RESUMO

BACKGROUND: An increasing number of immediate hypersensitivity reactions (HSR) have been reported after the use of Patent Blue V (PBV) for breast cancer surgery. This is the first study to publish prospective data with systematic allergological assessment. METHODS: We conducted a multicentre study in 10 French cancer centres for over 6 months. All patients scheduled for breast surgery with injection of PBV were included in the study. Patients were screened for past medical history, atopy, and known food and drug allergies. When suspected HSR or unexplained reactions occurred after injection of PBV, blood samples were taken, and plasma histamine and serum tryptase concentrations were measured. HSR to PBV was suggested if skin tests performed 6 weeks later were positive. RESULTS: Nine suspected HSR to PBV were observed in 1742 patients. Skin tests were positive in six patients, giving an incidence of 0.34%. Four grade I and two grade III HSR were observed, both requiring intensive care unit treatment. Mean onset time of the reaction was 55 ± 37 min. Plasma histamine was elevated in four patients, while serum tryptase was normal. We found no risk factors associated with HSR to PBV. CONCLUSION: An incidence rate of one in 300 HSR to PBV was observed for patients exposed to PBV during sentinel lymph node detection. This rate is higher than rates reported after the use of neuromuscular blocking agents, latex or antibiotics.

RESUMO

To study the rate and regulation of alveolar fluid clearance in acute pneumonia, we created a model of Pseudomonas aeruginosa pneumonia in rats. To measure alveolar liquid and protein clearance, we instilled into the airspaces a 5% bovine albumin solution with 1.5 microCi of 125I-human albumin, 24 h after intratracheal instillation of bacteria. The concentration of unlabeled and labeled protein in the distal airspaces over 1 h was used as an index of net alveolar fluid clearance. Since there was histologic evidence of alveolar epithelial injury, several methods were used to measure alveolar fluid clearance, including the use of experiments in rats with blood flow and the use of experiments in rats without blood flow, so that movement across the epithelial barrier would be minimized in the latter group. The results with each method were identical. We found that P. aeruginosa pneumonia increased alveolar liquid clearance over 1 h by 48% in studies with blood flow, and by 43% in rats without blood flow, compared with respective controls (P < 0.05). In both studies, this increase was inhibited with amiloride. However, propranolol had no inhibitory effect, thus ruling out a catecholamine-dependent mechanism to explain the increase in alveolar fluid clearance. An antitumor necrosis factor-alpha neutralizing antibody, instilled into the lung 5 min before bacteria, prevented the increase in alveolar liquid clearance in rats with pneumonia (P < 0.05). Also, TNFalpha (5 microg) instilled in normal rats increased alveolar liquid clearance by 43% over 1 h compared with control rats (P < 0.05). In normal rats instilled with TNFalpha, propranolol had no inhibitory effect. In conclusion, gram-negative pneumonia markedly upregulates net alveolar epithelial fluid clearance, in part by a TNFalpha-dependent mechanism. This finding provides a novel mechanism for the upregulation of alveolar epithelial sodium and fluid transport from the distal airspaces of the lung.

RESUMO

We reported the case of a patient presenting a rectal cancer of the upper part with a BMI at 59 which was previously considered as a contraindication to surgery. To perform the operation we had to make as first step of the procedure a panniculectomy. The technique made possible the rectal resection under good conditions, without blood transfusion. The post-operative course was uneventful except a pulmonary embolism controlled with medical treatment. This procedure is feasible in colorectal surgery.

RESUMO

A study of 51 patients undergoing elective major abdominal surgery was carried out to determine the incidence of postoperative respiratory failure requiring mechanical ventilation for more than 24 h and which preoperative and intraoperative factors are associated with this respiratory complication. Mechanical ventilation for more than 24 h was required in 12 of the 51 patients. These 12 patients had a significantly longer stay in the intensive care unit and in the hospital than the patients who were successfully extubated in the postoperative period. Also, there was a trend for a higher mortality in the ventilated group compared to the group of patients who did not require postoperative ventilation. Preoperative abnormalities in FEV1 did not identify which patients were destined to require postoperative ventilation. Significant differences for the ventilated versus the nonventilated patients included a longer history of cigarette smoking, a lower preoperative PaO2, and a large intraoperative blood loss.

RESUMO

The capacity of the alveolar epithelial barrier to remove excess alveolar fluid from the airspaces of the lung was studied in an experimental model of moderate hyperoxic lung injury. Rats were exposed to 100% oxygen for 40 h in an exposure chamber and compared with control animals exposed to room air. Extravascular lung water was calculated gravimetrically. Alveolar and lung liquid clearance were studied over 1 h by instillation of a 5% albumin solution with 1.5 microCi of 125I-labeled albumin (6 mL/kg into both lungs). The concentration of both the unlabeled and labeled albumin was used to calculate alveolar liquid clearance. Hyperoxic rats developed pulmonary edema, with a 33% increase in extravascular lung water to 5.3 +/- 0.1 g of water per gram of dry lung, compared with 4.0 +/- 0.2 g of water per gram of dry lung in control rats (p < 0.05). This degree of edema was associated with a significant increase in the alveolar-arterial oxygen difference (241 +/- 61 vs 124 +/- 14 mm Hg in control animals exposed to room air, p < 0.05). Despite this moderate degree of lung injury, alveolar fluid clearance was normal (30 +/- 3%) compared with control rats (33 +/- 6%). Furthermore, the hyperoxic injured rats responded normally to an exogenous beta-adrenergic agonist (terbutaline, 10(-4) mol/L) with a 67% increase in the rate of alveolar liquid clearance (50 +/- 5%). Thus, in the setting of moderate hyperoxic lung injury, the alveolar epithelial barrier is still capable of removing fluid at a normal rate and responding to beta-adrenergic agonist treatment. These experimental results have potential clinical implications for patients with acute lung injury.

RESUMO

In a prospective study, patients undergoing abdominal cancer surgery were randomly allocated to receive either general anesthesia with fentanyl intravenously and postoperative analgesia with parenteral morphine (GA group) or general anesthesia combined with epidural bupivacaine and epidural morphine for postoperative pain relief (EP group). Analgesia was tested on a visual pain scale. Pulmonary complications were evaluated by clinical complications, blood gas analysis, x-ray film changes, and pulmonary volumes (vital capacity, forced expiratory volume in 1 second). Measurements were performed on the day before the operation and on the first 5 postoperative days. In the EP group the pain relief was significantly better on the first day (p less than 0.03). Whatever the criteria used, the rates of pulmonary complications were similar in the two groups: clinical complications 21% versus 26%, radiologic complications 50% versus 64% for GA and EP groups, respectively. Postoperative PaO2 and spirometric values were similar in the two groups. Postoperative epidural analgesia may improve the patient's comfort but does not decrease the incidence of pulmonary complications.

RESUMO

The effect of removing pulmonary blood flow on the clearance of excess liquid and protein from the air spaces and interstitium of the normal lung was studied in anesthetized ventilated sheep. To eliminate pulmonary blood flow to one lung, the left pulmonary artery was occluded. Autologous serum (3 ml/kg) with 125I-labeled albumin was then instilled into the left lower lobe. Hemodynamics and lung lymph were measured, and the lungs were removed after 4 h. Alveolar protein concentration over 4 h was used as the index of alveolar liquid clearance. Total lung liquid clearance was measured by the gravimetric method. The percent increase in alveolar protein concentration over baseline was similar between sheep without pulmonary blood flow (33.8 +/- 17.4) and with pulmonary blood flow (31.1 +/- 14.6); thus, alveolar liquid clearance was not changed by the absence of pulmonary blood flow. Also, in the absence of pulmonary blood flow, lung liquid clearance (as percent of instilled) over 4 h was 27.1 +/- 3.8 (n = 7), which was not significantly different from control experiments with pulmonary blood flow (26.4 +/- 7.1, n = 7). In the sheep without pulmonary blood flow, bronchopulmonary anastomotic flow was 41.5 +/- 21.3 ml/min. To further reduce blood flow to the lung, both the left pulmonary artery and the bronchoesophageal artery were occluded, which reduced bronchopulmonary anastomotic flow to the left lung to 12.0 +/- 9.3 ml/min. This further reduction in blood flow did not, however, change alveolar or lung liquid clearance. Even with this low blood flow to the left lung, the removal of 125I-albumin from the lung was not altered.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

The primary objective of these studies was to test the contribution of ventilation and blood flow to the removal of excess liquid from the air spaces and interstitium of the lung. First, after eliminating ventilation by clamping the left main bronchus in anesthetized sheep, alveolar and lung liquid clearance was not altered over 4 h compared with control sheep that were ventilated normally. Thus, removal of excess liquid across the alveolar epithelium was independent of the change in the transalveolar hydrostatic pressure gradient produced by ventilation. Second, to determine the effect of removing all blood flow to the lung, we developed a new in situ sheep lung model in which lung lymph flow was measured over 4 h with or without ventilation after the sheep had been exsanguinated. Alveolar liquid clearance, as measured by the percent increase in alveolar protein concentration over 4 h, was similar between sheep without blood flow (31 +/- 18%) compared with sheep with normal blood flow to the lungs (31 +/- 17%). Lung lymph flow contributed to only 10-15% of the clearance of the excess alveolar liquid that was transported to the interstitium, indicating that nonlymphatic pathways accounted for most of the excess lung liquid clearance in the absence of microvascular filtration. Third, because ouabain completely inhibited alveolar liquid clearance in this in situ sheep lung model, these data provide evidence that alveolar liquid clearance depends on an intact Na(+)-K(+)-ATPase-dependent pump mechanisms. Finally, this in situ model represents a unique experimental preparation that can be used to study the alveolar epithelial barrier without blood flow or ventilation for a short time (4 h) interval.

RESUMO

Alveolar and lung liquid clearance were studied over 8 h in intact anesthetized ventilated rabbits by instillation of either isosmolar Ringer lactate (2 ml/kg) or autologous plasma (2 or 3 ml/kg) into one lower lobe. The half time for lung liquid clearance of the isosmolar Ringer lactate was 3.3 h and that for plasma clearance was 6 h. In the plasma experiments, the alveolar protein concentration after 1 h was 5.2 +/- 0.8 g/dl, which was significantly greater than the initial instilled protein concentration of 4.3 +/- 0.7 g/dl (P less than 0.05). Thus alveolar protein concentration increased by 21 +/- 12% over 1 h, which matched clearance from the entire lung of 19 +/- 11% of the instilled volume. Overall the rate of alveolar and lung liquid clearance in rabbits was significantly faster than in prior studies in dogs and sheep. The fast alveolar liquid clearance rate in rabbits was not due to higher endogenous catecholamine release, because intravenous and alveolar (5 x 10(-5) M) propranolol did not slow the clearance. Also, beta-adrenergic therapy with alveolar terbutaline (10(-5) or 10(-4) M) did not increase the alveolar or lung liquid clearance rates. Phloridzin (10(-3) M) did not slow alveolar liquid clearance. However, amiloride (10(-4) M) inhibited 75% of the basal alveolar liquid clearance in rabbits, thus providing evidence that alveolar liquid clearance in rabbits depends primarily on sodium-dependent transport. This rabbit study provides further evidence for important species differences in the basal rates of alveolar liquid and solute clearance as well as the response to beta-adrenergic agonists and ion transport inhibitors.

RESUMO

Alveolar and lung liquid clearances were studied over 1, 4, and 6 h in intact anesthetized ventilated rats by instillation of 5% albumin solution with 1.5 microCi of 125I-labeled albumin (3 ml/kg into 1 lung or 6 ml/kg into both lungs). Alveolar protein clearance as measured by residual 125I-albumin in the lung over 6 h was similar to the slow rates measured in other species. Alveolar liquid clearance was estimated by the concentration of albumin in the air spaces. After 1 h, this concentration was 7.8 +/- 0.7 g/dl, which was significantly greater than the initial protein concentration of 5.3 +/- 0.2 g/dl (P < 0.05). Amiloride (10(-3) M) inhibited 45% of the basal alveolar liquid clearance, and ouabain (10(-3) M), instilled and intravenously infused (0.004 mg), inhibited 30% of the clearance. beta-Adrenergic agonist instillation increased alveolar liquid clearance to the fastest 1-h rate (48 +/- 3% of instilled volume) that we observed in any intact species. The removal of the instilled fluid from the lung (expressed as lung liquid clearance; 0.96 +/- 0.3 ml/h) was twice as fast as the rate of alveolar and lung liquid clearance reported in the isolated or in situ rat lung models. The rate of alveolar and lung liquid clearance in these intact rats was significantly faster than those in prior studies in dogs and sheep and was similar to the rates in rabbits.

RESUMO

Although keratinocyte growth factor (KGF) protects against experimental acute lung injury, the mechanisms for the protective effect are incompletely understood. Therefore, the time-dependent effects of KGF on alveolar epithelial fluid transport were studied in rats 48-240 h after intratracheal administration of KGF (5 mg/kg). There was a marked proliferative response to KGF, measured both by in vivo bromodeoxyuridine staining and by staining with an antibody to a type II cell antigen. In controls, alveolar liquid clearance (ALC) was 23 +/- 3%/h. After KGF pretreatment, ALC was significantly increased to 30 +/- 2%/h at 48 h, to 39 +/- 2%/h at 72 h, and to 36 +/- 3%/h at 120 h compared with controls (P < 0.05). By 240 h, ALC had returned to near-control levels (26 +/- 2%/h). The increase in ALC was explained primarily by the proliferation of alveolar type II cells, since there was a good correlation between the number of alveolar type II cells and the increase in ALC (r = 0.92, P = 0.02). The fraction of ALC inhibited by amiloride was similar in control rats (33%) as in 72-h KGF-pretreated rats (38%), indicating that there was probably no major change in the apical pathways for Na uptake in the KGF-pretreated rats at this time point. However, more rapid ALC at 120 h, compared with 48 h after KGF treatment, may be explained by greater maturation of alpha-epithelial Na channel, since its expression was greater at 120 than at 48 h, whereas the number of type II cells was the same at these two time points. beta-Adrenergic stimulation with terbutaline 72 h after KGF pretreatment further increased ALC to 50 +/- 7%/h (P < 0.5). In summary, KGF induced a sustained increase over 120 h in the fluid transport capacity of the alveolar epithelium. This impressive upregulation in fluid transport was further enhanced with beta-adrenergic agonist therapy, thus providing evidence that two different treatments can simultaneously increase the fluid transport capacity of the alveolar epithelium.

RESUMO

Under some pathological conditions, ion transport across alveolar epithelial cells is downregulated, whereas under other pathological conditions, it may be upregulated. Because endotoxin is a biologically relevant pathological stimulus, we investigated the effect of endotoxin on alveolar epithelial liquid clearance in vivo. Escherichia coli endotoxin (220 micrograms/kg) was instilled into the lungs via the trachea of rats. Then, 24 or 40 h after endotoxin instillation, alveolar and lung liquid clearances were studied over 1 h by instillation of a 5% albumin solution with 1.5 microCi of 125I-labeled albumin (6 ml/kg into both lungs). Alveolar liquid clearance was significantly greater at 24 h (36 +/- 5%) and 40 h (38 +/- 7%) after endotoxin exposure than in saline-instilled controls (27 +/- 6%). Although there was an influx of neutrophils into the air space, there was no increase in lung epithelial permeability to protein at 24 or 40 h. Amiloride (2 x 10(-3) M), a sodium channel inhibitor, significantly reduced alveolar liquid clearance in the rats exposed to endotoxin. However, the increase in alveolar liquid clearance was not inhibited when propranolol (2 x 10(-5) M) was added to the 5% albumin solution. Thus exposure to alveolar endotoxin upregulates net alveolar fluid clearance in vivo for up to 40 h, a potentially important mechanism for accelerating alveolar fluid clearance under some pathological conditions. The increase in alveolar liquid clearance 24 and 40 h after instillation of endotoxin into the air spaces is mediated by an increased uptake of sodium through amiloride-sensitive sodium channels.

RESUMO

Physiological responses to postoperative acute pain may impede organ functions (cardiovascular, pulmonary, coagulation, endocrine, gastrointestinal, central nervous system, etc). Pain alleviation improves patient's comfort, but also may minimise perioperative stress response, physiological responses and postoperative organ dysfunction, assist postoperative nursing and physiotherapy, enhance clinical outcome, and potentially shorten the hospital stay. Potent postoperative analgesia, especially by epidural route, may be associated with reduction in incidence and severity of many perioperative dysfunctions. Peridural analgesia using local anaesthetics is the best technique for decreasing postoperative stress after lower abdominal or lower limb surgery. Analgesia using either epidural or high doses of morphine may improve some cardiac variables such as tachycardia and ischaemia, but does not change the incidence of severe cardiac complications. For patients undergoing vascular or orthopaedic surgery, epidural analgesia can improve clinical outcome by preventing the development of arterial or venous thromboembolic complications. However, in comparative studies, the control groups did not receive adequate prophylactic treatment for thromboembolic complications. Epidural analgesia can hasten the return of gastrointestinal motility and shorten the hospital stay. Postoperative mental dysfunction is decreased using intravenous PCA morphine in the elderly. Epidural analgesia with local anaesthetics improves postoperative respiratory function but, for unknown reasons, these benefits are not associated with a decrease in respiratory complications. On balance, the mode of acute pain relief decreases adverse physiological responses and many intermediate outcome variables; however, there is inconclusive evidence that it affects clinical outcome. Major advances in postoperative recovery can be achieved by early aggressive perioperative care, including potent analgesia, early mobilisation and oral nutrition. As a result, the hospital stay may be shortened.

RESUMO

A case is reported of rupture of the trachea following endotracheal intubation for general anaesthesia. A continuous flow oxygen was used to inflate the cuff, which was thought to be pierced and so responsible for a ventilation leak. This technique had already been successfully used by the authors in cases of leaking cuffed tubes in patients on long-term artificial ventilation. However, this technique appeared to be dangerous in the case described.

RESUMO

Abdominal surgery, especially upper abdominal surgical procedures are known to adversely affect pulmonary function. Pulmonary complications are the most frequent cause of postoperative morbidity and mortality. This review article aimed to analyse the incidence and risk factors for postoperative pulmonary morbidity and their prevention. The most important means for preoperative assessment is the clinical examination; pulmonary function tests (spirometry) are not reliably predictive for postoperative pulmonary complications. Age, type of surgical procedure, smoking and nutritional state have all been identified as potential predictors for postoperative complications. However, usually there is not enough preoperative time available to obtain beneficial effects of stopping smoking and improvement of nutritional state. In patients with COPD, a preoperative multidisciplinary evaluation including the primary care physician, pulmonologist/intensivist, anesthesiologist and surgeon is required. Consensus as to preoperative physiologic state, therapeutic preparation, and postoperative management is essential. Simple spirometry and arterial blood gas analysis are indicated in patients exhibiting symptoms of obstructive airway disease. There are no values that contra-indicate an essential surgical procedure. Smoking should stop at least 8 weeks preoperatively. Preoperative therapy for elective surgery with antibiotics, beta2-agonist, or anticholinergic bronchodilator aerosols, as well as training in cough and lung expansion techniques should begin at least 24 to 48 hours preoperatively. Postoperative therapy should be continued for 3 to 5 days. Usually, anaesthesia is responsible for early complications, whereas surgical procedures are often associated with delayed morbidity. Laparoscopic procedures are recommended, as postoperative morbidity and hospital stay seem reduced in patients without COPD. Regional anaesthesia is given as having less adverse effects on pulmonary function than general anaesthesia. However, for unknown reasons these benefits are not associated with a decrease in postoperative respiratory complications. Moreover, the quality or the type of postoperative analgesia does not influence postoperative respiratory morbidity. Postoperatively, oxygen administration increases SaO2, but cannot abolish desaturation due to obstructive apnea. The various techniques of physiotherapy (chest physiotherapy, incentive spirometry, continuous positive airway pressure breathing) seem to be equivalent in efficacy; but intermittent positive pressure breathing has no advantages, compared with the other treatments and could even be deleterious. Chest physiotherapy and incentive spirometry are the most practical methods available for decreasing secretion contents of airways, whereas continuous positive airway pressure breathing is efficient on atelectasis. In stage II or III COPD patients, admission in a intensive therapy unit and prolonged mechanical ventilation may be required.

RESUMO

Case report of an obese patient who suffered a bilateral rhabdomyolysis after major abdominal surgery under general anaesthesia combined with thoracic epidural analgesia. The patient was in the lithotomy position during the ten hours time period of the surgery. As the patient was sedated in the intensive care unit, the diagnosis was made more difficult. Clinical signs consisted of pain, oedema and neurosensitive deficit in both legs. Creatinine kinase plasma concentration was increased. Treatment included fluid infusions and fasciotomy. The sequelae were major and consisted mainly in muscular deficiency of both legs. This complication is favoured by prolonged surgery and muscular compression elicited by non physiological positions.

RESUMO

Pulmonary complications are frequent after abdominal surgery. The object of this study was to evaluate the incidence and the predisposing factors of the postoperative pulmonary complications with a particular attention to their definitions. It included 146 patients. The respiratory complications were separated into clinical complications (bronchitis), radiological complications (atelectasis) and hypoxaemia (PaO2 less than 70 mmHg). Clinical complications (23%) were correlated neither with radiological complications (57%) nor hypoxaemia (46%). They particularly occurred in patients with a preoperative history of respiratory disease. Preoperative risk factors were males, low PaO2 and decreased FEV1. Radiological complications were strongly correlated with postoperative hypoxaemia. Their incidence was not affected by a previous history of respiratory disease. Both radiological complications and hypoxaemia were predicted by age.

RESUMO

The analgesic and antipyretic efficacy of propacetamol is identical to paracetamol. Because the propacetamol is injectable and its side effects are uncommon and mild, it is the drug commonly used in France for postoperative pain relief. The aim of this prospective study was to compare the analgesic efficacy of propacetamol after breast surgery or thyroidectomy when it was administered either systematically or on the patients demand. After informed consent, 119 patients having undergone breast surgery or thyroidectomy, having received the same general anaesthesia and scheduled for receiving propacetamol postoperatively, were included in the study. Two groups of patients were compared, those who received propacetamol on demand (D Group) and those who received propacetamol systematically (S Group). During the first 24 hours, analgesia was evaluated on a visual analogical scale graded from 0 to 100 mm, at rest and during mobilization; the efficacy was also evaluated by the amount of additional analgesic drug injected. Side effects were also compared between the 2 treatment groups. In the 2 groups, demographic data, type of anaesthesia and type of surgery were identical. Postoperative pain relief and supplemental injection of morphine were not statistically different between the 2 groups. Propacetamol doses were statistically higher in the S group than in the D group (7.8 +/- 0.7 g and 3.9 +/- 2.3 g respectively, p < 0.05). Pain during propacetamol infusion was more frequent in the D group than in the S group (30% and 13% respectively, p < 0.05). No other adverse effects were observed during the study. Propacetamol alone is sufficient for pain relief after peripheral surgery; more than 90% of patients need no supplemental analgesic, and adverse effects are rare.

RESUMO

BACKGROUND: Retrospective studies have suggested that regional analgesia combined with general anaesthesia could decrease cancer recurrence. The purpose of this study was to assess the influence of regional analgesia on recurrence-free (RFS) and overall survival in patients undergoing major intra-abdominal surgery for cancer. METHOD: Patients previously included in a prospective randomized study comparing two postoperative techniques of analgesia were retrospectively studied. The EP group received general anaesthesia with bupivacaine thoracic epidural analgesia and the SC group received general anaesthesia with fentanyl followed by continuous subcutaneous morphine. RESULTS: One hundred and thirty-two patients were analyzed (63 and 69 in SC and EP group, respectively) with a 17-year-median follow-up. After 5 years, RFS was 43% [95% CI: 32%-55%] in EP group and 24% [95% CI: 15%-36%] in SC group, but the difference did not reach statistical significance for RFS nor for overall survival (P=0.10 and 0.16 respectively). Using multivariable analysis over the whole follow-up period, the type of analgesia was not a statistically significant predictive factor for RFS (EP/SC, HR=1.3 [95% CI: 0.8-2.0%]). The anaesthesia effect changed moderately over the follow-up and HR for overall survival (EP/SC) reached statistical significance after 5, 6 and 8 years. CONCLUSION: Despite a trend in favour of the epidural, this retrospective review of patients included in a previous randomized study failed to demonstrate a statistically significant association between the perioperative analgesia and RFS after abdominal surgery for cancer. The duration of follow-up may have an impact on the analgesia effect on survival.
