zmpste24-deficient (Zmpste24(-/-)) mouse could serve as a model of senescent wound healing. METHODS Using a stented excisional wound closure model, the authors tested this hypothesis on 8-week-old male Zmpste24(-/-) mice (n = 25) and age-matched male C57BL/6J wild-type mice (n = 25). Wounds were measured photogrammetrically and harvested for immunohistochemistry, enzyme-linked immunosorbent assay, and quantitative real-time polymerase chain reaction, and circulating vasculogenic progenitor cells were measured by flow cytometry. RESULTS Zmpste24(-/-) mice had a significant delay in wound closure compared with wild-type mice during the proliferative/vasculogenic phase. Zmpste24(-/-) wounds had decreased proliferation, increased 8-hydroxy-2'-deoxyguanosine levels, increased proapoptotic signaling (i.e., p53, PUMA, BAX), decreased antiapoptotic signaling (i.e., Bcl-2), and increased DNA fragmentation. These changes correlated with decreased local vasculogenic growth factor expression, decreased mobilization of bone marrow-derived vasculogenic progenitor cells, and decreased new blood vessel formation. Age-related impairments in wound closure are multifactorial. CONCLUSIONS The authors' data suggest that the Hutchinson-Gilford progeria syndrome Zmpste24(-/-) progeroid syndrome shares mechanistic overlap with normal aging and therefore might provide a uniquely informative model with which to study age-associated impairments in wound closure.

BACKGROUND Lipoaspirate centrifugation creates graded density of adipose tissue. High-density fat contains more vasculogenic cytokines and progenitor cells and has greater graft survival than low-density fat. The authors hypothesize that accelerating the bone marrow-derived progenitor cell response to injected low-density fat will improve its graft survival. METHODS Male 8-week-old FVB mice (n=60) were grafted with either high-density (n=20) or low-density (n=40) human lipoaspirate. Half of the mice receiving low-density fat (n=20) were treated with a stem cell mobilizer for 14 days. Grafted fat was harvested at 2 and 10 weeks for analysis. RESULTS Low-density fat, low-density fat plus daily AMD3100, and high-density fat had 26±3.0, 61.2±7.5, and 49.6±3.5 percent graft survival, respectively, at 2 weeks (low-density fat versus low-density fat plus daily AMD3100 and low-density fat versus high-density fat, both p

Background: As an anesthetic adjuvant dexmedetomidine has been shown to provide good perioperative hemodynamic stability with minimum alveolar concentration sparing effect on inhalational anesthetic agents during laparoscopic surgeries performed under general anesthesia. Aim: The study was planned to investigate the effects of dexmedetomidine on attenuation of hemodynamic changes and requirements of intra-operative analgesic and inhalational anesthetic during laparoscopic surgeries and its postoperative side effects. Materials and Methods: A total of 70 patients scheduled for elective laparoscopic surgeries were randomized to receive bolus infusion of dexmedetomidine (group D) or saline (group S) 1 mcg/kg/h, followed by continuous infusion of the same, at the rate of 0.5 mcg/kg/h. Anesthesia was maintained with nitrous oxide in oxygen, muscle relaxant and isoflurane. Supplementation with end-tidal isoflurane was considered when heart rate (HR) and mean arterial blood pressure (BP) exceeded 20% of the baseline value. Hemodynamics, end-tidal isoflurane concentration and adverse events were recorded. Results: Intra-operative mean HR and mean BP in group D were lower than group S (P < 0.05) throughout the laparoscopy surgery. Requirement of intra-operative fentanyl, end-tidal isoflurane and postoperative tramadol were significantly more in group S compared to group D (P < 0.05) Statistically significant nausea and vomiting were noted in group S. Undue sedation and other adverse effects are comparable in both the groups. Conclusion: Dexmedetomidine as an adjuvant in general anesthesia for laparoscopic surgeries provided a stable hemodynamic profile in the perioperative period and effectively blunted pressor response to intubation and extubation, leading to minimal requirements for additional analgesics and potent inhalational agents. There were less adverse events.

Adult onset congenital diaphragmatic hernia (CDH) is uncommon but not rare. Morgagni hernia is a rare variant of CDH. The defect tends to be small and patients may remain asymptomatic and diagnosed incidentally. When these patients become symptomatic, they usually present with gastrointestinal and cardiorespiratory symptoms or sometimes as an emergency due to obstruction or strangulation of herniated viscera. Chest radiograph, computed tomography scan, and magnetic resonance imaging are the imaging modalities used for diagnosis of CDH. Cardiopulmonary compromise due to mass effect of hernial contents on lungs, heart and great vessels, and obstruction or strangulation of herniated viscera poses the special challenge before anesthesiologists. Our patient was diagnosed to have Morgagni hernia, at the age of 72 years and underwent laparotomy for the same. This case highlights the key feature of the successful anesthetic management of adult onset CDH.

In a developing country such as India, deceased donor renal transplantation (DDRTx) accounts for only about 1% of all renal transplants (RTx). Our institute initiated an intercity DDRTx in the year 2006, which significantly increased the number of RTx. We retrieved 74 kidneys from 37 deceased donors from various cities of Gujarat from January 2006 to December 2009. We transplanted the allografts in 66 recipients and a retrospective analysis of the donor profile and management and recipient outcome was performed. The mean age of the donors was 43.3 ± 18.8 years. The causes of death included road traffic accident in 51.35% of the donors and cerebrovascular stroke in 48.65% of the donors; 83.78% of the donors required ionotropes for hemodynamic stability in addition to vigorous intravenous fluid replacement. The average urine output of the donors was 350 ± 150 mL. The organs were perfused and stored in HTK solution. The mean cold ischemia time (CIT) was 9.12 ± 5.25 h. The mean anastomosis time in the recipient was 30.8 ± 8.7 min. 57.6% of the recipients established urine output on the operating table and 42.4% developed delayed graft function. At the end of 1 month after transplantation, the mean serum creatinine was comparable to the Ahmadabad city DDRTx, although the CIT was significantly longer in the intercity patients. Intercity organ harvesting is a viable option to increase the donor pool. Distance may not be an impediment, and good recipient outcome is possible in spite of prolonged CIT in case of proper harvesting and preservation.
