Autopsy: quality assurance in the ICU

Objective: To examine the correlation between the clinical diagnosis and autopsy findings in adult patients who died in an intensive care unit (ICU). To determine the rate of agreement of the basic and terminal causes of death and the types of errors in order to improve quality control of future care,Design, Retrospective study.Setting: Adult ICU in a university hospital.Patients: 30 adult patients who died in the ICU. with the exclusion of medicolegal cases.Methods and main results: Anatomo-clinical meetings were held to analyze the pre- and postmortem correlations in 30 consecutive autopsies at the ICU of the University Hospital, School of Medicine of Botucatu/ UNESP, from January 1994 to January 1997. The rate of correct clinical diagnoses of the basic cause was 66.7 %; in 23.3 % of cases, if the correct diagnosis was made, management would have been different, as would have been the evolution of the patient's course (Class I error): in 10 % of the cases the error would not have led to a change in management (Class II error). The rate of correct clinical diagnoses of terminal cause was 80 %.Conclusions: the rate of recognition of the basic cause was 66.7 %, which is consistent with the literature, but the Class I error rate was higher than that reported in the literature.

Species distribution and antifungal susceptibility patterns of Candida spp. bloodstream isolates from a Brazilian tertiary care hospital

In this work, we collect data from surveys of bloodstream Candida isolates performed in Brazil from 1996 to 2004. Besides, we analyzed the species distribution of bloodstream Candida isolates together with potential risk factors for candidemia and the susceptibility profile of these isolates in patients from Hospital das Clinicas in Goiaonia city, Brazil. Blood samples were collected in the admission day and on every 7 days, in the intensive care unit (ICU) of a tertiary hospital. Candida isolates were identified by standard protocols that included germ tube formation, chlamydoconidia production on cornmeal agar and sugar fermentation and assimilation tests. Data of patients were recorded and analyzed according to age at the time of diagnosis, gender and presence of potential risk factors. Statistical analysis was used to determine if the time of hospital permanence increased Candida colonization in ICU patients' blood. The antifungal susceptibility testing was performed by broth microdilution method according to document NCCLS/CLSI M27-A2. Among the 345 blood samples cultured, candidemia was recovered in 33 patients, which were isolated 51.5% of Candida non-albicans. Fungemia was associated with long-term hospitalization. Fluconazole, itraconzole, voriconazole and amphotericin B exhibited a potent activity against all isolates of Candida. Voriconazole MICs were much low for all isolates tested. This work confirms data of increase of Candida non-albicans species in bloodstream in ICU and shows that voriconazole in vitro activity was higher than those of itraconazole, fluconazole and amphotericin B.

The frequency of pharmacological pain relief in university neonatal intensive care units

Objective: To evaluate the use of drugs to relieve the pain of invasive procedures newborn infants cared for at a university hospital NICU. Methods: A prospective cohort study of all newborn infants hospitalized in four NICU during October 2001. The following data were collected: demographic data of the hospitalized newborn infants; clinical morbidity; number of potentially painful procedures and frequency of analgesic administration. Factors associated with the use of analgesia in this cohort of patients were studied by multiple linear regression using SPSS 8.0. Results: Ninety-one newborn infants were admitted to the NICU during the study period (1,025 patient-days). Only 25% of the 1,025 patient-days received systemic analgesia. No specific drugs were administered to relieve acute pain during any of the following painful events: arterial punctures, venous, capillary and lumbar punctures or intubations. For chest tube insertion, 100% of newborn infants received specific analgesia. For the insertion of central catheters 8% of the newborn infants received painkillers. Only nine of the 17 newborn infants that underwent surgical procedures received any analgesic dosage during the postoperative period. For 93% of patients under analgesia the drug of choice was fentanyl. The presence of mechanical ventilation increased the chance of newborn infants receiving painkillers by 6.9 times and the presence of chest tube increased this chance by five times. Conclusion: It is necessary to train health professionals in order to bridge the gap between scientific knowledge regarding newborn infant pain and clinical practice.

CONCLUSÕES: O bloqueio bilateral contínuo periférico com infusão de bupivacaína a 0,1% com bombas elastoméricas é um procedimento seguro e efetivo em adultos.

Early nephrology consultation can have an impact on outcome of acute kidney injury patients

Background. Patients who develop acute kidney injury (AKI) in the intensive care unit (ICU) have extremely high rates of mortality and morbidity. The objectives of this study were to compare clinical and laboratory characteristics of AKI patients evaluated and not evaluated by nephrologists in ICU and generate the hypothesis of the relationship between timing of nephrology consultation and outcome.Methods. We explored associations among presence and timing of nephrology consultation with ICU stay and in-ICU mortality in 148 ICU patients with AKI at a Brazilian teaching hospital from July 2008 to May 2010. Multivariable logistic regression was used to adjust confounding and selection bias.Results. AKI incidence was 30% and 52% of these AKI patients were evaluated by nephrologists. At multivariable analysis, AKI patients evaluated by nephrologists showed higher Acute Tubular Necrosis-Index Specific Score and creatinine level, more dialysis indications, lower urine output and longer ICU stay. The mortality rate was similar to AKI patients who were not evaluated. Nephrology consultation was delayed (>= 48 h) in 62.3% (median time to consultation, 4.7 days). Lower serum creatinine levels (P - 0.009) and higher urine output (P = 0.002) were associated with delayed consultation. Delayed consultation was associated with increased ICU mortality (65.4 versus 88.2%, P < 0.001).Conclusions. In AKI, patients evaluated by nephrologists seem to be more seriously ill than those not evaluated and present similar mortality rate. The delayed nephrology consultation can be associated with increased ICU mortality.

Estudo prospectivo observacional sobre a incidência de injúria renal aguda em unidade de terapia intensiva de um hospital universitário

OBJETIVO: Analisar comparativamente características clínicas e evolução de pacientes com e sem IRA adquirida em UTI geral de um hospital universitário terciário. MÉTODO: Estudo prospectivo observacional com 263 pacientes acompanhados diariamente durante a internação em UTI Geral do Hospital das Clínicas da Faculdade de Medicina de Botucatu no período de julho de 2007 a abril de 2008. RESULTADOS: A incidência de IRA foi de 31,2%. Os grupos foram semelhantes quanto ao sexo e diferiram quanto à etiologia da admissão em UTI (sepse: 31,7% x 13,1%, p < 0,0001, pós-operatório: 11% x 43%, p < 0,0001), idade (59,6 ± 18,1 x 50,2 ± 18,6 anos, p < 0,0001), APACHE II: (21 ± 11,1 x 11 ± 4,8, p = 0,002), oligúria (67,7% x 4,5%, p < 0,0001), presença de ventilação mecânica (81,7 x 57,7%, p = 0,0014), uso de drogas vasoativas (62,2 x 32,6%, p < 0,0001) e enfermaria de procedência (PS: 22 x 14,5%, p = 0,02 e centro cirúrgico: 42,7 x 62,6%, p = 0,03). Quanto às comorbidades, os grupos foram diferentes quanto à presença de HAS e IRC (42,6 x 35,9%, p = 0,005 e 15,8 x 2,1%, p = 0,04, respectivamente) e semelhantes quanto à presença de diabetes e ICC (19,5 x 11%, ns e 6 x 1,1%, ns, respectivamente). A mortalidade foi superior nos pacientes que contraíram IRA (62,1 x 16,5%, p < 0,0001). CONCLUSÃO: A incidência de IRA é elevada em UTI e presente em pacientes com parâmetros clínicos e índices prognósticos de maior gravidade, o que justifica a maior mortalidade observada neles.

Comparação entre dois testes de rastreamento do diabetes gestacional e o resultado perinatal

OBJETIVO: comparar dois testes de rastreamento para diabetes e seus resultados com o resultado da gestação. MÉTODOS: no total, 279 pacientes foram submetidas a dois testes de rastreamento do diabetes gestacional - associação glicemia de jejum e fatores de risco (GJ + FR) e o teste de tolerância à glicose simplificado (TTG50g). O rastreamento pela associação GJ + FR caracterizou-se pela dosagem da glicemia de jejum e anamnese para identificação dos fatores de risco na primeira consulta de pré-natal. O TTG50g foi realizado entre a 24ª e a 28ª semana de gestação e caracterizou-se pela dosagem das glicemias plasmáticas em jejum e uma hora após a sobrecarga oral com 50 g de glicose. Os resultados, positivo e negativo, foram relacionados ao resultado da gestação. Foram consideradas variáveis dependentes: via de parto, idade gestacional, peso e índice ponderal ao nascimento, índices de Apgar <7 no 1º e 5º minutos, necessidade de Unidade de Terapia Intensiva (UTI), tempo de permanência hospitalar e óbito neonatal. Empregou-se o teste t de Student, admitindo-se 5% como limite de significância para calcular a diferença de proporção de das médias. RESULTADOS: apenas dois resultados perinatais estudados foram diferenciados pelos testes. O TTG50g alterado esteve associado à maior proporção de cesárea (58,7 versus 34,3%) e a associação GJ + FR positiva, maior taxa de prematuridade (15,4 versus 5,4%). As demais variáveis não foram diferentes nas pacientes com testes de rastreamento positivo e negativo. CONCLUSÕES: Apesar da relação entre a prematuridade e associação GJ + FR positiva e aumento de cesárea e TTG50g alterado, seria falha crítica aceitá-los como definitivos. Entre outras explicações, múltiplos fatores intercorrentes e as características próprias dos testes de rastreamento devem ser consideradas.

Analgesia pós-operatória para crianças com menos de 1 ano: análise retrospectiva

JUSTIFICATIVA E OBJETIVOS: A dor pós-operatória continua sendo uma das principais complicações pós-operatórias e motivo de desconforto, principalmente em crianças. O objetivo deste estudo foi avaliar o uso de analgésicos desde o término da cirurgia até a alta da sala de recuperação pós-anestésica (SRPA), como medida terapêutica ou profilática, para crianças com menos de 1 ano de idade. MÉTODO: Utilizando o banco de dados do Departamento de Anestesiologia, foi realizada análise retrospectiva, envolvendo o período de janeiro de 2000 a abril de 2001, das anestesias de crianças menores que 1 ano de idade submetidas a procedimentos cirúrgicos diversos, avaliando aspectos relacionados à analgesia pós-operatória. RESULTADOS: No período do estudo, foram anestesiadas 402 crianças menores que 1 ano, sendo que 194 (48,2%) não receberam analgésicos e 208 (51,8%) receberam. Com relação ao uso ou não de analgésicos, foi observado o que se segue: Sem analgésicos: (1) Idade: até 1 mês, 68/99; entre 1 e 6 meses, 53/126; entre 6 meses e 1 ano, 73/177. (2) Peso: 6,7 ± 3,1 kg (3). Sexo: masculino, 106/240; feminino, 88/162. (4) Estado físico ASA: ASA I, 69/187; ASA II, 56/113; ASA III, 46/79; ASA IV, 23/23. (5) Anestesia peridural sacral: 3/4. (6) Tempo de anestesia: 106 ± 32 minutos. (7) Encaminhamento para unidade de terapia intensiva (UTI): 93/119. Uso de analgésicos: (1) Idade: até 1 mês, 31/99; entre 1 e 6 meses, 73/126; entre 6 meses e 1 ano, 104/177. (2) Peso: 9 ± 2,3 kg. (3) Sexo: masculino, 134/240; feminino, 74/162. (4) Estado físico ASA: ASA I, 118/187; ASA II, 57/113; ASA III, 33/79; ASA IV, 0/23. (5) Anestesia peridural sacral: 1/4. (6) Tempo de anestesia: 130 ± 38 minutos. (7) Encaminhamento para UTI: 26/119. Os fármacos empregados para promover analgesia foram: dipirona (60,6%), dipirona + tramadol (25,5%), dipirona + nalbufina (5,3%), tramadol (3,8%), nalbufina (3,8%), meperidina (0,5%) e fentanil (0,5%). CONCLUSÕES: Utilizar analgésicos em crianças desde o término da cirurgia até a alta da SRPA não foi habitual, principalmente nas crianças menores e mais graves e em procedimentos cirúrgicos mais rápidos. O uso de dipirona, isoladamente, ou a associação dipirona/tramadol, foram as drogas analgésicas mais freqüentemente empregadas.

Edema agudo de pulmão de pressão negativa como complicação grave de síndrome de apneia obstrutiva do sono em crianças. Relatos de casos

Introduction: Obstructive sleep apnea syndrome is related to cardiopulmonary complications in children. It is important to know its patophysiology and possible complications to help reduce risks in this group. Aims: To report three cases of severe cardiorespiratory complications of obstructive sleep apnea managed in the intensive care unit (ICU). Case report: Two children with no previous diagnosis of obstructive sleep apnea syndrome suffered acute congestive heart failure and acute lung oedema with need of ICU and improved after adenotonsillectomy. In a third case, the patient had acute lung oedema as a complication after adenotonsillectomy. Conclusions: Paediatricians and otolaryngologists must be aware of the clinical manifestations of severe sleep apnea. Early referring to treatment and special attention at pre and post surgical periods are essentials to avoid serious complications.

Atuação fisioterapêutica na lesão medular em unidade de terapia intensiva: Atualização de literatura

Objective. Collate and update knowledge in relation to physical therapy in spinal cord injury (SCI) in the intensive care unit (ICU). Method. We performed a literature update in the databases Lilacs, PubMed and Scielo, crossing the descriptors spinal cord injury, cinesiotherapy, physiotherapy, mobilization, rehabilitation, intensive care unit, respiratory therapy and electrotherapy in the period of 2005 to 2010. Results. We found 21 studies, however, only five articles met the inclusion criteria. Kinesiotherapy is essential since the phase of spinal shock, since it favors the maintenance of joint range of motion and flexibility, and to prevent circulatory complications caused/ resulted from prolonged immobilization in bed. Respiratory therapy promotes bronchial hygiene, correction of abnormal respiratory patterns and respiratory diseases. The electrotherapy is a feature still little used by physiotherapists in the intensive care units. Conclusions. The physical therapy in SCI in ICU is focused on motor rehabilitation through kinesiotherapy and intervention through the respiratory bronchial hygiene and training of respiratory muscles. New treatment modalities such as electrotherapy, there have been in intensive environment, there is a need for more studies to confirm benefits and risks of this feature in the spinal cord.

A randomized clinical trial of high volume peritoneal dialysis versus extended daily hemodialysis for acute kidney injury patients

Background: Acute kidney injury (AKI) requiring dialysis in critically ill patients is associated with an in-hospital mortality rate of 50-80 %. Extended daily hemodialysis (EHD) and high volume peritoneal dialysis (HVPD) have emerged as alternative modalities. Methods: A double-center, randomized, controlled trial was conducted comparing EHD versus HVPD for the treatment for AKI in the intensive care unit (ICU). Four hundred and seven patients were randomized and 143 patients were analyzed. Principal outcome measure was hospital mortality, and secondary end points were recovery of renal function and metabolic and fluid control. Results: There was no difference between the two groups in relation to median ICU stay [11 (5.7-20) vs. 9 (5.7-19)], recovery of kidney function (26.9 vs. 29.6 %, p = 0.11), need for chronic dialysis (9.7 vs. 6.5 %, p = 0.23), and hospital mortality (63.4 vs. 63.9 %, p = 0.94). The groups were different in metabolic and fluid control. Blood urea nitrogen (BUN), creatinine, and bicarbonate levels were stabilized faster in EHD group than in HVPD group. Delivered Kt/V and ultrafiltration were higher in EHD group. Despite randomization, there were significant differences between the groups in some covariates, including age, pre-dialysis BUN, and creatinine levels, biased in favor of the EHD. Using logistic regression to adjust for the imbalances in group assignment, the odds of death associated with HVPD was 1.4 (95 % CI 0.7-2.4, p = 0.19). A detailed investigation of the randomization process failed to explain the marked differences in patient assignment. Conclusions: Despite faster metabolic control and higher dialysis dose and ultrafiltration with EHD, this study provides no evidence of a survival benefit of EHD compared with HVPD. The limitations of this study were that the results were not presented according to the intention to treat and it did not control other supportive management strategies as nutrition support and timing of dialysis initiation that might influence outcomes in AKI. © 2012 Springer Science+Business Media Dordrecht.
