RESUMO
BACKGROUND: We aimed to determine the incidence of surgical site infection (SSI) after cesarean delivery (CD) and identify the risk factors in a rural population. METHODS: We identified 218 SSI patients by International Classification of Disease codes and matched them with 3131 parturients (control) from the electronic record database in a time-matched retrospective quality assurance analysis. RESULTS AND DISCUSSION: The incidence of SSI after CD was 7.0 %. Risk factors included higher body mass index (BMI) [40.30 ± 10.60 kg/m2 SSI (95 % CI 38.73-41.87) vs 34.05 ± 8.24 kg/m2 control (95 % CI 33.75-34.35, P < 0.001)], years of education [13.28 ± 2.44 years SSI (95 % CI 12.9-13.66) vs 14.07 ± 2.81 years control (95 % CI 13.96-14.18, P < 0.001)], number of prior births [2 (1-9) SSI vs 1 (1-11) control (P < 0.001)], tobacco use (OR 1.49; 95 % CI 1.06-2.09, P = 0.03), prior diagnosis of hypertension (OR 1.80; 95 % CI 1.34-2.42, P < 0.001), gestational diabetes (OR 1.59; 95 % CI 1.18-2.13, P = 0.003), and an emergency/STAT CD (OR 1.6; 95 % CI 1.1-2.3, P = 0.01). CONCLUSIONS: Risk factors for SSI after CD included higher BMI, less years of education, higher prior births, tobacco use, prior diagnosis of hypertension, gestational diabetes, and emergency/STAT CD. The presence of ruptured membranes was protective against SSI.

The study aimed to identify the risk factors for respiratory failure after surgery. Postoperative respiratory failure (PRF) was defined as prolonged intubation after surgery or reintubation after unsuccessful extubation. We conducted a retrospective analysis of the following risk factors: age, obesity as reflected by body mass index (BMI), gender, patient admitted to hospital (in-patient status) vs. outpatient surgery, smoking, hypertension, chronic obstructive pulmonary disease (COPD), diabetes, abnormal liver function, anaemia, respiratory infection, physical condition as reflected by ASA class, case type (elective or emergency), anaesthesia type, and surgical duration. The incidence of PRF was found to be 2.4%. Independent risk factors were older age, inpatient status, hypertension, COPD, elective procedure, surgical duration >2 hours, and ASA class ≥3. The study concludes that PRF results in significant postoperative complications. Minimising these risks is essential in improving PRF and subsequently surgical outcomes.

Pheochromocytomas are rare tumors that produce excessive epinephrine and norepinephrine, leading to multiple manifestations of catecholamine surges. Acute intraoperative hypertension during pheochromocytoma resection requires prompt control to avoid major and potentially lethal cardiac and neurologic complications. This article reports the planned and successful use of clevidipine (Cleviprex) as the "sole agent" for intraoperative blood pressure management in 2 adult patients with a diagnosis of pheochromocytoma undergoing elective open adrenalectomy. Clevidipine effectively and promptly provided predictable blood pressure control in both patients.
RESUMO
INTRODUCTION: Unintentional dural puncture (UDP) and postdural puncture headache (PDPH) occur during the course of epidural catheter placement for labor analgesia with a reported incidence of 1%-5%. After UDP with an epidural needle, 80%-86% of patients develop PDPH. Acute symptoms after UDP are well known. However, few studies have evaluated the long-term complications of UDP, which is important in assisting parturients in the decision-making informed consent process. We sought to elucidate the long-term (>6 weeks) sequelae of PDPH by examining parturients who had UDP (both recognized and unrecognized) associated with labor epidural analgesia. METHODS: Parturients with a documented UDP (n = 308) over a 5-year period were followed up for acute and long-term residual symptoms (lasting >6 weeks) and compared with a control group (no documented UDP, n = 50) in the same period. Specific symptoms included headache, backache, neck ache, auditory symptoms, and visual symptoms. RESULTS: In comparing parturients with a UDP with control group (no UDP), differences were noted in overall acute symptoms (75.9% vs 21.7%, P < .001), specifically headache (87.0% vs 8.7%, P < .001), backache (47.2% vs 19.6%, P = .002), neck ache (30.1% vs 2.2%, P < .001), auditory (13.8% vs 0%, P = .02), and visual symptoms (19.5% vs 0%, P = .002). Differences were also noted in comparing chronic symptoms (26.5% vs 10.9%, P = .04) and specifically with respect to chronic headache (34.9% vs 2.2%, P < .001), backache (58.1% vs 4.4%, P < .001), and neck ache (14.0% vs 0%, P = .02). No differences were noted between groups in comparing chronic auditory and visual symptoms. CONCLUSION: Chronic headache and backache sequelae persist in the obstetrical population after UDP. When parturients are considering labor epidural analgesia, long-term sequelae should be discussed in the informed consent decision-making process.

UNLABELLED: Given in clinically relevant large doses to rats, mu-opioids produce limbic system hypermetabolism and histopathology. This investigation extends these observations, in both rats and humans, for the short-acting drug remifentanil, which allows more precise control and assessment of the effects of duration of opioid exposure. We performed two series of experiments: one in rats for neuropathologic effects and the second in humans for neurometabolic effects. Fifty mechanically ventilated rats received saline solution or remifentanil 20-160 microg x kg(-1) x min(-1) for 3 h, followed by neuropathologic evaluation 7 days later. Four volunteers underwent induction of anesthesia and endotracheal intubation with propofol and rocuronium administration followed by remifentanil infusion at 1-3 microg x kg(-1) x min(-1) with positron emission tomography evaluation of cerebral metabolic rate for glucose. In rats, dose-related electroencephalogram activation was evident and 19 of 40 remifentanil-treated rats showed brain damage, primarily in the limbic system (P < 0.01). In humans, cerebral metabolic rate for glucose in the temporal lobe increased from 6.29 +/- 0.32 to 7.68 +/- 1.05 mg x 100 g(-1) x min(-1) (P < 0.05). These data indicate that prolonged large-dose remifentanil infusion is neurotoxic in rats with congruent metabolic effects with brief infusion in humans and suggest that some adverse effects reported in rats may be clinically relevant. IMPLICATIONS: This study demonstrates dose-related remifentanil neurotoxicity in physiologically controlled rats with congruent brain metabolic effects in four humans undergoing positron emission tomography evaluation during brief large-dose remifentanil anesthesia. These data suggest that some adverse effects reported in rats may be clinically relevant.
