Validation of mid-infrared spectroscopy for macronutrient analysis of human milk.

OBJECTIVE: Human milk has considerable variation in its composition. Hence, the nutrient profile is only an estimate and can result in under- or over-estimation of the intake of preterm infants. Mid-infrared (MIR) spectroscopy is an evolving technique for analyzing human milk but needs validation before use in clinical practice. STUDY DESIGN: Human milk samples from 35 mothers delivering at 35 weeks to term gestation were analyzed for macronutrients by MIR spectroscopy and by standard laboratory methods using Kjeldahl assay for protein, Mojonnier assay for fat and high-pressure liquid chromatography assay for lactose. RESULTS: MIR analysis of the macronutrients in human milk correlated well with standard laboratory tests with intraclass correlation coefficients of 0.997 for fat, 0.839 for protein and 0.776 for lactose. Agreement between the two methods was excellent for fat, and moderate for protein and lactose (P<0.001). CONCLUSIONS: This methodological paper provides evidence that MIR spectroscopy can be used to analyze macronutrient composition of human milk. Agreement between the methodologies varies by macronutrient.

Use of tegaserod along with polyethylene glycol electrolyte solution for colonoscopy bowel preparation: a prospective, randomized, double-blind, placebo-controlled study.

BACKGROUND: Polyethylene glycol electrolyte solution (PEG-EL) used for colonoscopy preparation is not well tolerated by several patients. A significant number of patients have inadequate bowel preparation despite taking PEG-EL. AIMS: To determine the effect of prokinetic agent, tegaserod when given in addition to PEG-EL on patient tolerance, quality of colonic preparation and adverse side effects experienced. METHODS: In this prospective, randomized, placebo-controlled, double-blind study, a total of 130 patients scheduled for colonoscopy were enrolled. They were instructed to take three pills of either tegaserod 6 mg each or placebo (one pill twice on the day prior to and third pill in the morning on the day of colonoscopy) in addition to standard 4L of PEG-EL in the evening prior to the day of colonoscopy. Patient tolerance of preparation, quality of bowel preparation, overall satisfaction and adverse side effects were compared between the two groups. RESULTS: Fifty-five patients in placebo group and 58 patients in tegaserod group completed the study. There was no difference between the two groups in the tolerance of preparation, quality of bowel preparation, overall satisfaction and the side effects. CONCLUSION: Addition of tegaserod to polyethylene glycol electrolyte solution during colonoscopy preparation does not improve patient tolerance, quality of colonic preparation or the adverse side effects.

Diagnosis of gestational diabetes in early pregnancy.

OBJECTIVE: To determine whether glucose intolerance can be identified early in gestation in a high-risk population so that early intervention can be planned to prevent associated morbidity. RESEARCH DESIGN AND METHODS: After appropriate dietary preparation, patients with a high risk for gestational diabetes underwent a 50-g oral glucose screening test during fasting. Patients were tested on enrollment and every 10 wk until delivery. Those with a 1-h plasma glucose value of greater than or equal to 7.5 mM underwent a 100-g oral glucose tolerance test. Gestational diabetes was based on either a markedly abnormal 50-g screening test or abnormal 100-g oral glucose tolerance test. RESULTS: Ten of 15 (66%) patients who developed gestational diabetes were diagnosed during the first half of the pregnancy. Six were diagnosed in the first trimester. If the definition of an abnormal 1-h plasma glucose value was lowered from 7.5 to 7.2 mM, an additional 2 patients could have been identified in the first trimester with an improvement in sensitivity from 70 to 91% with only a slight drop in specificity (from 91 to 88%). Diagnosis of gestational diabetes was not enhanced by measuring plasma insulin concentrations or insulin-glucose molar ratios. CONCLUSIONS: The diagnosis of gestational diabetes in a high-risk population can be made in the first half of pregnancy. Early diagnosis should permit evaluation of intervention strategies, which may result in improved perinatal outcome.

Estimation of total body water in very-low-birth-weight infants by using anthropometry with and without bioelectrical impedance and H2[(18)O].

The usefulness of bioelectrical impedance (BI) with anthropometry to measure total body water (TBW) was evaluated in very-low-birth-weight (VLBW) infants. A specific regression equation to measure TBW in a VLBW population was developed by simultaneously using the H2[(18)O] dilution method and BI in 12 infants with a gestational age of 24-30 wk and weighing <1200 g at birth. After an oral dose of H2[(18)O], the tracer dilution was measured in expired carbon dioxide. BI measurements were made with a model BIA-101 apparatus (RJL Systems, Detroit). Electrodes were placed in the standard position as well as proximally on the leg and the forearm. The best correlation was observed between body weight and TBW (r = 0.989). For BI, the best correlation was obtained when gestational age was used as a covariable along with body weight and crown-heel length (r = 0.985). The correlation was comparable with proximal electrode placement (r = 0.985). The new correlation was evaluated in 6 infants weighing < 1008 g. A significant correlation between BI and H2[(18)O]-measured TBW was observed (r = 0.988). Published regression equations for infants consistently gave higher estimates of TBW in another group of 14 infants weighing <1200 g than did the new correlations. TBW represented 84-95% of body weight in these VLBW infants. TBW could be computed simply from body weight alone. Use of BI and length as covariables did not add significantly to the estimate of TBW in VLBW infants.

Heart rate variability in cocaine-exposed newborn infants.

BACKGROUND: Infants born to cocaine-using mothers have a 3- to 8-fold increase in sudden infant death syndrome. Its underlying cause, in part, may be attributed to abnormal autonomic function. We proposed to study heart rate variability, reflecting autonomic control of the heart, in cocaine-exposed infants. METHODS: From 1997 to 2000, we studied 217 asymptomatic, term infants, of whom 68 had intrauterine cocaine exposure (group I). Their data were compared with infants exposed to drugs other than cocaine (group II, n = 77) and no drugs (group III, n = 72). Twenty-four-hour heart rate variability was measured within 72 hours of birth. RESULTS: Cocaine-exposed infants, as compared with the 2 control groups, had an overall significant decrease (P <.05) in global heart rate variability and a lower standard deviation of all valid N-N intervals in the recording (41.9 +/- 1.4 ms vs 47.6 +/- 1.3 ms and 46.9 +/- 1.3 ms, respectively). Vagal parameters such as high-frequency power and the square root of the mean of the squared differences between adjacent N-N intervals were also lower in newborns with heavy in utero cocaine exposure. CONCLUSIONS: Decreased heart rate variability was seen in cocaine-exposed infants. Whether low heart rate variability is a marker for increased risk of sudden death in infants (as it is in adults with structural heart disease) is unknown and requires further investigation.

Short-term efficacy of oral dimercaptosuccinic acid in children with low to moderate lead intoxication.

OBJECTIVE: To determine the short-term efficacy of meso-2,3-dimercaptosuccinic acid (DMSA) in mild to moderately lead poisoned children. METHODS: Medical records of all pediatric patients receiving 19 days of DMSA between June 1991 and May 1993 were reviewed retrospectively. Patients were included if their pretreatment blood lead concentration (BPb) was 1.21 to 2.36 mumol/L (25 to 49 micrograms/dL) and excluded if they: received DMSA through participation in a pharmaceutical company-sponsored drug study; underwent chelation therapy in the previous 28 days; or received another chelating agent concomitantly with DMSA; or if noncompliance was documented. Homes were inspected and abated of major hazards before chelation therapy. BPb and blood zinc protoporphyrin concentration (ZnP) were obtained at baseline. DMSA was administered in a dose approximating 10 mg/kg per dose every 8 hours for 5 days, followed by 10 mg/kg per dose every 12 hours for 14 days. Baseline laboratory studies were repeated weekly while the patients were receiving therapy and for 2 weeks after therapy, then monthly unless chelated again. RESULTS: Of the 46 children who were treated with DMSA, 18 were excluded from the analysis. In the remaining 28 children, the mean +/- SD pretreatment BPb and ZnP were 1.79 +/- 0.33 mumol/L (37 +/- 6.9 micrograms/dL) and 1.26 +/- 0.64 mumol/L (71 +/- 36.1 micrograms/dL), respectively. The percent reduction (mean +/- SD) in BPb compared with baseline was -43% +/- 20.8%, -26% +/- 16.9%, and -31% +/- 20.2% on mean days 18, 30, and 80, respectively, whereas the changes in ZnP were -12% +/- 21.7%, -20% +/- 18.1%, and -31% +/- 21.9%, respectively. Eighty percent of patients had 20% or more reduction in their pretreatment BPb and/or ZnP after completion of DMSA therapy (95% confidence interval, 61, 92%). No significant adverse effects were observed except for neutropenia (absolute neutrophil count of 0.752 x 10(9)/L) in one patient. CONCLUSION: Our findings support the short-term efficacy of DMSA in children with BPb of 2.36 mumol/L (49 micrograms/dL) or less.

Impact of race and gestational age on red blood cell indices in very low birth weight infants.

BACKGROUND: Normative data for hematologic values in the very low birth weight infants are limited and inconsistent, with the reported mean hematocrit (HCT) in these infants ranging from 43.5% to 60%. No data are available on the effect of race. OBJECTIVES: To establish normative data for hemoglobin (Hb) and HCT by arterial sampling obtained during the first 3 hours after birth in black and white premature infants

Rapid detection of respiratory syncytial virus by a biotin-enhanced immunoassay: test performance by laboratory technologists and housestaff.

A biotin-enhanced enzyme immunoassay (EIA) for respiratory syncytial virus (RSV) antigen detection (TESTPACK RSV) was prospectively compared with virus isolation in cell culture and immunofluorescence. Of 156 nasopharyngeal swab specimens from infants with respiratory symptoms, 81 (52%) yielded RSV in culture. Compared with culture the sensitivity of the EIA was 95% and specificity was 92%; the specificity increased to 97% with a blocking assay. Compared with immunofluorescence the sensitivity of EIA was 92% and specificity was 93%. In order to assess the performance of TESTPACK RSV as a bedside test, nasopharyngeal swabs from 49 children were tested by EIA at the bedside by housestaff and by immunofluorescence in the laboratory; the sensitivity of the EIA was lower (78%) while specificity remained high (95%). Inclusion of older children may have resulted in diminished sensitivity. The TESTPACK RSV is a simple, rapid test that performs well and is easily adaptable to an office setting. Further evaluation of the test in older children may be required.

Weekly telephone contact does not enhance the compliance of home apnea monitoring.

OBJECTIVE: To evaluate the effect of weekly telephone contact with families in enhancing the use of home apnea monitors. STUDY DESIGN: This was a prospective, randomized, single-blinded study of 65 infants who were prescribed home apnea monitoring at the time of initial discharge from the hospital. Exclusion criteria included participation in any other study involving home monitoring or nonavailability of home telephone. Infants were randomized either to the "standard" or "telephone" group by a stratified balanced block technique. All families were instructed to use the monitor during the first 4-week period at all times except during bathing and during the second 4-week period at all unattended times and at night. The families in the telephone group were contacted weekly for 8 weeks. The telephone interview reviewed the events of the previous week but did not include specific encouragement to use the monitor. Both groups received routine pediatric care and follow-up at our high-risk premature clinic. The primary outcome measure was compliance measured as the percentage of time as well as the hours per day that the infant spent on the monitor as recorded by the documented monitor. RESULTS: The telephone (n = 30) and standard (n = 32) groups were similar (p > 0.10) with respect to birth weight (1567 +/- 778 versus 1710 +/- 777 gm), gestational age (30.9 +/- 4.2 versus 31.1 +/- 4.6 weeks), maternal age (24.9 +/- 6.0 versus 25.3 +/- 5.4 years), and commercial insurance (46.7% versus 46.9%), a marker of higher socioeconomic status. Compliance of the telephone versus the standard group was similar during the first 4-week period (74.7 +/- 24.9 versus 75 +/- 27.8%, p = 0.85) (17.9 +/- 5.9 versus 18.2 +/- 6.6 hours/day), the second 4 week period (63.4 +/- 29.1 versus 58.9 +/- 30.9%, p = 0.59) (15.2 +/- 7.0 versus 14.1 +/- 7.4 hours/day) and the entire 8-week period (69.3 +/- 24.7 versus 67.7 +/- 26.2%, p = 0.82, Mann-Whitney U-test) (16.7 +/- 6.0 versus 16.1 +/- 6.5 hours/day), respectively. An abnormal pneumocardiogram at the time of discharge was the only identified factor that improved the compliance for the entire 8-week period (73.1 +/- 22 versus 52.1 +/- 28.5%, p = 0.02) (17.5 +/- 5.2 versus 12.5 +/- 6.8 hours/day) and the first 4-week period of monitoring (81.7 +/- 22.9 versus 59.5 +/- 31.3%, p = 0.01) (19.6 +/- 5.5 versus 14.2 +/- 7.5 hours/day). CONCLUSION: Weekly telephone contact, without specific encouragement to use the monitor, did not improve compliance. Compliance was greater in subjects who had abnormal pneumocardiogram results at the time of discharge from hospital regardless of their telephone/standard group assignment. We speculate that in this already compliant population, more targeted advice is necessary to increase compliance.

Airway pressure release ventilation with a short release time in a child with acute respiratory distress syndrome.

Airway pressure release ventilation (APRV) allows ventilation and oxygenation to occur at lower peak and mean airway pressures than conventional positive pressure ventilation. The use of APRV in adults is an effective method of ventilation for patients with acute lung injury and acute respiratory distress syndrome. However, the use of APRV in children is less established. We report the use of APRV with a short release time of 0.2 s in a child with acute respiratory distress syndrome secondary to respiratory syncytial virus pneumonia.

The effect of music-based imagery and musical alternate engagement on the burn debridement process.

Management of pain is a primary concern in the treatment of burn patients. The intent of this study was to test the efficacy of music-based imagery and musical alternate engagement in assisting burn patients in managing their pain and anxiety during debridement. Twenty-five patients, 7 years of age and older, who were admitted to the Comprehensive Burn Care Center were enrolled in the study, which used a repeated-measures design with subjects serving as their own control. Subjects were randomly assigned to 1 of 2 groups. Those placed in Group A received music therapy intervention during their first dressing change, and no music therapy on the following day. Group B received no music therapy intervention during their first dressing change and music therapy during their next dressing, on the following day. Data were collected at 4 intervals in the medical procedure; in the patient's room before transfer to the treatment room, in the treatment room during debridement, in the treatment room after debridement, and upon returning to the patient's room. The measurements taken were pulse, patients' self-report of pain, patients' self-report of anxiety, and the nurse's observation of patients' tension. There was a significant reduction in the self-reporting of pain in those who received music therapy in contrast to those who did not receive music therapy (P < .03). Music therapy is a valuable noninvasive intervention for the treatment of pain after burn injury.

An analysis of waiting times in a pediatric emergency department.

Waiting times in a pediatric emergency department were studied using direct observations of patients and health providers on 14 separate days. The mean waiting time (from entry to first physician contact) of the 216 children studied was 49 minutes. Time spent in the waiting room was increased by both the nonavailability of a nurse and the nonavailability of an examining room, and was decreased by the severity of the patient's illness. Time spent in the examination room waiting for the physician was related to the availability of the physician and the number of patients concurrently registered in the emergency department as well as the severity of their complaint. Recommendations for decreasing waiting time, based on the observations, are made. Although each setting is unique, the study provides a model for the analysis of waiting patterns in similar facilities.

An investigation of epidemiologic factors associated with large nodular goiter.

BACKGROUND: Sporadic nodular goiter is a common problem in the United States and significant compressive symptoms may occur with progression to a critical size. METHODS: Potential epidemiological variables associated with the development of large unilateral (> or = 50 g) and bilateral (> or = 100 g) nodular goiter were investigated including: age, gender, race, body mass index (BMI), family history of thyroid disease, pregnancy at time of diagnosis, insurance status, and tobacco or alcohol use. Data were obtained from an IRB-approved thyroid database and retrospective chart review of consecutive patients operated on for nodular goiter from 1990 through 2005. A univariate and multivariate analysis of epidemiological variables in patients with "large" versus "small" nodular goiter was completed. RESULTS: Of the 488 patients operated on for nodular goiter, 113 (23%) were classified as "large," 43 with unilateral (mean 106 +/- 72 g) and 70 with bilateral enlargement (mean 173 +/- 92 g) and 375 (77%) were classified as "small," 179 with unilateral (18 +/- 10 g) and 196 with bilateral (37 +/- 24 g) enlargement. Based on univariate analysis, African-American race, age > or = 40 years, BMI > or = 30 kg/m2, and lack of insurance were associated with an increased risk of large nodular goiter (P < or = 0.001), whereas alcohol use was protective (P = 0.002). A multivariate analysis revealed that African-American race [adjusted odds ratio (adj. OR) 3.3, 95% CI = 2.0-5.4], age > or = 40 years (adj. OR 2.1, 95% CI = 1.2-3.8), and BMI > or = 30 kg/m2 (adj. OR 2.5, 95% CI = 1.5-4.0) were independently associated with large nodular goiter. No significant differences were observed in gender, family history of thyroid disease, pregnancy, or tobacco use (P > 0.1). CONCLUSIONS: African-American race, obesity, and increasing age are independent risk factors for the development of large nodular goiter. These results may be helpful in determining how best to monitor patients with nodular goiter, with earlier intervention to help prevent progressive enlargement and its sequelae.

Gestational diabetes mellitus: does it recur in subsequent pregnancy?

The recurrence of glucose intolerance was examined in 36 women with an index pregnancy complicated by gestational diabetes who received antepartum care at the same institution because of a subsequent pregnancy. Standard oral or intravenous glucose tolerance tests were used to document glucose intolerance or gestational diabetes. Twenty patients had gestational diabetes in the subsequent pregnancy, whereas one third of the patients tested did not demonstrate an abnormality of carbohydrate metabolism. The patients with consecutive pregnancies complicated by gestational diabetes were heavier and were delivered of heavier neonates than the patients who did not develop gestational diabetes again. Unlike the nondiabetic group, the patients who remained gestationally diabetic weighed significantly more in the subsequent pregnancy than in the index pregnancy. These results indicate that patients with gestational diabetes should be tested in subsequent pregnancies because of the impact of gestational diabetes on birth weight. However, these results also suggest that the glucose tolerance test may not be a reliable test for the detection of abnormal carbohydrate metabolism.

Rheologic properties of mixed hemoglobin gels: deoxyhemoglobins S and F.

To obtain new information concerning the behaviors--and in turn, the structures--of gels formed from mixtures of S and F hemoglobins, their rheologic properties have been characterized by stress relaxation. The variables manipulated were (1) initial total hemoglobin concentration; (2) mole fraction of hemoglobin S present in the mixture; (3) hemoglobin F as only intact tetramer or as both tetramers and hybridized hemoglobin; (4) hemoglobin F as predominantly G gamma, A gamma, or a mixture of gamma chain types; (5) annealing time; (6) shear history, (7) temperature; and (8) temperature and time of annealing. Characteristics monitored to gain information about the effect of these variables on gel properties were (1) lag time, (2) polymer mass, (3) polymer fraction, (4) polymer composition, (5) equilibrium total hemoglobin activity, and (6) solidity/total or hemoglobin S polymer mass (or total or hemoglobin S fraction). As expected, mixed hemoglobin S and F gels were less solid than pure hemoglobin S gels of similar initial total hemoglobin concentrations because of lower polymer mass, and gel properties were influenced by annealing time, shear history, temperature, and temperature and time of annealing. However, when solidities were compared on the basis of similar quantities of gel present, mixed hemoglobin S and F gels were found to be more solid than those of pure S as the mole fraction of hemoglobin S decreased in the initial mixture. This is explained by the predominant influence on gel properties of high hemoglobin activity incurred by the volume exclusion effect of the total hemoglobin concentration. Pathophysiologic implications of these findings for various sickle cell disorders are proposed.

Rheologic properties of mixed hemoglobin gels: deoxyhemoglobins S and A.

To obtain new information concerning the behaviors, and in turn the structures, of gels formed from mixtures of S and A hemoglobins, their physical properties have been characterized by stress relaxation with a rotational rheometer. The variables manipulated were (1) initial total hemoglobin concentration, (2) mole fraction of hemoglobin S present in the mixture, (3) hemoglobin A as intact tetramer only or as both tetramer and hybridized hemoglobin AS, (4) annealing time, (5) shear history, (6) temperature, and (7) temperature and time of annealing. Characteristics monitored to gain information about the effect of these variables on gel properties were (1) lag time, (2) polymer mass, (3) polymer fraction, (4) polymer composition, (5) equilibrium total hemoglobin activity, and (6) solidity/total or hemoglobin S polymer mass (or total or hemoglobin S fraction). As expected, mixed hemoglobin SA gels were less solid than those of pure S of similar initial hemoglobin concentrations because of lower polymer mass, and gel properties were influenced by shear history, annealing time, temperature, and temperature and time of annealing. However, when solidities were compared on the basis of similar quantities of gel present, mixed hemoglobin SA gels were found to be more solid than those of pure S as the mole fraction of hemoglobin S decreased in the initial mixture. This is explained by the predominant influence on gel properties of high hemoglobin activity incurred by the volume exclusion effect of the total hemoglobin concentration. The presence of hemoglobin A with hemoglobin S results in polymers and gels that differ from those found in pure hemoglobin S. Pathophysiologic implications of these findings for sickle cell disorders are proposed.

Comparison of dimercaptosuccinic acid and calcium disodium ethylenediaminetetraacetic acid versus dimercaptopropanol and ethylenediaminetetraacetic acid in children with lead poisoning.

OBJECTIVES: To compare the response to dimercaptopropanol (BAL) and calcium disodium ethylenediaminetetraacetic acid (EDTA) versus orally administered meso-2,3-dimercaptosuccinic acid (DMSA) and EDTA in children with lead poisoning. METHODS: Retrospective review of medical records of children admitted to MetroHealth Medical Center with a whole blood lead (BPb) concentration of 2.17 mumol/L (45 micrograms/dl) or more (or less than 2.17 mumol/L and not a candidate for outpatient oral chelation) and treated with BAL + EDTA or DMSA + EDTA. In each group, the mean BPb values at the end of therapy and at 14 and 33 days after chelation were compared with pretreatment BPb by the Wilcoxon signed-rank test, whereas the Mann-Whitney U test was used to compare percentage change from pretreatment at each follow-up day between the two groups. RESULTS: Twenty-three children received BAL + EDTA and 22 received DMSA + EDTA. The BPb values (mean +/- SD) at the end of therapy and at 14 and 33 days after chelation were significantly lower than pretreatment in both groups (BAL + EDTA: 17 +/- 10, 34 +/- 7, 36 +/- 11 vs 58 +/- 14 micrograms/dl, p < 0.02, 0.01, 0.001, respectively; DMSA + EDTA: 10 +/- 4, 30 +/- 10, 30 +/- 14 vs 50 +/- 10 micrograms/dl, p < 0.01, 0.001, 0.01, respectively). The percentage reduction (mean +/- SD) in BPb from pretreatment at the end of therapy and on days 14 and 33 after chelation did not differ between the groups (BAL + EDTA: -71.2% +/- 19.8%, -40.2% +/- 13.8%, -37.1% +/- 17%; DMSA + EDTA: -79.9% +/- 8.7%, -38.3% +/- 21.6%, -37% +/- 32%; p > 0.20). Elevation of alanine aminotransferase and vomiting during therapy were observed more frequently in the BAL + EDTA group compared with the DMSA + EDTA group. CONCLUSIONS: Treatment with DMSA or BAL combined with EDTA results in a comparable reduction in BPb.

Relative activation of milk lipoprotein lipase by serum of cows fed varying amounts of fat.

A routine laboratory assay to evaluate relative concentrations of lipoprotein lipase activator (apo C-II) in cow serum was developed. The assay was linear for at least 120 min after an initial, unexplained, lag ime of 13 to 15 min. Half-maximal activation was in the range of 1 to 2% serum in the assay. Inhibition of activation was indicated at high amounts (10%) of serum. Activation from plasma was half that from serum, presumably caused by an increase in substrate Km in the presence of heparin. Use of glyceryl tri[9,10-3H] oleate yielded excessively high blanks; [2-3H] glyceryl triolein is suggested for routine assay. Relative amounts of activator were not different between dry and lactating cows fed "conventional" diets. Activator concentration increased linearly with increasing dietary fat and was related to concentration of total lipid in plasma. The assay may provide a useful adjunct in studies on lipoprotein metabolism.

Improved outcome after early fixation of acetabular fractures.

This study was done in order to evaluate the effect of the timing of fixation for acetabular and pelvic ring fractures on patient outcome. Demographic, clinical and outcome data for 5821 trauma patients admitted from January 1993 through January 1996 were retrospectively reviewed. Pelvic fractures were classified according to Young and Burgess. Patients who had fixation within 24 h of admission were compared with those who had later operation. Main outcome measures were Multiple Organ Dysfunction Score according to Moore, hospital and intensive care unit length of stay and discharge disposition. Out of 416 patients with pelvic fractures, one hundred patients had fracture fixation [90 open reduction and internal fixation, 10 external fixation]. There were 59 acetabular fractures and 41 pelvic ring fractures. The overall mortality was 4%. Early fixation of acetabular fractures was associated with lower MODS (p < 0.006) and decreased total length of stay (p < 0.026). Length of hospital stay was also less with early fixation of pelvic ring fractures (p < 0.04). Functional outcome was improved in early fixation of acetabular fractures with a greater proportion of patients being discharged home rather than to rehabilitation or skilled care (p = 0.05). Patients who underwent early repair of acetabular and pelvic ring fractures had a shorter length of hospital stay compared to those with late fixation. Patients with early repair of acetabular fractures had significantly less organ dysfunction and exhibited improved functional outcome.
