Perioperative complications and mortality in elderly patients following surgery for femoral fracture: prospective observational study / Complicações perioperatórias e mortalidade em pacientes idosos submetidos a cirurgia para correção de fratura de fêmur: estudo prospectivo observacional

Abstract Background and objectives: Perioperative management of femoral fractures in elderly patients has been studied to determine modifiable causes of complications and death. The aim of this study was to evaluate the mortality rate and its causes in the elderly population with FF. We also evaluated perioperative complications and their association with postoperative mortality. Method: In this prospective and observational study, we evaluated 182 patients, by questionnaire and electronic medical record, from the moment of hospitalization to one year after surgery. Statistical analyzes using the multivariate Cox proportional hazards model and Kaplan-Meier curves were performed to detect independent mortality factors. Results: Fifty-six patients (30.8%) died within one year after surgery, and the main cause of death was infection followed by septic shock. The main complication, both preoperatively and postoperatively, was hydroelectrolytic disorder. For every one-unit (one-year) increase in age, the odds ratio for death increased by 4%. With each new preoperative complication, the odds ratio for death increased by 28%. Patients ASA III or IV had a 95% higher odds ratio for death than patients ASA I or II. Conclusions: Increasing age and number of preoperative complications, in addition to ASA classification III or IV, were independent factors of increased risk of death in the population studied. The mortality rate was 30.8%, and infection followed by septic shock was the leading cause of death.

Resumo Justificativa e objetivos: O manejo perioperatório das fraturas de fêmur em pacientes idosos tem sido estudado com o intuito de determinar causas modificáveis de complicações e óbito. Este estudo tem por objetivo avaliar taxa de mortalidade e suas causas na população idosa com fraturas de fêmur. Avaliamos também complicações perioperatórias e sua associação com mortalidade pós-operatória. Método: Neste estudo prospectivo e observacional, avaliamos 182 pacientes, por questionário e prontuário eletrônico, desde o momento da internação até um ano após a cirurgia. Análises estatísticas pelo modelo multivariado de riscos proporcionais de Cox e curvas de Kaplan-Meier foram feitas para detectar fatores independentes de mortalidade. Resultados: Cinquenta e seis pacientes (30,8%) obituaram em até um ano de pós-operatório, sendo que a principal causa determinada de óbito foi infecção seguida de choque séptico. A principal complicação, tanto pré quanto pós-operatória, foi distúrbio hidroeletrolítico. Para cada aumento de uma unidade (em ano) na idade, a razão de chance de vir a óbito aumentou em 4%. A cada nova complicação pré-operatória apresentada, a razão de chance de óbito aumentou em 28%. Os pacientes ASA III ou IV apresentaram razão de chance de óbito, em um ano, 95% maior do que aqueles ASA I ou II. Conclusões: O aumento da idade e do número de complicações pré-operatórias, além da classificação de ASA III ou IV, foram fatores independentes de risco aumentado de óbito na população estudada. A taxa de mortalidade foi de 30,8%, sendo que a infecção seguida de choque séptico foi a principal causa determinada de óbito.

[Amaurosis and contralateral cranial nerve pairs III and VI paralysis after peribulbar block - case report]. / Amaurose e paralisia do III e do VI pares cranianos contralaterais após bloqueio peribulbar ­ relato de caso.

BACKGROUND AND OBJECTIVES: Peribulbar anesthesia has emerged as a safer option compared with intraconal retrobulbar block. Still, peribulbar anesthesia may not be considered without risk. Numerous complications have been described when performing this technique. This report aims to describe a rare case of amaurosis and contralateral paralysis while attempting to perform a peribulbar anesthesia. CASE REPORT: Male patient, 75-year old, physical status ASA II, undergoing cataract surgery by phacoemulsification with intraocular lens implantation. Sedated with fentanyl and midazolam and subjected to peribulbar anesthesia. There were no complications during surgery. After finishing the procedure, the patient reported lack of vision in the contralateral eye. Akinesia of the muscles innervated by the cranial nerve pairs III and VI, ptosis, and medium-sized pupils unresponsive to light stimulus were observed. Four hours after anesthesia, complete recovery of vision and eyelid and eyeball movements was seen in the non-operated eye. CONCLUSIONS: During peribulbar anesthesia, structures located in the intraconal space can be accidentally hit leading to complications such as described in the above report. Following the technical guidelines and using appropriate size needles may reduce the risk of such complication, but not completely.

Quality of recovery from anesthesia of patients undergoing balanced or total intravenous general anesthesia. Prospective randomized clinical trial.

STUDY OBJECTIVES: The aim of the present study was to assess the quality of recovery from anesthesia of patients subjected to otorhinolaryngological (ORL) surgery under balanced or total intravenous general anesthesia by means of Quality of Recovery-40 (QoR-40) questionnaire. DESIGN: Prospective randomized clinical trial. SETTING: The setting is at an operating room, a postoperative recovery area, and a hospital ward. PATIENTS: One-hundred thirty American Society of Anesthesiologists physical status I or II patients scheduled to undergo general anesthesia for ORL interventions under remifentanil, in combination with sevoflurane (balanced technique) or propofol (total intravenous anesthesia). MEASUREMENTS: Occurrence of nausea, vomiting, body temperature less than 36°C, and length of stay in the postanesthesia care unit were recorded. The QoR-40 was administered by an investigator blind to group allocation 24 hours after surgery. The quality of recovery, as assessed by the score on the QoR-40, was compared between the groups. MAIN RESULTS: There is no difference regarding the QoR-40 score among intravenous and inhalation anesthesia groups (190.5 vs 189.5, respectively; P=.33). Similarly, among the 5 dimensions of the QoR-40, the scores were comparable between the groups. Incidence of hypothermia (P=.58), nauseas or vomits (P=.39), and length of surgery (P=.16) were similar among groups. The evaluation of pain intensity (P=.80) and dose of morphine use in the postanesthesia care unit (P=.4) was also comparable between groups. CONCLUSIONS: The quality of recovery from anesthesia assessed based on the patients' perception did not differ between the ones subjected to either inhalation or intravenous general anesthesia for ORL surgery based on QoR-40 questionnaire assessment.

Evaluation of pathogenic fungi occurrence in traumatogenic structures of freshwater fish.

INTRODUCTION: Fungal infections in human skin, such as sporotrichosis, can occur after fish induced trauma. This work aimed to identify fungi in freshwater fish that are pathogenic to humans. METHODS: Extraction of dental arches from Serrassalmus maculatus (piranha) and Hoplias malabaricus (wolf fish), stings from Pimelodus maculatus (mandis catfish), dorsal fin rays from Plagioscion spp. (corvina) and Tilapia spp., for culture in Mycosel agar. Some cultures were submitted to DNA extraction for molecular identification by sequencing ITS-5.8S rDNA. RESULTS: Cultures identified most yeast as Candida spp., while sequencing also permitted the identification of Phoma spp. and Yarrowia lipolytica. CONCLUSIONS: While the search for S. schenckii was negative, the presence of fungus of the genera Phoma and Candida revealed the pathogenic potential of this infection route. The genus Phoma is involved in certain forms of phaeohyphomycosis, a subcutaneous mycosis caused by dematiaceous fungi, with reports of infections in human organs and systems. Traumatizing structures of some freshwater fish present pathogenic fungi and this may be an important infection route that must be considered in some regions of Brazil, since there are a large number of a fisherman in constant contact with traumatogenic fish.

INTRODUÇÃO: Infecções fúngicas na pele humana (como a esporotricose) podem se manifestar após traumatismos por peixes. O objetivo deste trabalho é procurar fungos patogênicos para o homem em peixes fluviais. MÉTODOS: Extração de arcadas dentárias Serrassalmus maculatus (piranha) e Hoplias malabaricus (traíra), ferrões de Pimelodus maculatus (mandis), raios da nadadeira dorsal de Plagioscion spp. (corvina) e Tilapia spp. para a realização do cultivo em agar Mycosel. Algumas culturas foram submetidas à extração de DNA para a identificação molecular pelo seqüenciamento da região ITS-5.8S do rDNA. RESULTADOS: As culturas mostraram que a maioria das leveduras era Candida spp. e o sequenciamento também permitiu a identificação de Phoma spp. e Yarrowia lipolytica. CONCLUSÕES: Embora a pesquisa para S. schenckii tenha sido negativa, a presença de fungos do gênero Phoma e Candida revela o potencial patogênico desta via de infecção. O gênero Phoma está envolvido em alguns casos de feohifomicoses, micoses subcutâneas causadas por fungos dematiáceos com relatos de infecções em órgãos e sistemas humanos. As estruturas traumatizantes de alguns peixes fluviais apresentam fungos patogênicos e esta pode ser uma importante via de infecção que deve ser considerada em algumas regiões do Brasil, uma vez que há um grande número de pescadores e peixes traumatogênicos.
