The effects of different abdominal pressures on pulmonary function test results in laparoscopic cholecystectomy

This study aimed to examine the effects of differing intra-abdominal pressures on pulmonary function test results in laparoscopic cholecystectomy. Forty-five patients were operated on under 3 different intra-abdominal pressures: group A (8 mm Hg), group B (12 mm Hg), and group C (15 mm Hg). On the first day before and after the operation, forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), FEV1/FVC rate, peak expiratory flow speed (PEF), and maximal middle expiration speed (FEF25-75) values were measured using Vmax 229 spirometry. No significant differences were observed among the 3 groups regarding preoperative and postoperative FVC, FEV1, FEV1/FVC, PEF, and FEF25-75 values (P=0.96, P=0.73, P=0.48, P=0.34, and P=0.33, respectively). When the groups' preoperative and postoperative values were compared, FVC, FEV1, and PEF values significantly decreased in each group. The FEF25-75 values statistically significantly decreased in groups B and C when compared with their preoperative values; however, the decrease in group A was not significant. In conclusion, different intra-abdominal pressures during laparoscopic cholecystectomy had similar effects on pulmonary function test results. However, lower intra-abdominal pressures were associated with slightly more negative effects on FEF25-75 values.

Open versus laparoscopic cholecystectomy. A comparison of postoperative pulmonary function.

Upper abdominal surgery is associated with characteristic changes in pulmonary function which increase the risk of lower lobe atelectasis. Sixteen patients undergoing open cholecystectomy and 20 patients undergoing laparoscopic cholecystectomy were prospectively evaluated by pulmonary function tests (forced vital capacity [FVC], forced expiratory volume [FEV-1], and forced expiratory flow [FEF] 25% to 75%) before operation and on the morning after surgery to determine if the laparoscopic technique lessens the pulmonary risk. Fraction of the baseline pulmonary function was calculated by dividing the postoperative pulmonary function by the preoperative pulmonary function and multiplying by 100%. Postoperative FVC measured 52% of preoperative function for open cholecystectomy and 73% for laparoscopic cholecystectomy (p = 0.002). Postoperative FEV-1 measured 53% of baseline function for open cholecystectomy and 72% for laparoscopic cholecystectomy (p = 0.006). Postoperative FEF 25% to 75% measured 53% for open cholecystectomy and 81% for laparoscopic cholecystectomy (p = 0.07). It is concluded that laparoscopic cholecystectomy offers improved pulmonary function compared to the open technique.     

Postoperative pulmonary function after laparoscopic and open cholecystectomy

In this prospective, randomized study, we compared 42 patients undergoing laparoscopic cholecystectomy and 40 undergoing open cholecystectomy to determine if laparoscopic cholecystectomy results in less respiratory impairment and fewer respiratory complications. Pulmonary function tests, arterial blood-gas analysis and chest radiographs were obtained in both groups before operation and on the second day after operation. Postoperative pain scores and analgesic requirements were also recorded. After operation, a significant reduction in total lung capacity, functional residual capacity (FRC), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and mid-expiratory flow (FEF25-75%) occurred after both laparoscopic and open cholecystectomy. The reductions in FRC, FEV1, FVC and FEF25-75% were smaller after laparoscopic (7%, 22%, 19% and 23%, respectively) than after open (21%, 38%, 32% and 34%, respectively) cholecystectomy. Laparoscopic cholecystectomy was also associated with a significantly lower incidence (28.6% vs 62.5%) and less severe atelectasis, better oxygenation and reduced postoperative pain and analgesia use compared with open cholecystectomy. We conclude that postoperative pulmonary function was impaired less after laparoscopic than after open cholecystectomy.      

Daily comparison of respiratory functions between on-pump and off-pump patients undergoing CABG.

OBJECTIVE: Widespread application of on-pump revascularization procedures is increasing due to the thought of elimination of untoward effects of cardiopulmonary circuit. Thus, whether off-pump coronary artery surgery eliminates side effects especially related to respiratory functions is still controversial. Although many previous studies have evaluated these respiratory functions, daily comparison of 12 parameters was not included in any of the studies. The aim of our prospective study was to ascertain whether off-pump coronary operation improves pulmonary functions and postoperative recovery period when compared with on-pump technique and whether early discharge of patients with off-pump surgery is the result of respiratory improvement. METHODS: Eighteen patients in each group were included: on-pump group underwent coronary revascularization with cardiopulmonary bypass and off-pump with stabilization. Respiratory function tests and arterial blood gas analyses were performed preoperatively and daily after operation function tests included forced expiratory volume (FEV) in 1s, forced vital capacity (FVC), expiratory reserve volume, vital capacity, quotient of FEV in 1s to FVC, maximal voluntary ventilation (MVV), tidal volume, and forced midexpiratory flow. Blood gas analyses included partial arterial oxygen and carbon dioxide pressure, arterial pH and hematocrit (Hct). RESULTS: Preoperative pulmonary functions and arterial blood gases were not statistically significant between groups except MVV and partial arterial oxygen pressure. MVV was slightly higher in on-pump group and partial arterial oxygen pressure was slightly lower in on-pump group. During postoperative first day Hct (P=0.004) and FEV in 1s (P=0.049) values and third day partial arterial oxygen pressure (P=0.011) and Hct (P=0.011) values were lower in on-pump group. Mean extubation, duration in postoperative suit and hospital discharge times, mean blood loss were not statistically significant between groups postoperatively. CONCLUSION: Pulmonary functions and arterial blood gases were not improved in off-pump patients when compared with on-pump patients. Patients going to be surgically revascularized should not be altered to off-pump surgery merely with the hope of improving respiratory functions with off-pump technique. As the postoperative stay times at surgical theatre and hospital is not different and the extubation times were similar, early discharge of patients with off-pump surgery cannot be related merely to better preservation of respiratory functions.     

Postoperative pulmonary dysfunction after bilateral inguinal hernia repair: a prospective randomized study comparing the Stoppa procedure with laparoscopic total extraperitoneal repair (TEPP)

The infraumbilical incision required for open repair of bilateral inguinal hernia with a giant prosthesis is associated with postoperative pain and respiratory impairment. The aim of this study was to evaluate the postoperative respiratory dysfunction after bilateral hernia surgery. Thirty-nine patients were randomized into two groups: open repair according to the Stoppa technique and laparoscopic extraperitoneal repair (TEPP). Respiratory function tests were performed before and 24 hours after surgery. The two groups were well matched for age, American Society of Anesthesiologists (ASA) risk score, type of hernia, and preoperative lung function. The postoperative forced vital capacity (FVC), peak expiratory flow (PEF), and forced expiratory volume in 1 second (FEV 1.0) were significantly altered in both groups. The PEF dropped 15% in both groups. The FVC dropped 22% after Stoppa versus 25% after laparoscopy (P = 0.7). The FEV 1.0 dropped 21% after Stoppa versus 9% after laparoscopy (P = 0.12). We conclude that laparoscopic preperitoneal and open bilateral hernia repair are followed by similar ventilatory dysfunction, although a trend toward better postoperative FEV 1.0 was noted after laparoscopy. This might play a role in selected patients with severe pulmonary limitations. Overall, the limited drop in pulmonary function following bilateral hernia repair under general anesthesia may serve to explain the low pulmonary morbidity that follows these procedures.     

Pulmonary function for pectus excavatum at long-term follow-up

PURPOSE: The aim of this article was to assess whether and to what extent pulmonary function recovered to normal degree postoperatively and to investigate the changes in pulmonary function after surgical correction and the value of surgical correction. METHODS: A total of 27 patients who could be questioned and examined in person at the outpatient department of our hospital were included in this study. Of these patents, 24 were boys and 3 were girls. Their ages ranged from 3 to 16 years (mean, 8.67) at follow-up. The mean age at surgery was 4 years, and mean years of follow-up was 6.8. Pulmonary functional measurements included in vital capacity (VC), total lung capacity (TLC), residual volume (RV), functional residual capacity (FRC), RV-TLC ratio, maximal voluntary ventilation (MVV), force ventilatory capacity (FVC), forced expiratory volume in one second (FEV1), maximal midexpiratory flow curve (MMEF), maximal expiratory flow in 75% vital capacity (V75), maximal expiratory flow in 50% vital capacity (V50), maximal expiratory flow in 25% vital capacity (V25), and breathing reserve ratio (BR). RESULTS: TLC, FRC, MVV, MMEF, V75, and V50 values were not different from the normal values. IVC, FVC, FEV1, and V25 values were decreased significantly compared with the normal values. The RV and RV-TLC were high in 87.5% cases. CONCLUSIONS: Preoperative symptoms obviously improved after operation. There was little airway obstruction in the patients postoperatively. The patients with pectus excavatum should be operated on as soon as possible.     

Pulmonary function after lobectomy: video-assisted thoracic surgery versus thoracotomy

BACKGROUND: Whether video-assisted thoracic surgery (VATS) improves postoperative pulmonary function is still controversial. We compared postoperative pulmonary function after VATS lobectomy and standard lobectomy. METHODS: Eleven patients who had undergone standard lobectomy and 10 patients who had undergone VATS lobectomy were studied. Arterial blood gas analyses were performed on the 4th, 7th, and 14th postoperative days. Pulmonary function, including forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1.0), and peak flow rate (PFR) were measured on the 7th and 14th postoperative days (early phase), and approximately 1 year after surgery (late phase). RESULTS: Pulmonary function, as assessed with arterial oxygen partial pressure (PaO2) (p = 0.054), arterial oxygen saturation (O2SAT) (p = 0.063), FVC (p = 0.10), and FEV1.0 (p = 0.08), was better after VATS lobectomy than after thoracotomy on the 7th postoperative day. PFR was significantly better after VATS on both the 7th and 14th postoperative days (p = 0.008 and p = 0.03, respectively). CONCLUSIONS: VATS lobectomy had advantages on early postoperative pulmonary function. We conclude that VATS lobectomy is a beneficial alternative to standard thoracotomy, especially for patients with poor pulmonary reserve.     

Post-thoracotomy analgesia--comparison epidural fentanyl to intravenous pethidine

BACKGROUND AND METHODS. To evaluate the efficacy of postthoracotomy analgesia with intermittent epidural fentanyl. 50 patients were allocated randomly into 2 groups. The first group received intermittent epidural fentanyl and the second group received intermittent intravenous analgesia using pethidine. The variables studied were: pain score; total amount of additional intravenous opioid analgesia, and ventilatory function parameters [forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and FEV1/FVC ratio]. RESULTS. In the first postoperative day, pain scores were higher in the epidural group (P = 0.034), but there was no significant difference between mean pain scores in the second and third days (P = 0.61, P = 0.15, respectively). On all three days, significantly more additional analgesics were required in the epidural group. A difference was found between both groups in the post- to pre-operative FEV1, FVC and FEV1/FVC ratios, with the better preservation of the ventilatory function in the epidural group (P = 0.001, 0.013, <0.0001, respectively). CONCLUSION. The analgesic effect of intermittent epidural fentanyl is not adequate and postoperative pain relief has not any significant advantage over the more easily-applied intravenous analgesia. However, better preservation of ventilatory function makes epidural fentanyl a useful adjunct analgesia in reduction of post-thoracotomy pulmonary complications.
