Background. Postoperative pulmonary complications are one of the important causes of postoperative morbidity and mortality associated with anesthesia and surgery. Mechanical ventilation settings influence the emergence of postoperative pulmonary complications. The aim of this study is to investigate the influence of tidal volume 6 mL/kgBW and 10 mL/kgBW with PEEP 6cmH2O to pulmonary function which is measured by the ratio of PaO2 / FiO2.Methods. This study is a single center randomized clinical trial on patients undergoing elective major abdominal surgery at Cipto Mangunkusumo Hospital in November 2014 to April 2015. A total of 52 subjects were taken with consecutive sampling method. The subjects were randomized into two groups: the group receiving tidal volume 6 mL/kgBW with PEEP 6 cmH2O and the group receiving tidal volume of 10 mL/kgBW with PEEP 6 cmH2O. The primary output is the assessment of pulmonary function using the ratio of PaO2/FiO2. Secondary outputs are pulmonary complications (pneumonia, atelectasis, ARDS, respiratory failure), extrapulmonary complications (SIRS, sepsis, severe sepsis), and mortality within 28 days postoperative.Results. The two intervention groups had similar characteristics at baseline. There are no significant PaO2 / FiO2 ratio differences between the VT - 6 mL/kgBB with VT - 10 mL/kgBB, at the start of the operation (p=0,14), the end of surgery (p=0.44), the first postoperative day (p=0,23), and the second postoperative day (p=0,39) . There is no significant difference in the secondary outcomes in form of pulmonary complications until postoperative day 7, extrapulmonary complications until postoperative day 7, and in 28-days postoperative mortality between the two groups.Conclusions : Tidal volume of 6 to 10 mL/kg with PEEP 6 cmH2O are safe for use in patients undergoing major abdominal surgery."

ABSTRACTBACKGROUND: Elective craniotomy is associated with high incidence of postoperative pulmonary complications/PPC (25%) and mortality (10%). Low tidal volume as part of lung protective strategy is known to decrease PPC. We determined to study the effect of low tidal volume solely to postoperative PaO2/FiO2 ratio (PF ratio) in elective craniotomy.METHODS: This was a randomised control trial in one university hospital in Indonesia. Fifty two patients underwent elective craniotomy (age 18-60 years, duration of surgery >4 hours, normal lung) were ventilated with tidal volume 6 mL/kg (VT-6) or 10 mL/kg (VT-10) perioperatively. We hypothesized that postoperative PaO2/FiO2 ratio in VT-6 is higher than VT-10. Blood gas analysis were measured at 1 hour postinduction, at end of surgery, at 24 hours postinduction and 48 hours postinduction. Postoperative pulmonary complications (atelectasis, pneumonia, ARDS, respiratory failure) were observed on day 7 and mortality on day 28.RESULTS: PaO2/FiO2 ratio of VT-6 and VT-10 respectively: at 1 hour postinduction, 413.7 ± 113.4 mmHg and 401.5 ± 106.3 mmHg (p = 0.69); at end of surgery, 466.6 ± 94.6 mmHg and 471.1 ± 89.0 mmHg (p = 0.86); at 24 hours postinduction, 418.8 ± 108.8 and 448.5 ± 119.6 mmHg (p = 0.35); at 48 hours postinduction, 414.9 ± 88.1 mmHg and 402.5 ± 100.7 mmHg (p = 0.63). Pneumonia were found in 1 (3.8%) patient in group VT-6 and 2 (7.6%) patients in group VT-10. SIRS were found in 1 (3.8%) in group VT-6 and 2 (7.6%) in group VT-10. No other pulmonary/extrapulmonary complications and mortality were found in this study.CONCLUSION: Perioperative mechanical ventilation with lower tidal volume (6 mL/kg) does not result in higher postoperative PaO2/FiO2 ratio compared to higher tidal volume (10 mL/kg) in healthy lung patients undergone elective craniotomy. Incidence of postoperative pulmonary/extrapulmonary complications and mortality were similar between both groups. , BACKGROUND: Elective craniotomy is associated with high incidence of postoperative pulmonary complications/PPC (25%) and mortality (10%).

"Penggunaan ventilasi mekanis pada pasien kritis tidak dapat dihindarkan namun dapat menyebabkan ventilator-induced lung injury (VILI) dan ventilator-induced diaphragm dysfunction (VIDD). Penelitian ini bertujuan untuk menilai hubungan antara volume tidal rendah (6 ml/kgBB) dan tinggi (10 ml/kgBB) terhadap disfungsi diafragma. Penelitian ini merupakan sebuah randomized controlled trial yang dilakukan di ruang perawatan intensif, RS Cipto Mangunkusumo. Pasien secara random masuk ke kelompok volume tidal 6 ml/kgBB dan 10 ml/kgBB, dan diikuti selama 72 jam (3 hari) untuk dinilai adanya disfungsi diafragma. Disfungsi diafragma dinilai menggunakan alat ultrasonografi, menggunakan kriteria ekskursi dan fraksi ketebalan diafragma. Variabel lain yang dinilai dalam penelitian ini ialah kadar interleukin-6.Sebanyak 52 pasien dilakukan randomisasi. Sebanyak total 45 pasien menyelesaikan studi. Tidak terdapat perbedaan karakteristik dasar sampel pasien pada kedua kelompok volume tidal. Sebanyak 37.8% pasien mengalami disfungsi diafragma pada hari ketiga. Tidak terdapat perbedaan proporsi disfungsi diafragma pada kedua kelompok volume tidal baik menggunakan kriteria ekskursi, fraksi ketebalan, maupun salah satunya. Terdapat perbedaan rerata interleukin-6 hari nol antara kelompok dengan dan tanpa disfungsi diafragma hari ketiga sebesar 332.29 pg/mL (p=0.024). Sebagai kesimpulan, volume tidal 6 ml/kgbb dan 10 ml/kgbb tidak berbeda dalam mencegah disfungsi diafragma pada pasien kritis. Interleukin-6 memiliki pengaruh terhadap disfungsi diafragma.

The use of mechanical ventilation is inevitable for critically ill patients yet it causes tremendous side effect of ventilator-induced lung injury (VILI) and ventilator-induced diaphragm dysfunction (VIDD). This study is aimed to examine the effect of low tidal volume (6 ml/kgBW) and high tidal volume (10 ml/kgBW) to diaphragm dysfunction. This is a randomized controlled trial conducted at intensive care unit (ICU) of Cipto Mangunkusumo Hospital. Patients were randomly allocated to tidal volume of 6 ml/kgBW or 10 ml/kgBW and were followed for 72 hours (3 days). At the end of the 72 hours, patients were assessed for diaphragm dysfunction. Diaphragm dysfunction is assessed by ultrasonography with excursion and thickness fraction criteria. Interleukin-6 was also examined. Of 52 patients who were randomized, 25 were on 6 ml/kgBW group and 27 were on the other. There were 45 patients finishing the study. The baseline characteristics of the sample was not different among the two groups. We found 37.8% patients with diaphragm dysfunction on day-3 but no significant proportion difference among the two groups. Diaphragm dysfunction was assessed with excursion, fraction of thickness criteria. We found 332.29 pg/mL mean difference between interleukin-6 on patients with and without diaphragm dysfunction on day-3 (p=0.024). In conclusion, tidal volume of 6 ml/kgBW and 10 ml/kgBW is not different in preventing diaphragm dysfunction on critically ill."

Background: Laparoscopy is a procedure that is profitable on a kidney transplant operation. However, this technique may cause changes in the respiratory system. Tidal volume setting is one of protection strategies for preventing pulmonary complications postoperative. This study attempted to compare the effects of tidal volume 6 mL kgbw and 10 mL kgbb kgbw against distribution of ventilation in kidney transplant donor patients who underwent laparoscopic nephrectomy using EIT.

Method: This randomized clinical trial conducted in the Surgical Center Installation RSUPN Cipto Mangunkusumo and operating room RSCM Kencana Jakarta against 30 kidney transplant donor patients who underwent laparoscopic nephrectomy. Subjects were randomized into two intervention groups mechanical ventilation with intraoperative tidal volume 6 mL kgbw and 10 mL kgbw. The hypothesis is distribution of ventilation tidal volume 6 mL kgbw is better than 10 mL kgbw. Parameter TIV, EELI global and regional and CR were taken from a monitor EIT PulmoVista 500.

Result: The value of TIV between dependent and nondependent parts of lung statistically significant difference on postdesuflation supine position p 0,008 , where the tidal volume of6 mL kgbw indicates distribution of ventilation is not homogenous. The value of EELI global and regional tidal volume 10 mL kg is higher and meaningful statistically on lateral decubitus before insuflation p 0,005 . There is no meaningful difference in CR value the dependent and nondependent parts of lung.

Conclusion: Tidal volume 6 mL kgbw does not give a better distribution of ventilation compared with 10 mL kgbw in kidney donor patient undergoing laparoscopic nephrectomy based on the parameters of the EIT.Keywords Distribution of ventilation, EIT, kidney donor, laparoscopic nephrectomy, intraoperative volume tidal."
